The Next-generation Linear Collider The next-generation linear collider will require high-power microwave sources and accelerating systems vastly more challenging than its predecessor, the Stanford Linear Collider (SLC). Cost efficiency will demand high accelerating gradient to achieve beam energies five to ten times greater than in the SLC. Luminosity goals 10,000 times greater than the SLC demand efficient creation of the highest possible beam power without degradation of beam emittance. The past decade of R&D has demonstrated the feasibility of two technical approaches for building a 500-GeV center-of-mass system (cms) collider with attractive options for future upgrade. The TESLA R&D program offers the prospect of 1.3-GHz superconducting rf (srf) linacs with 23.4 MV/m gradient that can be upgraded later to 35 MV/m gradient by doubling the number of klystrons and the cryo-plant, to reach 800 GeV cms [1]. The Next Linear Collider (NLC) and Japanese Linear Collider (JLC) R&D programs offer the prospect of 11.4-GHz room-temperature linacs that can later be extended to 1 TeV by doubling the number of structures and klystrons, and to 1.5 TeV by additionally increasing gradient or length [2-4]. Both programs offer a 500-GeV linear collider project start within the next few years (2-3 years for TESLA, 3-4 years for NLC) based on available technology validated by experiments at several complementary test facilities. Both offer their upgrades as a result of further progress in R&D that is already underway. While both the 1.3-and 11.4-GHz approaches use klystrons to generate the accelerator rf power, a longer-range design study for a two-beam accelerator, the CERN Linear Collider (CLIC), is based on the concept of using klystrons to accelerate a low-energy drive beam that is subsequently compressed and de-accelerated to generate power at 30

“…In an attempt to circumvent these limitations, various concepts of active rf pulse compression have recently received attention, involving switches with optically-varied silicon mirrors [3], PIN/NIP diode arrays [4], and plasmas [5]. To date, none of the tested versions of these active pulse compressors achieved high enough power levels for use with NLC: the maximum output power achieved is 10 MW in the switch based on PIN/NIP diode array active window [6], and 50 MW in the compressor based on plasma switches [7].…”

“…Active rf pulse compressors are nowadays commanding interest for use in a future electron-positron collider [1,2]. In this paper, results are given from two campaigns during the first high-power experiments on a two-channel X-band active rf pulse compressor that employs gas discharge switch tubes as active elements.…”

“…Both channels function as active Bragg compressors (ABC), with synchronized input-output switchable reflectors. The detailed design of ABC [2] and low-power test measurements on it [3] have been reported previously. In the two-channel compressor scheme (ABC-2), the 3-dB hybrid coupler allows the input drive pulse from the magnicon to be split, with half the power directed to each channel.…”

Results are presented from experiments carried out at the NRL X-band magnicon facility on a two-channel X-band active rf pulse compressor that employs plasma switches. Evidence is shown to validate the basic goals of the project, which include: simultaneous firing of plasma switches in both channels of the rf circuit, operation at high power of a quasi-optical 3-dB hybrid directional coupler, coherent superposition of rf compressed pulses from both channels, and stable operation of the X-band magnicon directly into the resonant load presented by the rf pulse compressor. For incident 1.2-µsec pulses in the range 0.63-1.35 MW, compressed pulses of 5.7-11.3 MW were obtained in a first experimental campaign, corresponding to power gain ratios of 8.3-9.3. Following improvements in the experimental arrangement, 1.2-µsec pulses of 5.0 MW could be applied during a second campaign, yielding compressed pulses up to 53 MW peak power with power gain ratios up to 10.4.
