Available in PDF, EPUB and Kindle. Book excerpt: The study of electron-positron (ee/sup -/) annihilation in storage ring colliders has been very fruitful. It is by now well understood that the optimized cost and size of ee/sup /minus// storage rings scales as E(sub cm/2 due to the need to replace energy lost to synchrotron radiation in the ring bending magnets. Linear colliders, using the beams from linear accelerators, evade this scaling law. The study of e/sup +/e/sup /minus// collisions at TeV energy will require linear colliders. The luminosity requirements for a TeV linear collider are set by the physics. Advanced accelerator research and development at SLAC is focused toward a TeV Linear Collider (TLC) of 0.5--1 TeV in the center of mass, with a luminosity of 1033−−1°sup 34/. The goal is a design for two linacs of less than 3 km each, and requiring less than 100 MW of power each. With a 1 km final focus, the TLC could be fit on Stanford University land (although not entirely within the present SLAC site). The emphasis is on technologies feasible for a proposal to be framed in 1992. Linear collider development work is progressing on three fronts: delivering electrical energy to a beam, delivering a focused high quality beam, and system optimization. Sources of high peak microwave radio frequency (RF) power to drive the high gradient linacs are being developed in collaboration with Lawrence Berkeley Laboratory (LBL) and Lawrence Livermore National Laboratory (LLNL). Beam generation, beam dynamics and final focus work has been done at SLAC and in collaboration with KEK. Both the accelerator physics and the utilization of TeV linear colliders were topics at the 1988 Snowmass Summer Study. 14 refs., 4 figs., 1 tab.

Book excerpt: At CERN, KEK, Novosibirsk and SLAC, serious thought is being given to the design of linear colliders in the 0.5--2.0 TeV center-of-mass energy range. This paper reviews current progress at SLAC toward the design of such a collider. No attempt is made here to summarize ongoing work at the other laboratories. However, research on linear colliders is clearly an international effort, and success at SLAC will be greatly expedited by communication and cooperation with other laboratories in the US and abroad. In addition to major programs at the laboratories mentioned above, contributions relevant to linear collider design are being made at DESY, LAL (Orsay), LBL, LLNL and elsewhere. 49 refs., 6 tabs.

Book excerpt: An electron/positron linear collider with a center-of-mass energy between 0.5 and 1 TeV is recognized as an important complement to the physics program of the LHC. The Next Linear Collider (NLC) is being designed by a US collaboration (FNAL, LBNL, LLNL, and SLAC) which is working closely with the Japanese collaboration that is designing the Japanese Linear Collider (JLC). The NLC/JLC main linacs are based on normal conducting 11 GHz rf. This paper will discuss the status of the NLC design. Results from the ongoing R & D programs, including the recently uncovered high gradient damage problem, will be discussed along with changes to the optical design and collider layout which were made to enhance the collider capabilities.

Book excerpt: Probing the frontiers of particle physics and delving into the mysteries of the universe and its beginnings require machines that can accelerate beams of fundamental particles to very high energies and then collide those beams together, producing a multitude of exotic subatomic particles. The proposed Next Linear Collider (NLC), being developed by Stanford Linear Accelerator Center (SLAC), Lawrence Livermore and Lawrence Berkeley national laboratories, and Fermi National Accelerator Laboratory (Fermilab), is such a machine. The NLC is expected to produce a variety of subatomic particles by smashing together electrons and their antimatter counterparts (positrons) at nearly the speed of light with energies in the teraelectronvolt (TeV) range. Plans are that the NLC will initially operate at 0.5 TeV and ultimately be scaled up to 1.5 TeV. (See S & TR, April 2000, pp. 12-16.) Work at the facility will complement the research to be conducted at another high-energy particle accelerator, the 14-TeV Large Hadron Collider at the European Laboratory for Particle Physics (commonly known by the acronym CERN from its former name) in Geneva, which is scheduled for completion in 2007. Achieving beam energy levels in the TeV range requires modulator systems that can convert ac line power--the same type of power one gets from the wall plug--into dc pulses. Ultimately, these pulses are transformed into radiofrequency (rf) pulses that ''kick'' the particles up to the required energy levels. Livermore scientists and engineers have designed a solid-state modulator to replace oldstyle modulators based on vacuum-tube technology. These new modulators promise to be far more efficient, reliable, and serviceable than the previous components. Livermore's Laboratory Directed Research and Development Program supported the basic research and development on the solid-state modulator technology, and SLAC supported the systems integration.

Download or read book The Development of the Next Linear Collider at SLAC. written by and published by . This book was released on 1992 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: At SLAC, we are pursuing the design of a Next Linear Collider (NLC) which would begin with a center-of-mass energy of 0.5 TeV and be upgradable to at least 1.0 TeV, and possibly 1.5 TeV. The luminosity is designed to be 1033 cm−2s−1 at the lower energy and 1034 cm−2s−1 at the top energy. In this paper, we discuss the accelerator physics issues which are important in our approach, and also the present state of the technology development. We also review the impact that the SLC has had in the evolution of our basic approach.

This book was released on 1995-05-04 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physics research relies increasingly on the use of large facilities. The construction and operation of these facilities represent an increasing fraction of the funding for research. The most often calls for international collaborations. Since large facilities are now of great importance in all domains of physics, it is instructive to consider them in parallel. This is what is done in this book which puts emphasis on large physics facilities in Europe whilst taking a worldwide perspective.

Book Synopsis Research and Development for an X-Band Linear Collider by :
Download or read book Research and Development for an X-Band Linear Collider written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At SLAC and KEK research is advancing toward a design for an electron-positron linear collider based on X-Band (11.4 GHz) rf accelerator technology. The nominal acceleration gradient in its main linacs will be about four times that in the Stanford Linear Collider (SLC). The design targets a 1.0 TeV center-of-mass energy but envisions initial operation at 0.5 TeV and allows for expansion to 1.5 TeV. A 1034 cm-2s-1 luminosity level will be achieved by colliding multiple bunches per pulse with bunch emittances about two orders of magnitude smaller than those in the SLC. The key components needed to realize such a collider are under development at SLAC and KEK. In this paper we review recent progress in the development of the linac rf system and discuss future R & D.

Book excerpt: The NLC/JLC collaboration focuses its major effort on X-band linac technology which is the main part of a 1 TeV electron-positron linear collider. Both SLAC and KEK have pursued R & D for a TeV linear collider over 15 years with the acronyms NLC (Next Linear Collider) and JLC (Japan Linear Collider). The two teams assumed X-band (11.424 GHz) warm linac technology for the main linac, although R & D for technology at C-band (5.712 GHz) has also been optionally undertaken at KEK. The collaboration between SLAC and KEK is focused on the X-band linac technology and low-emittance beam generation study [1] at the ATF (Accelerator Test Facility) damping ring of KEK. In this collaborative framework, however, many other laboratories have also contributed: BINP (Protvino, Russia), Postech (Korea), IHEP and Tsinghua University (Beijing), LLNL, LBNL and recently FNAL (USA), and several universities worldwide. Since 1998, 8 meetings have been held for the International Study Group (ISG), through which NLC and JLC are getting much closer in the design features and R & D directions. The report below summarizes is the recent R & D status on X-band accelerating structures and RF power source together with some interesting results of the most-up-to-date beam monitors developed at the ATF damping ring.
