Kim, C H

Transverse and longitudinal beam dynamics in the ALS preinjector were simulated with a 2 1/2 D code. Strong space charge-forces at low energy and nonlinearities caused emittances to grow. However, careful tuning of the bunching system and the linac reduced emittance growth to an acceptable label. About 1/3 of the gun output are within the required energy spread and the normalized rms emittance is significantly lower than the expected value. 3 refs., 7 figs., 1 tab.
