“…Regarding the RF power needed, for 100 MW of total beam power at 7.2 mA per beam with 580 cavities, a continuous power of 172 kW per cavity will be required. 1.3 GHz klystrons are currently available for pulsed operation at up to about 150 kW average power [37] [38], and further design work will be required to produce a klystron for continuous wave operation above this power level. One area where current technology is not adequate is in the power couplers, where L-band coupler designs are currently limited to continuous power levels of around 60 kW [39].…”

A strong candidate for the Standard Model Scalar boson, H(126), has been discovered by the Large Hadron Collider (LHC) experiments. In order to study this fundamental particle with unprecedented precision, and to perform precision tests of the closure of the Standard Model, we investigate the possibilities offered by an e + e − storage ring collider. We use a design inspired by the B-factories, taking into account the performance achieved at LEP2, and imposing a synchrotron radiation power limit of 100 MW. At the most relevant centre-of-mass energy of 240 GeV, near-constant luminosities of 10 34 cm -2 s -1 are possible in up to four collision points for a ring of 27km circumference. The achievable luminosity increases with the bending radius, and for 80km circumference, a luminosity of 5 10 34 cm -2 s -1 in four collision points appears feasible. Beamstrahlung becomes relevant at these high luminosities, leading to a design requirement of large momentum acceptance both in the accelerating system and in the optics. The larger machine could reach the top quark threshold, would yield luminosities per interaction point of 10 36 cm -2 s -1 at the Z pole (91 GeV) and 2 10 35 cm -2 s -1 at the W pair production threshold (80 GeV per beam). The energy spread is reduced in the larger ring with respect to what is was at LEP, giving confidence that beam polarization for energy calibration purposes should be available up to the W pair threshold. The capabilities in term of physics performance are outlined.

“…In addition to the multiple beam klystrons (MBK) developed by Thales [1], CPI [2], and Toshiba [3], several alternative klystron designs have also been proposed. SLAC has been working on a sheet-beam klystron design, as well as an alternative PPM-focused round-beam klystron [3].…”

FAR-TECH, Inc. is developing and building a 36 kV, 830 kW klystron for the International Linear Collider (ILC) testing program. A variant of the tube can also be used to supply RF energy for a 2 or 3 meter section of ILC. The tube design is of the multiple-beam klystron (MBK) type, using ten beams with confined flow focusing. The design optimizes small tube size and low cost. The initial prototype will use an electromagnet, but the design allows for the eventual use of a permanent magnet solenoid. An efficiency of 65% is expected. We will present the design and status of the construction of the klystron and supporting systems.
