Optimization of isolated electron pulses in the picosecond range from a linear accelerator using a streak camera–TV diagnostic system
TLDR
In this article, the authors measured the width of the Cerenkov light pulse generated by the electron beam using a streak camera-TV camera-computer system, and showed that a broad energy spectrum for the electrons or improper focusing into a 270° bending magnet increased the pulse width after it had traversed the magnet.Abstract:
We describe the technique and the results of a measurement of the width of a fine structure pulse from our L‐band electron linear accelerator. The pulse width was measured by measuring the width of the Cerenkov light pulse generated by the electron beam using a streak camera–TV camera–computer system. With very low beam currents, a pulse width of 20 psec (FWHM) was measured, while at higher beam currents a pulse width of 27 psec was measured showing a space‐charge effect. In addition, a broad energy spectrum for the electrons or improper focusing into a 270° bending magnet was also shown to increase the pulse width of the beam after it had traversed the magnet.read more

Instrumentation for the Generation and Detection of Transient Species
TL;DR: In this article, the use of pulses of high energy electrons of a few microseconds duration for studying radiation chemical changes was described, in contrast to temperature and pressure jumps: in the latter case the system moves only a small way from equilibrium, the change in equilibrium position depends upon the temperature/pressure dependence of the thermodynamic properties of the equilibrium state, and no new species are involved.

A wide−time range pulse radiolysis system of picosecond time resolution
TL;DR: In this article, a stroboscopic pulse radiolysis system was described which detects the transient absorption generated by a 20 psec pulse from a 20 MeV linear accelerator, which was obtained by using, as the analyzing light, the short pulse of?erenkov light generated by the portion of the electron beam which passes through xenon.
