ACCELERATOR PROJECTS WORLDWIDE
ACCELERATOR PROJECTS WORLDWIDE were discussed recently at a meeting in San Francisco. With electron-positron machines, for example, the future lies with linear accelerators, for which costs are proportional to the beam energy, as opposed to circular facilities, whose cost varies as the square of the energy. TeV-energy linear machines may not be available until next century, but design research proceeds at many labs: for the Next Linear Collider (NLC) at SLAC, the Japan Linear Collider (JLC) at KEK in Tokyo, the TeV Energy Superconducting Linear Accelerator (TESLA) at Cornell, and the CERN Linear Collider (CLIC) in Geneva. At LEP, plans are underway to double beam energies to 100 GeV in 1994 and to have polarized beams in 1996. HERA, the electron-proton collider under construction in Hamburg, will soon have 820-GeV protons, surpassing the energy of Fermilab's proton beams. The Fermilab Main Injector project seeks to boost the Tevatron's luminosity 25 times above present levels, the better to search for the top quark. (CERN Courier, August 1991.)

International Study Group (ISG) Meetings.
- The SLAC-KEK ISG was formed in 1998, based on a Memorandum of Understanding between SLAC and KEK on development of Linear Colliders, which utilizes room-temperature RF technologies for the main linacs. They are a series of SLAC-KEK International Linear Collider Study Group (ISG) Meetings.

International Collider Facility Pages:
Final Focus Test Beam
- The FFTB (SLAC) is a facility to investigate the factors which limit the size and stability of the beam at the collision point for a linear collider.
Accelerator Test Facility
- The ATF (KEK) is a program to experimentally confirm the feasibility of damping an electron beam for a linear collider. This facility is in Japan as part of the (J)LC Accelerator Research program.
NLC Test Accelerator
- The NLCTA (SLAC) is an accelerator facility to test X-band (11.424 GHz) accelerator sections, rf power compression, and beam loading compensation methods.
