Description

A 1.5-m linac is being installed at the hybrid gun’s beamline in UCLA Mithra Laboratory for the advanced accelerator research. A preliminary experiment by using a steering magnet showed the electron beam was accelerated from 4 MeV to greater than 30 MeV. A more precise measurement of the beam energy with a new spectrometer magnet is planned in early 2025 as well as the beam emittance. The electro-optic sampling (EOS) experiment is under design for a coarse single-shot bunch length measurement for tuning the beam, while interferometry of the coherent transition radiation (CTR) from a metal foil is ready for the precision measurement of the length for the compressed bunch. For the application of the beam, the generation of coherent cherenkov radiation (CCR) at sub-THz in a hollow dielectric tube is being prepared. The detailed designs and results will be discussed on the spot.
