Because it involves more accelerating structures with multiple RF frequencies and phase relationships, and a high-performance electron gun source to inject the electrons in about one nanosecond, a sub-harmonic pre-buncher adds a lot of cost and complexity of operation ofthe linac facility. Consequently, only a few pre-bunched picosecond linacs were built for pulse radiolysis studies. The first one was installed at Argonne National Laboratory in the 1970s [2] subsequently other picosecond installations were built at the University of Tokyo Nuclear Energy Research Laboratory (NERL) in Tokai-Mura [3,4] and Osaka University [4].Very recently, a new pre-bunched linacfor pulse radiolysis has been built at the Shanghai Institute of Applied Physics. 

Photocathode-based picosecond electron accelerators are conceptually simpler than pre-bunched thermionic systems, although they require reasonably powerful, multicomponent femtosecond or picosecond laser systems to drive the photocathode. In addition, the availability of synchronized laser pulses allows the development of advanced detection capabilities with unprecedented time resolution. The combination of ease of use and powerful detection methods has stimulated strong interest in photocathode gun systems. Since the installation ofthe first photocathode electron gun pulse radiolysis system at BNL [5,13], four additional photocathode-based facilities have become operational and two more are in progress. The operational centers include the ELYSE facility at the Universite de Paris-Sud XI in Orsay, France [7,8], NERL in Tokai-Mura, Japan [9,10], Osaka University [11,12], and Waseda University in Tokyo [13]. Facilities under development are located at the Technical University of Delft, the Netherlands, and the BARC in Mumbai, India.
