Abstract :
We describe the performance of a multiwire proportional chamber filled with Xenon (93% Xe, 7% C02) to a pressure of 60 psi absolute. The readout is by the electromagnetic delay line method. Measurements taken at 60 keV and 140 keV show that 1 mm and 2 mm lead grid patterns can be resolved. MTF curves are given for both these energies and the projected performance for clinical work with 99Tc is described.
