Reduction of thermal emittance of rf guns
نویسندگان
چکیده
The transverse emittance from optimized rf photoinjectors is limited by the thermal emittance. The thermal emittance can be lowered by a factor >2 by using a semiconductor photocathode.

North-Holland, Amsterdam RF AND SPACE-CHARGE EFFECTS IN LASER-DRIVEN RF ELECTRON GUNS
Laser-driven rf electron guns [1] are potential sources of high-current, low-emittance, short bunch-length electron beams, which are required for many advanced accelerator applications, such as free electron lasers and injectors for high-energy machines. In such guns the design of which was pioneered at Los Alamos National Laboratory [1] and is currently being developed at several other laborat...
متن کاملSpace-charge effects in high brightness electron beam emittance measurements
The measurement of emittance in space-charge dominated, high brightness beam systems is investigated from conceptual, computational, and experimental viewpoints. As the self-field-induced collective motion in the low energy, high brightness beams emitted from photoinjector rf guns are more important in determining the macroscopic beam evolution than thermal spreads in transverse velocity; tradi...
متن کاملEfficient temporal shaping of electron distributions for high-brightness photoemission electron guns
To achieve the lowest emittance electron bunches from photoemission electron guns, it is essential to limit the uncorrelated emittance growth due to space charge forces acting on the bunch in the vicinity of the photocathode through appropriate temporal shaping of the optical pulses illuminating the photocathode. We present measurements of the temporal profile of electron bunches from a bulk cr...
متن کاملRf Focussing - an Instrument for Beam Quality Improvement in Superconducting Rf Guns
Rf electron guns require an external magnetic field focussing to produce a low emittance electron beam. A dc magnetic field focuses electrons in the beam already inside the cavity as they leave the photocathode. In superconducting rf guns (srf) the possibility of external magnetic focussing is quite limited. In this paper we investigate an effect of rf focussing in the first half cell of a 3+1/...
متن کاملOptical Properties of Cesium Telluride
Cesium telluride is the photoemissive material used in many laser-driven RF-guns like in TTF-FEL. The material has been already used since few years but a detailed study of its optical properties is still missing. In this paper, we present the measurements of the cesium telluride reflectivity versus wavelength and incidence angle. These measurements are used to calculate the real and complex pa...
