Book excerpt: New generation accelerator-based x-ray light sources require high quality electron beams. Parameters such as transverse emittance (projected or "sliced"), energy spread and bunch length for beams in the nC charge range, need to be pushed beyond their present limits for the successful operation of light sources such as Energy Recovery Linacs (ERL) and Free Electron Lasers (FEL). At the same time, the demand for a high average brightness is also driving towards technologies capable of very high repetition rate operation. The overall performance is greatly determined at the accelerator injector and in particular, at the electron gun. In this note, we present a new concept for a high repetition-rate photoinjector, capable of providing pulses up to at least 1 MHz or more.

Available in PDF, EPUB and Kindle. Book excerpt: New generation accelerator-based X-ray light sources require high quality beams with high average brightness. Normal conducting L- and S-band photoinjectors are limited in repetition rate and D-C (photo)injectors are limited in field strength at the cathode. We propose a low frequency normal-conducting cavity, operating at 50 to 100MHz CW, to provide beam bunches of up to the cavity frequency. The photoinjector uses a re-entrant cavity structure, requiring less than 100 kW CW, with a peak wall power density less than 10 W/cm2. The cavity will support a vacuum down to 10 picoTorr, with a load-lock mechanism for easy replacement of photocathodes. The photocathode can be embedded in a magnetic field to provide correlations useful for emittance exchange. Beam dynamics simulations indicate that normalized emittances smaller than 1 mm-mrad are possible with gap voltage of 750 kV, with fields up to 20 MV/m at the photocathode, for 1 nanocoulomb charge per bunch after acceleration and emittance compensation. Long-bunch operation (10's of picosecond) is made possible by the low cavity frequency, permitting low bunch current at the 750 kV gap voltage.

Download or read book Pump Port Calculations for the VHF Photoinjector Cavity written by and published by . This book was released on 2007 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The VHF photoinjector cavity requires a vacuum in the 10-9 to 10-11 Torr range, depending on the type of photocathode selected. One possible arrangement of the vacuum pumps replaces the outer cavity wall with a series of slots, and outside the slots, getter pumps are located in the region shielded from the RF fields. Calculations were carried out to determine the frequency shift due to the slots, compared to a solid outer wall, the power density on the bars, and the field drop-off to the outer plenum.

Book Synopsis Accelerator Physics, Technology, and Applications by : Alex Chao
Download or read book Accelerator Physics, Technology, and Applications written by Alex Chao and published by World Scientific. This book was released on 2004 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally invented for generating the first artificial nuclear reactions, particle accelerators have undergone, during the past 80 years, a fascinating development that is an impressive example of the inventiveness and perseverance of scientists and engineers. Since the early 1980s, accelerator science and technology has been booming. Today, accelerators are the prime tool for high energy physics to probe the structure of matter to an unknown depth. They are also, as synchrotron radiation sources, the most versatile tool for characterizing materials and processes and for producing micro- and nanostructured devices. The determination of the structure of large biomolecules is presently among the best examples of the application of synchrotron radiation. Finally, accelerators have grown more and more important for medicine, which is relying on them for advanced cancer therapy and radio-surgery. And there are more applications, including the generation of neutrons for materials science, the transmutation of nuclear waste with simultaneous production of electrical power, the sterilization of medical supplies and of foodstuff, and the inspection of trucks by customs or security services. This book is meant to provide basic training in modern accelerators for students, teachers, and interested scientists and engineers working in other fields. It is a result of the 3rd International Accelerator School, held in 2002 in Singapore under the auspices of the Overseas Chinese Physics Association (OCPA). Reputable experts, including a recent prize-winner, cover the field of cyclic and linear accelerators from the basic theoretical tools to forefront developments such as the X-ray free electron laser or the latest proton therapy facilities under construction. Accelerators, the art of building them, and the science for understanding their function have become a very exciting field of research. This book conveys the excitement of the experts to the reader.

Book Synopsis Angle-Resolved Photoemission by : S.D. Kevan
Download or read book Angle-Resolved Photoemission written by S.D. Kevan and published by Elsevier. This book was released on 1992-05-15 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angle-resolved photoemission has become an indispensable tool for solid state and surface physicists and chemists. This book covers the underlying phenomenology of the technique, reviews its application to existing problems, and discusses future applications. The book is particularly timely given the significant improvements in experimental and theoretical methodology which have recently been or soon will be attained, namely, ultrahigh resolution studies using improved sources of synchrotron radiation, quasiparticle interpretation of measured dispersion relations and spectra, in situ growth of novel materials, etc. The technique has been applied predominantly to understand materials for which the one-electron paradigm is a reasonable approximation. Most chapters discuss this type of experiment: 2D and 3D states in metals and semiconductors, extrinsic states induced by adsorption, etc. Applications of the technique to materials where electron correlation plays a comparable role to that of solid state hybridization, ferro- and antiferromagnets, high Tc superconductors, etc. are rapidly growing in popularity. These areas are also discussed and a foundation is laid for further experiments in this direction. Almost all chapters contain comprehensive bibliographies and compendia of systems studied. The book has an extensive index which cross references applications and systems studied.
