摘要

Measurement of emittance for a space-charge dominated electron beam from a photocathode rf gun is performed by employing the multislit-based method at Accelerator Laboratory of Tsinghua University.We present the design considerations on the multislit system and the experimental results,with special attention to the study of space charge induced emittance growth.The experimental results are in reasonable agreement with the PARMELA simulations.
