Design Studies for a High Current Bunching System for CLIC Test Facility (CTF3) Drive Beam
نویسنده
چکیده
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 effect into consideration. By using PARMELA, it is shown numerically that the bunching system can provide the bunches which properties satisfy the design requirement of CTF3. The 0.8 meter long TW buncher working at 2π

An Injector for the CLIC Test Facility (CTF3)
The CLIC Test Facility (CTF3) is an intermediate step to demonstrate the technical feasibility of the key concepts of the new RF power source for CLIC. CTF3 will use electron beams with an energy range adjustable from 170 MeV (3.5 A) to 380 MeV (with low current). The injector is based on a thermionic gun followed by a classical bunching system embedded in a long solenoidal field. As an alterna...
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 کاملCommissioning Status of the Decelerator Test Beam Line in Ctf3
The CLIC Test Facility (CTF3) at CERN was constructed by the CTF3 collaboration to study the feasibility of the concepts for a compact linear collider. The test beam line (TBL) recently added to the CTF3 machine was designed to study the CLIC decelerator beam dynamics and 12 GHz power production. The beam line consists of a FODO lattice with high precision BPM’s and quadrupoles on movers for pr...
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...
متن کاملBeam Dynamics Simulation for the Ctf3 Drive-beam Accelerator
A new CLIC Test Facility (CTF3) at CERN will serve to study the drive beam generation for the Compact Linear Collider (CLIC). CTF3 has to accelerate a 3.5A electron beam in almost fully-loaded structures. The pulse contains more than 2000 bunches, one in every second RF bucket, and has a length of more than one μs. Different options for the lattice of the drive-beam accelerator are presented, b...
