Febetron pulse radiolysis

Almost all the work in pulse radiolysis is based on the use of three types of electron accelerators linear accelerators (linacs). Van de Graaff accelerators, and Febetrons. The first accelerator used by Keene at Manchester was a 4-MeV linac with pulses of 0.2-2 ps duration [47a] this was replaced in 1967 with an 8-12-MeV linac capable of delivering pulses from 5 ns to 5 ps duration [93]. Further improvements made to the Manchester system up to 1989 have been documented [93]. Similarly, the 13-MeV linac used at Argonne in 1960 by Matheson and Dorfman produced pulses of 0.4 to 5 ps duration [46], whereas in 1989 the equipment comprised a 20-MeV linac, capable of producing pulses from 25 ps to 10 ps duration, and a 3-MeV Van de Graaff accelerator, which is dedicated to EPR and magnetic resonance studies (see below) [95, 98]. 

At this time possible transients have not been observed yet. Consequently monoelectronic oxidations have been carried out using pulse radiolysis technique (Febetron 708) and fast kinetics absorption spectrophotometry.
