An Asset Test of the CLIC Accelerating Structure
نویسندگان
چکیده
Transverse wakefield suppression in the CLIC (Compact Linear Collider) multibunch accelerating structure, called the TDS (Tapered Damped Structure), is achieved primarily through heavy damping. In order to verify the performance of the TDS design and the validity of the theoretical tools used to model it, a 15 GHz version of the TDS has been constructed and tested in the ASSET facility at SLAC. The test has directly demonstrated transverse wakefield suppression of over a factor 100, with an excellent agreement between the measured and the calculated wakefield.

The Clic Main Linac Accelerating Structure
This paper outlines the RF design of the CLIC (Compact Linear Collider) 30 GHz main linac accelerating structure and gives the resulting longitudinal and transverse mode properties. The critical requirement for multibunch operation, that transverse wakefields be suppressed by two orders of magnitude within 0.7 ns (twenty fundamental mode cycles), has been demonstrated in a recent ASSET experime...

The main effects which limit accelerating gradient in CLIC (Compact Linear Collider) main linac accelerating structures are RF breakdown and pulsed surface heating. Recent highlights of the structure development program are presented, including demonstration of higher accelerating gradients using tungsten and a complete redesign of the CLIC main linac accelerating structure, based on reduced su...
متن کاملBeam-based Alignment of Clic Accelerating Structures Utilizing Their Octupole Component
Alignment of the accelerating structures is essential for emittance preservation in long linear accelerators such as the Compact Linear Collider (CLIC). The prototype structures for CLIC have four radial waveguides connected to each cell for damping wakefields and this four-fold symmetry is responsible for an octupole component of the radio-frequency fields, phase-shifted 90 degrees with respec...
متن کاملClic Test Facility Developments and Results
The objectives of the CLIC Test Facility (CTF) are to study the generation of short intense electron bunches using a laser driven photocathode in an RF gun, to generate 30 GHz RF power for high gradient tests of prototype CLIC components, and to test beam position monitors. The performance of the CTF has improved dramatically in the course of the past year and highlights are presented here. The...
متن کاملSLAC/CERN High Gradient Tests of an X-Band Accelerating Section
High frequency linear collider schemes envisage the use of rather high accelerating gradients: 50 to 100 MV/m for Xband and 80 MV/m for CLIC. Because these gradients are well above those commonly used in accelerators, high gradient studies of high frequency structures have been initiated and test facilities have been constructed at KEK [1], SLAC [2] and CERN [3]. The studies seek to demonstrate...
