round proton bunches in a round pipe
chamber radius 2 cm
20 bunches
bunch spacing 7.48 m
bunch population 1e11
rms bunch length 7.7 cm
(Gaussian profile, truncated at +/- 2 sqrt(3) sigma_z)
rms transverse beam
size 300 microns (Gaussian profile)
no magnetic field
primary electron
rate: 1e-3 per proton per meter launched uniformly (in azimuth) on the chamber
wall
true secondaries with delta_max=1.6, epsilon_max=250 eV
[OLD: fraction
of elastically reflected electrons given by Noel Hilleret's lower-energy fit
function f ]
NEW:
probability of elastic reflection given by quantum-mechanical fit
to Cimino-Collins data, with d(0)=1;
detailed description of
secondary emission model
result: electron line charge (total no. of e- per unit length) as a function
of time
