Review of linear colliders in the framework of future world accelerators

The HEP communities in three major regions, Asia, Europe and North America, have recently agreed that experimental particle physics in the next twenty years will be greatly enriched if an e + e − linear collider were to be available in the TeV c.m. energy range to supplement the opportunities offered by the LHC. This abridged paper of a longer oral presentation at ICHEP 2002 outlines several current design options for such an e + e − linear collider, which are presently under intense study by the International Linear Collider Technical Review Committee (ILC-TRC).

Production of high power microwaves for particle acceleration with an FEL bunched electron beam

Among the studies in the framework of high gradient linear electron–positron collider research, the Two-Beam Accelerator (TBA) is a very promising concept, and two projects are in progress, the Compact Linear Collider project at CERN (W. Schnell, Report no. CERN SL/92-51 and CLIC note 184; K. Hübner, CERN/PS 92-43, CLIC note 176; S. Van der Meer, CERN/PS 89-50, CLIC note 97.) and the Relativistic Klystron-TBA project at LBNL (Technical Review Committee, International Linear Collider Technical Review Committee Report 1995, SLAC-R-95-471, 1995). In a TBA an extremely intense low-energy electron beam, called the drive beam, is bunched at the desired operating frequency, and upon passing through resonant cavities generates radio-frequency power for accelerating the main beam. Among the different approaches to the production of a suitable drive beam, the use of an FEL has been proposed and is under active study at CEA/CESTA.
