Available in PDF, EPUB and Kindle. Book excerpt: The Deep Underground Neutrino Experiment (DUNE) will push forward the frontiers of our understanding of the physics governing neutrino interactions and oscillations. The performance of this experiment relies heavily upon a functional and well-calibrated system of near detectors (ND), comprised of three independent detectors. Of these three detectors, the upstream Liquid Argon Time Projection Chamber (LArTPC) is considered to be the primary target due to its precision and similarity to the DUNE far detector units. The ND LArTPC detector will utilize novel detection techniques such as a highly-segmented drift volume with modularized charge and light readout systems, a pixelated charge readout system for unabmiguous 3D reconstruction of charge, and integrated field shaping devices. These technologies, in combination with the high-rate environment of the Long Baseline Neutrino Facility (LBNF) beam necessitate careful understanding of the drift field and electronics response over time.This thesis describes the design of the integrated near detector program, including the Precision Reaction-Independent Spectrum Measurement (PRISM) system for high-precision measurement of the unoscillated neutrino flux at the beam source site. This system allows for motion of the two upstream ND components in the direction transverse to the beam source, allowing for sampling of off-axis flux, granting access to the angular dependence of beam production parameters, and enabling interaction model independent measurement of neutrino oscillation parameters. This thesis will also discuss a program for spatial calibration of the LArTPC component of the near detector system (ND-LAr, or ArgonCube) using both cosmic rays and a dedicated laser photoelectric charge injection system. Included is an example of this calibration scheme in the Module-0 and Module-1 prototype detectors and an analysis of the findings of these measurements.
Book Synopsis Liquid Argon Time Projection Chamber Calibration Using Cosmogenic Muons, and Measurement of Neutrino Induced Charged Kaon Production in Argon in the Charged Current Mode (MicroBooNE Experiment) by : Varuna Crishan N Meddage
Download or read book Liquid Argon Time Projection Chamber Calibration Using Cosmogenic Muons, and Measurement of Neutrino Induced Charged Kaon Production in Argon in the Charged Current Mode (MicroBooNE Experiment) written by Varuna Crishan N Meddage and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The MicroBooNE experiment at Fermilab uses the novel LArTPC technology to reconstruct neutrino interactions with liquid argon. The experiment consists of a detector having an active mass of 85 tons of liquid argon, where the operational electric field of the TPC is 0.273 kV/cm. While BNB neutrino beam at Fermilab is the main source for neutrinos for the experiment having an average energy of ~0.8 GeV, the NUMI neutrino beam at Fermilab also provides high energy neutrinos to perform different physics analyses. The MicroBooNE experiment has been in operation since october 2015. Its major physics goals include investigating into the anomalous production of electron neutrino like events as observed by MiniBooNE and LSND experiments and detail studies of neutrino-argon cross sections at lower neutrino energies. Moreover, the experiment will also serve as R&D for future LArTPC experiments like the already proposed SBN and DUNE programs. One of the major operational requirements of any LArTPC experiment including MicroBooNE is to achieve a high liquid argon purity keeping the electronegative contaminants like H2O and O2 at low concentration levels. This dissertation first describes how to perform an electron attenuation measurement using cosmogenic muons, which provides a handle over the the amount of electronegative impurities inside our detector medium. Likewise this measurement also serves as the first step towards reconstruction of particle energies as MicroBooNE must compensate for the loss of ionization electrons due to capture by electronegative contaminants. Secondly, the discussion is about how to calibrate any LArTPC detector in removing any spatial and temporal variations of the dQ/dx (charge deposited per unit length) spectrum using cosmogenic muons and then how to calculate correct energies of particle interactions with these calibrated out dQ/dx values. The translation of dQ/dx to particle energies (dE/dx - energy deposited per unit length) makes use of the stopping muons coming from neutrino interactions as the standard candle. The final discussion is about the neutrino induced charged kaon production at charged current mode in the lower neutrino energies of MicroBooNE experiment. This measurement is crucial as there is no such measurement so far on argon at the scale of neutrino energies used for MicroBooNE while already existing measurements on lighter nuclear targets are also sparse. This dissertation presents the first identified neutrino induced kaon candidates in MicroBooNE.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrinos are an interesting type of particle that could provide insight to unanswered questions such as the imbalance of matter and antimatter in the universe. However, they're difficult, if not impossible, to detect directly. Modern particle physics experiments build detectors called Liquid Argon Time Projection Chambers (LArTPCs) that detect the products of neutrino interactions. Due to various processes that take place within the detector, the data that comes out of these detectors ends up being distorted; various calibration techniques are necessary to ensure that the data is accurate and undistorted. All of these aspects of LArTPCs are complex on their own, let alone when they are all occurring in tandem. In this paper I will describe the basic principles behind LArTPC operation and data collection, and the calibration techniques that are carried out in the detector. I will also provide a brief comparison of various data from several of the more recent LArTPC experiments. This description of basic principles may prove useful to people who are familiarizing themselves with LArTPC experiments as part of their research endeavors.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 4 10 kt Liquid Argon Time Projection Chambers (LAr-TPCs) of the future DUNE experiment will enable precise measurements of the oscillation parameters and the discovery of CP violation for leptons, thanks to their excellent 3D imaging capabilities coupled with a high resolution calorimeter. One or more modules of the DUNE detector may exploit a dual phase (DP) LAr-TPC that, relying on the extraction of the charge produced in the liquid volume and its subsequent multiplication in argon gas, will increase the expected granularity and energy resolution. This thesis work present the simulation and reconstruction strategies of charged particles in a dual-phase LArTPC in the context of the DUNE experiment and its preliminary validation using cosmic ray data from the CERN 4 t demonstrator.
Book Synopsis Characterization of Liquid Argon Response for the Direct Detection of Dark Matter by : Benjamin R. Schlitzer
Download or read book Characterization of Liquid Argon Response for the Direct Detection of Dark Matter written by Benjamin R. Schlitzer and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature of dark matter remains one of the most significant open questions in modern physics, despite the large body of astrophysical and cosmological evidence supporting its existence. The Weakly Interacting Massive Particle (WIMP) is a well-motivated candidate particle with mass in the range 1 GeV/c2 - 100 TeV/c2 and coupling to Standard Model matter at or below the weak scale. If WIMPs do exist, they should occasionally interact with baryonic particles and leave behind a small amount of energy. DarkSide is a phased experimental program which aims to detect the interaction of a WIMP with a liquid argon target in a dual-phase time projection chamber (TPC). In order to make a WIMP discovery, an accurate understanding of the signal region is required. To this end, small-scale experiments which measure the detector response to a recoiling argon nucleus (NR) or scattering with atomic electrons (ER) are critical in establishing results of the large-scale direct detection experiments. The Argon Response to Ionization and Scintillation (ARIS) experiment was designed to characterize liquid argon's response to both NR and ER events at low recoil energies using a small dual-phase TPC. This work presents a complete chronology of the ARIS experiment and analysis of the collected data. A detailed description of the design of the ARIS TPC and related subsystems is given, as well as an account of the commissioning and calibration performed at the University of California, Los Angeles. The inverse-kinematics neutron source LICORNE was used at the Institute De Physique Nucléaire Orsay to bombard the ARIS TPC with collimated low energy neutrons. Neutron detectors surrounding the TPC were used to tag events which scattered in the TPC at selected angles, and the resulting data were used to characterize both NR and ER events at tightly constrained recoil energies. A description of the low-level reconstruction and data selection cuts is given, as well as corrections made due to trigger efficiency and vertical position in the TPC. ER data were analyzed to provide an improved measurement of the linearity of LAr light yield for incident [gamma]/[beta] particles with energies below 511 keV. ARIS measured a constant light yield to within 1.6% in the [41.5, 511] keV recoil energy range. The linearity of the ER scintillation response measured by ARIS has also been used to derive the spectral shape of forbidden 39Ar [beta] decay, which is a background intrinsic to liquid argon. The NR data were analyzed to measure the relative scintillation efficiency for recoils between [7.1, 117.8] keV, and were in good agreement with the previous SCENE results at low recoil energy. The DarkSide collaboration has used ARIS results to precisely model the response of nuclear recoils in liquid argon in both field-on and field-off configurations. In addition to the characterization of argon response, this work presents an optimization of the electric fields used to drift ionization electrons in DarkSide TPCs. The relevant electrostatics models used by COMSOL simulation software to approximate electric field behavior are described, as well as a technique developed to quantify field uniformity in the TPC. Then, the uniformity of the electric field is optimized for several possible TPC design changes, including the fiducial radius, the first shaping ring voltage, and the cross-sectional geometry of shaping rings. This work was supervised by Dr. Emilija Pantic, and was completed in collaboration with both members of the DarkSide collaboration as well as scientists at the University of California, Davis.

Download or read book Particle Detectors written by Hermann Kolanoski and published by Oxford University Press. This book was released on 2020-06-30 with total page 949 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the fundamentals of particle detectors as well as their applications. Detector development is an important part of nuclear, particle and astroparticle physics, and through its applications in radiation imaging, it paves the way for advancements in the biomedical and materials sciences. Knowledge in detector physics is one of the required skills of an experimental physicist in these fields. The breadth of knowledge required for detector development comprises many areas of physics and technology, starting from interactions of particles with matter, gas- and solid-state physics, over charge transport and signal development, to elements of microelectronics. The book's aim is to describe the fundamentals of detectors and their different variants and implementations as clearly as possible and as deeply as needed for a thorough understanding. While this comprehensive opus contains all the materials taught in experimental particle physics lectures or modules addressing detector physics at the Master's level, it also goes well beyond these basic requirements. This is an essential text for students who want to deepen their knowledge in this field. It is also a highly useful guide for lecturers and scientists looking for a starting point for detector development work.

Book Synopsis Pulse Shape Discrimination Studies in Liquid Argon for the DEAP-1 Detector by : Jeffrey Jack Lidgard
Download or read book Pulse Shape Discrimination Studies in Liquid Argon for the DEAP-1 Detector written by Jeffrey Jack Lidgard and published by . This book was released on 2008 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detector with a target mass of 7 kg of liquid argon was designed, constructed and operated at Queen's University. This detector is a scaled model for the DEAP project toward a tonne-scale argon detector to search for the WIMP candidate of the so far undetected, dark matter of the universe. The primary intent of the scaled detector was to measure the achievable level to reject background events by use of pulse shape discrimination, being based upon the scintillation timing properties of liquid argon. After refining the apparatus and components, the detector was in operation from the 20th of August until the 16th of October 2007 before being moved to its current location in SNOLAB. During this time, a population of 31 million well-tagged gamma events were collected, of which 15.8 million were in the energy range of interest for calibration. This population was sufficient to demonstrate the discrimination of background events by pulse shape discrimination at the level of 6.3 x 10-8. An analytical model was constructed, based on the scintillation processes and detector response, and has been sufficiently investigated to make predictions of further achievable discrimination.

Download or read book A G/NARRLI Effort written by Tenzing Henry Yatish Joshi and published by . This book was released on 2014 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid argon has long been used for particle detection due to its attractive drift properties, ample abundance, and reasonable density. The response of liquid argon to low-energy (100-10,000 eV) interactions is, however, largely unexplored. Weakly interacting massive particles such as neutrinos and hypothetical dark-matter particles (WIMPs) are predicted to coherently scatter on atomic nuclei, leaving only an isolated low-energy nuclear recoil as evidence. The response of liquid argon to low-energy nuclear recoils must be studied to determine the sensitivity of liquid argon based detectors to these unobserved interactions. Detectors sensitive to coherent neutrino-nucleus scattering may be used to monitor nuclear reactors from a distance, to detect neutrinos from supernova, and to test the predicted behavior of neutrinos. Additionally, direct detection of hypothetical weakly interacting dark matter would be a large step toward understanding the substance that accounts for nearly 27% of the universe. In this dissertation I discuss a small dual-phase (liquid-gas) argon proportional scintillation counter built to study the low-energy regime and several novel calibration and characterization techniques developed to study the response of liquid argon to low-energy (100-10,000 eV) interactions.
