Observation of a Remarkable Deflection of Multi-GeV Electron Beams by a Thin Crystal
Wienands, Ulrich.
We report on an experiment performing channeling and volume reflection
of a high-energy electron beam using a quasimosaic Si(111) crystal at
the ESTB at SLAC. The experiment used beams of 3.35~GeV and
6.3~GeV. In channeling orientation, deflections of the beam of 400~$\mu$rad with about 22\% efficiency were observed, while in volume-reflection orientation, deflection of the beam by 120~$\mu$rad at 3.35~GeV and by 80~$\mu$rad at 6.3~GeV was observed with $86-95$\% efficiency. Quantitative measure... Show Full Abstract

Quantitative measurements of
channeling efficiency, surface transmission and dechanneling length
were taken. These are the first quantitative measurements of channeling and volume reflection using a primary beam of multi-GeV electrons. Show Partial Abstract
