Description
Joint session between working groups 3 & 5:
WG3 - Laser and High-Gradient Structure-Based Acceleration
WG5 - Beam Sources, Monitoring and Control
High brightness beams for XFELs and UEM essentially imply a high current and a low emittance. To obtain such beams we propose to raise the accelerating voltage in the gun mitigating repealing Coulomb forces. An ultra-high gradient is achieved utilizing a short-pulse technology. A successful experiment with an X-band photoinjector has been recently carried out at Argonne Wakefield Accelerator...
A program to develop a sub-GV/m rf photocathode gun is underway at Argonne Wakefield Accelerator (AWA) facility as a pathway towards producing brighter electron bunches. The X-band rf gun is powered by high-power, short rf pulses (9-ns FWHM), which, in turn, are generated by AWA’s high-current drive beam. In a previous proof-of-principle experiment, an unprecedented gradient of 400 MV/m on the...
We present the design of an experiment aiming at the generation of a moderate energy (4 MeV) single sub-fs electron beam from an RF photoinjector for application in UED and injection in advanced accelerators. The design is based on an envelope equation-based approach to obtain analytical scaling laws for the shortest pulse length achievable using radiofrequency (RF) based bunch compression....
