Book excerpt: The MuCool Experiment has been continuing to take data with805 and 201 MHz cavities in the MuCool Test Area. The system uses rfpower sources from the Fermilab Linac. Although the experimental programisprimarily aimed at the Muon Ionization Cooling Experiment (MICE), wehave been studying the dependence of rf limits on frequency, cavitymaterial, high magnetic fields, gas pressure, coatings, etc. with thegeneral aim of understanding the basic mechanisms involved. The 201 MHzcavity, essentially a prototype for the MICE experiment, was made usingcleaning techniques similar to those employed for superconductingcavities and operates at its design field with very littleconditioning.

Book Synopsis Engines of Discovery by : Andrew Sessler
Download or read book Engines of Discovery written by Andrew Sessler and published by World Scientific. This book was released on 2014 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Engines of Discovery celebrated in words, images and anecdotes the accelerators and their constructors that culminated in the discovery of the Higgs boson. But even before the Higgs was discovered, before the champagne corks popped and while the television producers brushed up their quantum mechanics, a new wave of enthusiasm for accelerators to be applied for more practical purposes was gaining momentum. Almost all fields of human endeavour will be enhanced by this trend: energy conservation, medical diagnostics and treatment, national security, as well as industrial processing. Accelerators have been used most spectacularly to reveal the structure of the complex molecules that determine our metabolism and life. For every accelerator chasing the Higgs, there are now ten thousand serving other purposes. It is high time to move from abstract mathematics and philosophy to the practical needs of humankind. It is the aim of this revised and expanded edition to describe this revolution in a manner which will attract the young, not only to apply their curiosity to the building blocks of matter but to help them contribute to the improvement of the quality of life itself on this planet. As always, the authors have tried to avoid lengthy mathematical description. In describing a field which reaches out to almost all of today's cutting edge technology, some detailed explanation cannot be avoided but this has been confined to sidebars. References guide experts to move on to the journal Reviews of Accelerator Science and Technology and other publications for more information. But first we would urge every young physicist, teacher, journalist and politician to read this book. Contents: Electrostatic Accelerators; Cyclotrons; Linear Accelerators; Betatrons; Synchrotrons; Colliders; Neutrino Super Beams, Neutrino Factories and Muon Colliders; Detectors; High-Energy and Nuclear Physics; Synchrotron Radiation Sources; Isotope Production and Cancer Therapy Accelerators; Spallation Neutron Sources; Accelerators in Industry and Elsewhere; National Security; Energy and the Environment; A Final Word OCo Mainly to the Young. Readership: Scientists, research physicists, engineers and administrators at accelerator laboratories; general readers; undergraduates and graduates in physics, electrical engineering and the history of science."

Book Synopsis High Powered Tests of Dielectric Loaded High Pressure RF Cavities for Use in Muon Cooling Channels by :
Download or read book High Powered Tests of Dielectric Loaded High Pressure RF Cavities for Use in Muon Cooling Channels written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bright muon sources require six dimensional cooling to achieve acceptable luminosities. Ionization cooling is the only known method able to do so within the muon lifetime. One proposed cooling channel, the Helical Cooling Channel, utilizes gas filled radio frequency cavities to both mitigate RF breakdown in the presence of strong, external magnetic fields, and provide the cooling medium. Engineering constraints on the diameter of the magnets within which these cavities operate dictate the radius of the cavities be decreased at their nominal operating frequency. To accomplish this, one may load the cavities with a larger dielectric material. Alumina of purities ranging from 96 to 99.8% was tested in a high pressure RF test cell at the MuCool Test Area at Fermilab. The results of breakdown studies with pure nitrogen gas, and oxygen-doped nitrogen gas indicate the peak surface electric field on the alumina ranges between 10 and 15 MV/m. How these results affect the design of a prototype cooling channel cavity will be discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The high energy physics community is continually looking to push the limits with respect to the energy and luminosity of particle accelerators. In the realm of leptons, only electron colliders have been built to date. Compared to hadrons, electrons lose a large amount of energy when accelerated in a ring through synchrotron radiation. A solution to this problem is to build long, straight accelerators for electrons, which has been done with great success. With a new generation of lepton colliders being conceived, building longer, more powerful accelerators is not the most enticing option. Muons have been proposed as an alternative particle to electrons. Muons lose less energy to synchrotron radiation and a Muon Collider can provide luminosity within a much smaller energy range than a comparable electron collider. This allows a circular collider to be built with higher attainable energy than any present electron collider. As part of the accelerator, but separate from the collider, it would also be possible to allow the muons to decay to study neutrinos. The possibility of a high energy, high luminosity muon collider and an abundant, precise source of neutrinos is an attractive one. The technological challenges of building a muon accelerator are many and diverse. Because the muon is an unstable particle, a muon beam must be cooled and accelerated to the desired energy within a short amount of time. This requirement places strict requisites on the type of acceleration and focusing that can be used. Muons are generated as tertiary beams with a huge phase space, so strong magnetic fields are required to capture and focus them. Radio frequency (RF) cavities are needed to capture, bunch and accelerate the muons. Unfortunately, traditional vacuum RF cavities have been shown to break down in the magnetic fields necessary for capture and focusing.

Download or read book A Test of a Superconducting Solenoid for the MuCool RF Experiment written by and published by . This book was released on 2000 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of a series of tests of a 440-mm warm bore split solenoid used for testing 805 MHz RF cavities. The solenoid consists of two coils each 250-mm long separated by a gap of 140 mm. The solenoid was designed to operate in two modes; a solenoid mode with the two coils hooked in the same polarity and a gradient mode with the two coils hooked in opposite polarity. In the solenoid mode, the magnet is designed to produce an induction of 5 T over a region that is about 400 mm long. In the gradient mode, the solenoid produces a field gradient of 25 T per meter along the axis over a distance of about 300-mm. The solenoid was designed to carry a force of over 3 MN that pushes the two coils apart, when the magnet is operated in the gradient mode. In order to carry this force, the coils are encased within aluminum shells, both inside and outside. Since this solenoid is encased in aluminum and the coils are potted, training was observed. The magnet training history and magnet field measurements are presented in this report.
