A High-duty 1.6 Cell s-Band RF Gun Driven By a psec Nd:YAG Laser
نویسندگان
چکیده
The performance tests were done for a 1.6 cell s-band BNL-type photocathode RF electron gun, GUN-IV, under a condition of 1.5MW RF power input and 266nm Nd:YAG laser pulse irradiation. As a result, the maximum energy and the maximum charge/ bunch were obtained as 1.6 MeV and 120 pC/bunch, respectively. In addition, a sinusoidal behavior of current with the polarization angle of laser light were measured. Furthermore, the change in current as a function of laser injection phase was measured and reasonably reproduced by a numerical calculation.

Emittance and Quantum Efficiency Measurements from a 1.6 cell S- Band Photocathode RF Gun with Mg Cathode
A comparison of electron beam parameters from a 1.6 cell S-band rf gun with Cu and Mg cathode at the SLAC Gun Test Facility are reported. The lower work function of Mg compared to Cu theoretically increases the quantum efficiency for a fixed laser wavelength and also increases the thermal emittance. Slice emittance measurements at low charge (15 pC) set an upper limit on the thermal emittance o...

A 1.6 cell photocathode S-Band gun developed by the BNL/SLAC/UCLA collaboration is now in operation at the Brookhaven Accelerator Test Facility (ATF). One of the main features of this RF gun is the symmetrization of the RF coupling iris with a identical vacuum pumping port located in the full cell. The effects of the asymmetry caused by the RF coupling iris were experimentally investigated by p...
متن کاملRf Design for the Linac Coherent Light Source (lcls) Injector*
The Linac Coherent Light Source (LCLS) will be the world’s first x-ray free electron laser, and the successful operation of this very shortwavelength FEL will require excellent beam quality from its electron source. Therefore a critical component is the RF photocathode injector. This paper describes the design issues of the LCLS RF gun and accelerator structures. The injector consists of a 1.6 ...

The Gun Test Facility (GTF) consists of a 1.6-cell S-band photocathode gun and a single SLAC 3-m accelerating structure (booster) followed by a beam dump. The beam components are housed in the SPEAR synchrotron injector vault in Building 140. Outside the vault are the two XK5 klystrons/modulators that provide the rf power, and the laser shack and control area. The laser shack contains a high-po...
