This document summarizes thickness and radiation length for materials crossed by incident and scattered electrons for Hall-A Polarized He experiments. Information listed here can be used for radiation effect caused by internal and external bremsstrahlung, and energy losses due to ionization for incident and scattered particles.
|glass||19.5||7.04||use GE180, 2.77 g/cm|
a. 1 mil=2.54 cm
b. depends on cell geometry
c. depends on target chamber density in beam, 1 amg=1.25 g/cm
d. depends on cell geometry
e. for E94010 it was 10 mil
f. density for gases are evaluated at 20 C, 1 atm
