Book Synopsis Beam Instrumentation and Diagnostics by : Peter Strehl
Download or read book Beam Instrumentation and Diagnostics written by Peter Strehl and published by Springer Science & Business Media. This book was released on 2006-06-18 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the experience of many years of teamwork with my group, the beam diagnostics group of GSI. For a long time the group was also responsible for operating the machines and application programming. In my opinion, this connection was very e?cient: ?rst, because a beam diagnostic system has to place powerful tools at the operators’ disposal; second, because data evaluation and presentation of results for machine operation demand application programs which can be handled not only by skilled experts. On the other hand, accelerator developments and improvements as well as commissioning of new machines by specialists require more complex measu- ments than those for routine machine operation. A modern beam diagnostic system, including the software tools, has to cover these demands, too. Therefore, this book should motivate physicists, constructors, electronic engineers, and computer experts to work together during the design and daily use of a beam diagnostic system. This book aims to give them ideas and tools for their work. I would not have been able to write this book without a good education in physics and many discussions with competent leaders, mentors, and c- leagues. After working about 40 years in teams on accelerators, there are so many people I have to thank that it is impossible to mention them all by name here.

Book excerpt: The Neutrinos at the Main Injector (NuMI) facility is a conventional neutrino beam which produces muon neutrinos by focusing a beam of mesons into a long evacuated decay volume. We have built four arrays of ionization chambers to monitor the position and intensity of the hadron and muon beams associated with neutrino production at locations downstream of the decay volume. This article describes the chambers construction, calibration, and commissioning in the beam.
Book Synopsis Addendum to NuMI Shielding Assessment by :
Download or read book Addendum to NuMI Shielding Assessment written by and published by . This book was released on 2007 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original safety assessment and the Safety Envelope for the NuMI beam line corresponds to 400 kW of beam power. The Main Injector is currently capable of and approved for producing 500 kW of beam power2. However, operation of the NuMI beam line at 400 kW of power brings up the possibility of an occasional excursion above 400 kW due to better than usual tuning in one of the machines upstream of the NuMI beam line. An excursion above the DOE approved Safety Envelope will constitute a safety violation. The purpose of this addendum is to evaluate the radiological issues and modifications required to operate the NuMI beam line at 500 kW. This upgrade will allow 400 kW operations with a reasonable safety margin. Configuration of the NuMI beam line, boundaries, safety system and the methodologies used for the calculations are as described in the original NuMI SAD. While most of the calculations presented in the original shielding assessment were based on Monte Carlo simulations, which were based on the design geometries, most of the results presented in this addendum are based on the measurements conducted by the AD ES & H radiation safety group.

Book Synopsis Neutron Beam Monitoring for Single-event Effects Testing by : Lyn Hongyu Zhang
Download or read book Neutron Beam Monitoring for Single-event Effects Testing written by Lyn Hongyu Zhang and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The research described in this thesis aims to develop a neutron beam monitoring system using silicon photodiodes as the detecting elements for accelerated testing of electronics against neutron-induced single event effects (SEEs). The system can measure the transmission along the neutron beam line where several devices are tested simultaneously, allowing beam degradation by upstream experiments to be taken into account. In signal processing, the pulse events from the output of the sensor are extracted by using a matched filter. This technique allows the pulse events to be detected effectively at a low false event rate. The pulse arrival times are acquired using the nonparalyzable counting system, which allows the interaction rates to be determined either indirectly based on the decay constant of the pulse interval distributions or directly on the basis of detection rates and sensor pulse widths. The optimum of sensor pulse width has been investigated in order to achieve the maximum of probability of detection with adequate energy resolution. A series of calculations have been undertaken to verify the correct operation of the detection software and to investigate system performance variations. Results from irradiations at various neutron facilities where SEEs experiments can be carried out, such as Los Alamos Neutron Science Center (LANSCE), Tri-University Meson Facility (TRIUMF) and The Svedberg Laboratory (TSL) neutron beam, are presented and analyzed. The measurement of transmission in the neutron beam can be made via the measured pulse height spectra, pulse interval distributions and responses of the sensor irradiated. As the beam can be scattered, absorbed or enhanced by upstream devices, there are likely to be fluctuations in the transmission along the neutron beam, which can also be characterized by the beam monitoring system. The recommended protocols for beam monitoring used at each neutron facility are investigated. At a low interaction rate, the protocols depend on the neutron fluence provided by the facility and the response of the sensor. At a high interaction rate, the probability of detection of the sensor should be determined first, and then the protocols are based on the probability of detection, neutron fluence and the response. In this thesis, the protocols of the beam monitoring system for use at ISIS ChipIr are also predicted on the basis of the pulse interval distributions and the mean of detected energy. Based on the work undertaken in the project and presented in this thesis, suggestions are put forward for improving the monitoring system. Geant4 techniques can be used to model pulse height spectra so as to enable direct comparisons between theoretical simulations and experimental results. Furthermore, the protocols for beam monitoring for use at ChipIr as recommended in this thesis will be verified when neutron beams become available in the future.
Book Synopsis 1 NA Beam Position Monitoring System by :
Download or read book 1 NA Beam Position Monitoring System written by and published by . This book was released on 1997 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: A system has been developed at Jefferson Lab for measuring transverse position of very low current beams delivered to the Experimental Hall B of the Continuous Electron Beam Accelerator Facility (CEBAF). At the heart of the system is a position sensitive cavity operating at 1497 MHz. The cavity utilizes a unique design which achieves a high sensitivity to beam position at a relatively low cavity Q. The cavity output RF signal is processed using a down-converter and a commercial lock-in amplifier operating at 100 kHz. The system interfaces with a VME based EPICS control system using the IEEE, 488 bus. The main features of the system are simple and robust design, and wide dynamic range capable of handling beam currents from 1 nA to 1000 nA with an expected resolution better than 100 [mu]m. This paper outlines the design of the system.

Book Synopsis Proposal for Continuously-variable Neutrino Beam Energy for the NuMI Facility by : Adam Para
Download or read book Proposal for Continuously-variable Neutrino Beam Energy for the NuMI Facility written by Adam Para and published by . This book was released on 2006 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NuMI Facility was intended to be flexibly changed between 3 energies of beams, LE, ME, and HE. However, the changeover requires extensive downtime to move and realign horns and the target. We propose to implement a flexible arrangement where the target can be remotely moved in the beamline direction to change the beam energy and the horns remain fixed. In addition to having the attractive feature of keeping the horn optics fixed, the motion of the target can be performed more quickly and hence on a more frequent basis. We discuss potential increases in statistics in the high energy region, systematic cross-checks available, and the improved beam monitoring capabilities with such variable energy beams.
