FEL R&D is being promoted dramatically as a light source technology and gradually develop into compact facility. FEL facility is usually operated with single bunch and has a high beam quality. In order to increase the average current intensity further, two bunch operation mode or multi-bunch operation mode is proposed to be applied to FEL facilities. Wakefield effect of multi-bunch operation...

CLIC is focusing on the Compact Linear Collider. This work is to make an alternative design for CLIC pulse compression scheme. Using a spherical cavity, the new design can offer a higher Q factor compared with a cylindrical cavity. Besides, the use of degenerated "Whispering Gallery" mode makes the mode launcher much smaller.

50. Design of high gradient LINAC with the new Gasket-Clamping technique and compact low pulsed heating couplers

Fabio Cardelli (INFN-LNF Frascati)

Recently, a new technique for the realization of high gradient accelerating structures, based on the use of special gaskets has been implemented for the realization of the new SPARC_LAB and ELI-NP RF guns.
They have been successfully tested at high power leading to new perspectives in the realization of high gradient structures. The new technique has been developed at the Laboratories of...

35. Simulation studies on the dielectric-loaded accelerating structures

Dr Yelong Wei (CERN)

A potential alternative to conventional disk-loaded copper structures is dielectric-loaded accelerating (DLA) structures, which comprises a simple geometry where a dielectric tube is surrounded by a conducting cylinder. The simplicity of the DLA structure offers a great advantage for RF-driven (> X-band) accelerating structures as compared with conventional metal structures which demand...
