Collection efficiency of an ionisation chamber in a pulsed swept beam: chamber size effects. 1986

J A Meli, and M S Weinhous

Boag's theory for the collection efficiency of a small ionisation chamber in a pulsed swept beam is generalised by taking chamber size into account. The collection efficiency is given in terms of the chamber radius, the Gaussian scale constant of the stationary beam, and the maximum distance between beam and chamber centres. It is shown that, for cases of practical interest, collection efficiency is independent of chamber size.
