Experimental Demonstration of Wakefield Effects in a 250 GHz Planar Diamond Accelerating Structure

چکیده
We have directly measured the mm-wave wake fields induced by subpicosecond, intense relativistic electron bunches in a diamond loaded accelerating structure via the dielectric wake-field acceleration mechanism. Fields produced by a leading drive beam were used to accelerate a trailing witness electron bunch which followed the driving bunch at an adjustable distance. The energy change of the witness bunch as a function of its separation from the drive bunch is a direct measurement of the wake potential.

Design of a 30 Ghz Damped Detuned Accelerating Structure
Within the framework of the SLAC/CERN studies of 30 GHz linear colliders, an attempt has been made to scale as closely as possible the existing X-band NLC damped detuned accelerating structure to 30 GHz. A simple scaling was not possible because of mechanical and RF constraints. The 30 GHz design has 101 cells and a minimum aperture of 3.4 mm. In order to obtain acceptably small values for both...
متن کاملAn Asset Test of the CLIC Accelerating Structure
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....
متن کاملHigher Dipole Bands in the Nlc Accelerating Structure
We show that scattering matrix calculations for dipole modes between 23-43 GHz for the 206 cell detuned structure (DS) are consistent with finite element calculations and results of the uncoupled model. In particular, the rms sum wake for these bands is comparable to that of the first dipole band. We also show that for RDDS1 uncoupled wakefield calculations for higher bands are consistent with ...
متن کاملCommissioning and Recent Experimental Results at the Argonne Wakefield Accelerator Facility (AWA)
The commissioning of the upgraded AWA facility has been recently completed. The L-band electron gun has been fully commissioned and has been successfully operated with its Cesium Telluride photocathode at a gradient of 80 MV/m. Single bunches of up to 100 nC, and bunch trains of up to 32 bunches with a maximum total charge in the trains of 600 nC have been generated. Six pi-mode accelerating ca...

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...
