Design of a 3 Ghz Accelerator Structure for the Clic Test Facility (ctf 3) Drive Beam
For the CLIC two-beam scheme, a high-current, longpulse drive beam is required for RF power generation. Taking advantage of the 3 GHz klystrons available at the LEP injector once LEP stops, a 180 MeV electron accelerator is being constructed for a nominal beam current of 3.5 A and 1.5 Ps pulse length. The high current requires highly effective suppression of dipolar wakes. Two concepts are inve...
متن کاملTWO-FREQUENCY BEAM-LOADING COMPENSATION in the DRIVE- BEAM ACCELERATOR of the CLIC TEST FACILITY
The CLIC Test Facility (CTF) is a prototype two-beam accelerator, in which a high-current “drive beam” is used to generate the RF power for the main-beam accelerator. The drive-beam accelerator consists of two S-band structures which accelerate a bunch train with a total charge of 500 nC. The substantial beam loading is compensated by operating the two accelerating structures at 7.81 MHz above ...
متن کاملFirst Experimental Results with the Clic Drive Beam Phase Feedforward Prototype at the Clic Test Facility Ctf3∗
The two-beam acceleration scheme envisaged for CLIC will require a high degree of phase stability between two beams at the drive beam decelerator sections, to allow efficient acceleration of the main beam. There will be up to 48 such decelerator sections for the full 3 TeV design, and each decelerator section will be instrumented with a feed-forward system to correct the drive beam phase to a p...
متن کاملDesign Studies for a High Current Bunching System for CLIC Test Facility (CTF3) Drive Beam
A bunching system is proposed for the initial stage of CTF3 which consists of one (two) 3 GHz prebuncher(s) and one 3GHz travelling wave (TW) buncher with variable phase and group velocities. The electron beam is emitted from a 140 KV DC gun. Since the average macropulse beam current (3.5 A) at the exit of the TW buncher is rather high, inside the TW buncher one has to take the beam loading eff...
متن کاملDevelopment of a Beam Loss Detection System for the CLIC Test Facility 3
The CLIC test facility 3 (CTF3) provides a 3.5A, 1.6μs electron beam pulse of 150MeV at the end of the linac. The average beam power is 4 kW. Beam losses will be monitored all along the linac in order to keep the radiation level as low as possible. The heavy beam loading of the linac can lead to time transients of beam position, size and energy along the pulse. To compensate for these transient...
