Abstract
A THz-pulse-train photoinjector employs a THz-pulse-train laser as its driver laser to generate an electron macro-pulse containing THz micro-bunches. We propose to compress the electron macro-pulse in a linac through velocity bunching to multiply its bunching frequency. Our study shows the bunching spectrum extends to a few tens of the harmonics of the initial micro-bunching frequency. Copyright © 2011 by IPAC'11/EPS-AG.
