Stability Analysis of the Laser System for the TTF Photoinjector at Fermilab
Abstract
Description
A solid-state laser system that produces a 1MHz pulse train of 800 pulses with 18 mJ per pulse at the wavelength of 263.5 nm has been developed to meet the requirements of the TESLA Test Facility (TTF) at Fermilab and in operation since 1998.[1,2] Besides the production of high charges, high brightness electron beams, the need for high bunch charge stability requires that each laser pulse in the pulse train must have the same energy, and the energy per laser pulse should not vary significantly from shot to shot. This motivates the stability analysis of the laser system for the TTF photoinjector.
