Acceleration of Electrons in a Diffraction Dominated IFEL / Musumeci, Pietro ; Joshi, Chandrashekhar ; Pellegrini, Claudio ; Ralph, J ; Rosenzweig, J B ; Sung, C ; Tochitsky, Sergei Ya ; Travish, Gil
We report on the observation of energy gain in excess of 20 MeV at the Inverse Free Electron Laser Accelerator experiment at the Neptune Laboratory at UCLA. A 14.5 MeV electron beam is injected ina 50 cm long undulator strongly tapered both in period and field amplitude. [...]

Investigation of X-Ray Harmonics in the Polarized Nonlinear Inverse Compton Scattering Experiment at UCLA / Doyuran, Adnan ; England, Robert J ; Joshi, Chandrashekhar ; Lim, Jae ; Rosenzweig, James E ; Tochitsky, Sergei Ya ; Travish, Gil ; Williams, Oliver
An Inverse Compton Scattering (ICS) experiment investigating the polarized harmonic production in the nonlinear regime has begun which will utilize the existing terawatt CO2 laser system and 15 MeV photoinjector in the Neptune Laboratory at UCLA. A major motivation for a source of high brightness polarized x-rays is the production of polarized positrons for use in future linear collider experiments. [...]

Terahertz IFEL/FEL Microbunching for Plasma Beatwave Accelerators / Sung, Chieh ; Clayton, Chris ; Joshi, Chandrashekhar ; Musumeci, Pietro ; Pellegrini, Claudio ; Ralph, Joseph ; Reiche, Sven ; Rosenzweig, James E ; Tochitsky, Sergei Ya
In order to obtain monoenergetic acceleration of electrons, phase-locked injection using electron microbunches shorter than the accelerating structure is necessary. For a laser-driven plasma beatwave accelerator experiment, we propose to microbunch the electrons by interaction with terahertz (THz) radiation in an undulator via two mechanisms– free electron laser (FEL) and inverse free electron laser (IFEL).

Production of Terahertz Seed Radiation for FEL/IFEL Microbunchers for Second Generation Plasma Beatwave Experiments at Neptune / Ralph, Joseph ; Joshi, Chandrashekhar ; Rosenzweig, James E ; Sung, Chieh ; Tochitsky, Sergei Ya
To achieve phase locked injection of short electron bunches in a plasma beatwave accelerator, the Neptune Laboratory will utilize microbunching in an FEL or IFEL system. These systems require terahertz (THz) seed radiation on the order of 10 kW for the FEL and 10 MW for the IFEL bunchers. [...]

Feasibility Study of a Laser Beat-Wave Seeded THz FEL at the Neptune Laboratory / Reiche, Sven ; Joshi, Chandrashekhar ; Pellegrini, Claudio ; Rosenzweig, James E ; Shvets, Gennady ; Tochitsky, Sergei Ya
Free-Electron Laser in the THz range can be used to generate high output power radiation or to modulate the electron beam longitudinally on the radiation wavelength scale. Microbunching on the scale of 1-5 THz is of particular importance for potential phase-locking of a modulated electron beam to a laser-driven plasma accelerating structure. [...]

High-gain Seeded FEL Amplifier Tunable in the Terahertz Range / Sung, C ; Joshi, C ; Pellegrini, C ; Ralph, J E ; Reiche, S ; Rosenzweig, J B ; Tochitsky, Sergei Ya
The lack of a high-power, relatively low-cost and compact terahertz (THz) source in the range 0.3-3x10(12) Hz is the major obstacle in progressing on biomedical and material studies at these wavelengths. A high-gain, single pass seeded FEL technique allows to obtain high power THz pulses of a high spectral brightness. [...]
