Paper Abstract

A novel subpicosecond pulse radiolysis experimental system has been developed in Terawatt Ultrafast High Field Facility (TUHFF) at Argonne National Laboratory. TUHFF houses a 20 TW Ti:sapphire laser system that generates 2.5 nC sub-picosecond pulses of 4-25 MeV electrons at 10 Hz using laser wakefield acceleration. The system has been optimized for chemical studies. The subpicosecond electron pulses were used to generate hydrated electrons in pulse radiolysis of liquid water. Preliminary transient absorption spectroscopy data with picosecond resolution is presented.
