Next generation high brightness electron beams from ultrahigh field cryogenic rf photocathode sources

Journal Article Rosenzweig, J. B. ; Cahill, A. ; Dolgashev, V. ; ... - Physical Review Accelerators and Beams

Recent studies of the performance of radio-frequency (rf) copper cavities operated at cryogenic temperatures have shown a dramatic increase in the maximum achievable surface electric field. We propose to exploit this development to enable a new generation of photoinjectors operated at cryogenic temperatures that may attain, through enhancement of the launch field at the photocathode, a significant increase in five-dimensional electron beam brightness. We present detailed studies of the beam dynamics associated with such a system, by examining an S-band photoinjector operated at 250 MV / m peak electric field that reaches normalized emittances in the 40 nm-rad range atmore »« less

An ultra-compact x-ray free-electron laser

Journal Article Rosenzweig, J. B. ; Majernik, N. ; Robles, R. R. ; ... - New Journal of Physics

In the field of beam physics, two frontier topics have taken center stage due to their potential to enable new approaches to discovery in a wide swath of science. These areas are: advanced, high gradient acceleration techniques, and x-ray free electron lasers (XFELs). Further, there is intense interest in the marriage of these two fields, with the goal of producing a very compact XFEL. In this context, recent advances in high gradient radio-frequency cryogenic copper structure research have opened the door to the use of surface electric fields between 250 and 500 MV m^-1. Such an approach is foreseen tomore »« less

rf losses in a high gradient cryogenic copper cavity

Journal Article Cahill, A. D. ; Rosenzweig, J. B. ; Dolgashev, V. A. ; ... - Physical Review Accelerators and Beams

The development of high brightness electron sources can enable an increase in performance and reduction in size of extreme X-ray sources such as free electron lasers (FELs). A promising path to high brightness is through larger electric fields in radio-frequency (rf) photoinjectors. Recent experiments with 11.4 GHz copper accelerating cavities at cryogenic temperatures have demonstrated 500 MV / m surface electric fields with low rf breakdown rates. However, when the surface electric fields are larger than 300 MV / m, the measured cavity quality factor, Q₀, decreases during the input rf pulse by up to 30%, recovering before the nextmore »« less

Rb based alkali antimonide high quantum efficiency photocathodes for bright electron beam sources and photon detection applications

Journal Article Cultrera, L. ; Gulliford, C. ; Bartnik, A. ; ... - Journal of Applied Physics

In this paper, high quantum efficiency alkali antimonide photocathodes have been grown over both stainless steel and glass substrates using sequential evaporation of Sb, K, Rb, and Cs. Quantum efficiencies well above 25% have been measured at 400 nm. Finally, a bi-alkali Rb-K-Sb photocathode grown on a stainless steel substrate has been installed in a high voltage DC gun at Cornell University and the intrinsic electron beam emittance was measured at different photon energies.

Theory and simulation of high-brightness electron beam production from laser-irradiated photocathodes in the presence of dc and rf electric fields

Conference Jones, M E ; Peter, W

To take advantage of properties of laser-controlled photodiodes to produce electron beams, a new set of diode design criteria are needed. An analytical and numerical study of the geometrical and temporal factors that affect the design of high-brightness electron beams is presented. This study extends our previous work on this concept to include the effects of laser pulse shape, and emittance effects in the presence of rf fields. In general, the diode will not be space-charge limited. Therefore, the conventional Pierce electrode shapes are not appropriate. Furthermore, the finite temporal profile of the electron beams introduces a time-dependent space chargemore »« less
