A time dependent solution for the operation of ion chambers in a high ionization background

We have derived a time dependent solution describing the development of space charge inside an ion chamber subjected to an externally caused ionization rate N. The solution enables the derivation of a formula that the operational parameters of the chamber must satisfy for saturation free operation. This formula contains a correction factor to account for the finite duration of the ionization rate N.

Beam Tests of Ionization Chambers for the NuMI Neutrino Beam

We have conducted tests at the Fermilab Booster of ionization chambers to be used as monitors of the NuMI neutrino beamline. The chambers were exposed to proton fluxes of up to 10$^{12}$ particles/cm$^2$/1.56$μ$s. We studied space charge effects which can reduce signal collection from the chambers at large charged particle beam intensities.
