Abstract

A proof of principle experiment is underway at the UCLA Neptune laboratory to test the concept of generating linearly ramped relativistic electron bunches (rising in density from head to tail followed by a sharp cutoff) by using a sextupole-corrected dogleg section as a bunch compressor. Bunches with this structure have been predicted to be ideal for use as a plasma wake-field drive beam. The diagnostic being developed to measure the time profile of the beam is an X-Band (9.6 GHz) deflecting cavity. The recently completed cavity is a 9-cell standing wave structure operating in a TM110-like mode, designed to measure the temporal structure of the 2 to 10 ps, 14 MeV electron bunches generated by the Neptune S-band photoinjector and plane-wave transformer (PWT) accelerator beamline, with 50 fs resolution. We discuss the experimental plan for the ramped bunch experiment and present preliminary data related to the tuning and operation of the deflecting cavity.

UCLA Neptune Ramped Electron Bunch Experiment

Journal Article England, R; Doyuran, A; Musumeci, P; ... - AIP Conference Proceedings

A ramped electron bunch (i.e. one having a current density which rises linearly from the head to the tail and then drops sharply to zero) has been predicted to be an ideal drive beam for the plasma wake field accelerator due to the large transformer ratio it is capable of generating. A scheme was recently proposed for the creation of a relativistic electron bunch that approximates a ramped current profile [England, et al., AIP Conf. Proc. 647, p.884 (2002)], using a dogleg or dispersionless translating section as a bunch compressor. An experiment is underway at the Neptune laboratory using thismore »« less

Seeded FEL Microbunching Experiments at the UCLA Neptune Laboratory

Journal Article Tochitsky, S; Musumeci, P; Rosenzweig, J; ... - AIP Conference Proceedings

Seeded high-gain FELs, which can generate very powerful radiation pulses in a relatively compact undulator and simultaneously modulate the electron beam longitudinally at the seed wavelength, are important tools for advanced accelerator development. A single-pass 0.5-9 THz FEL amplifier-buncher driven by a regular photoinjector is being built at the UCLA Neptune Laboratory. FEL interactions at 340 {mu}m (1 THz) are considered for the first experiment, since time-resolved measurements of longitudinal current distribution of the bunched beam using the RF deflecting cavity are possible. A design of a 0.2-2.0 {mu}m FEL using the same undulators is presented. In this case themore »« less

Plasmas source test and simulation results for the underdense plasma lens experiment at the UCLA Neptune Laboratory

Journal Article Suk, H; Clayton, C; Joshi, C; ... - IEEE Transactions on Plasma Science (Institute of Electrical and Electronics Engineers)

The planned plasma lens experiment at the UCLA Neptune Laboratory is described. In the experiment, electron beams with an energy of 16 MeV, a charge of 4 nC, and a pulse duration of 30 ps [full-width at half-maximum (FWHM)] are designed to be produced from the 1.625-cell photoinjector radio-frequency gun (f = 2.856 GHz) and PWT linac in the Neptune. The generated beams are passed through a thin underdense argon plasma with a density of low 10{sup 12} cm{sup {minus}3} range and a thickness of a few centimeters. For this experiment, a LaB{sub 6}-based discharge plasma source was developed andmore »« less

Electron Micro-Bunch Generation from RF Photoinjectors

Journal Article Serafini, L; Zhang, R; Pellegrini, C - AIP Conference Proceedings

In this paper we discuss how the injector specifications of a 2nd-generation plasma beat wave accelerator (PBWA) experiment can be achieved by a photo-injector. Typical required bunch lengths (FWHM) are 50 microns with 15 pC bunch charge. We analyze the possibility of generating such short electron bunches directly from a photoinjector by illuminating a photocathode in an RF electron gun with a phase-locked 160-fs laser pulse. In particular, we address all de-bunching effects taking place during acceleration and transport through the photo-injector. We provide a set of analytical scaling laws, as well as a comparison with detailed simulations of themore »« less

RF Design of the UCLA/INFN Hybrid SW/TW Photoinjector

Journal Article O'Shea, Brendan; Rosenzweig, James; Boni, Alessandro; ... - AIP Conference Proceedings

With increasing demand for high brightness, low emittance beams for use with free-electron lasers, Compton scattering systems and wake-field accelerator experiments, stringent requirements have been placed on the design and operation of the 1.6 cell photoinjector. The proposed hybrid photoinjector combines the BNL/UCLA/SLAC style 1.5/1.6 cell standing wave gun with a traveling wave accelerator. Our goal is an injector that meets today's requirements and is scalable in design to meet tomorrow's demands: emittances in the region of 1 mm-mrad for higher brightness as well as higher currents. The hybrid photoinjector also offers higher energy operation, enhanced cost effectiveness and bettermore »« less
