Abstract

We present results from a prototype high pressure xenon gas scintillation drift chamber using a novel wave-shifter fiber readout scheme. We have operated the chamber at pressures as high as 20 atmospheres and have determined that the secondary light yield is linear in both reduced field and pressure. We have measured the primary scintillation light yield to be one photon per 76±12 eV deposited energy. We present initial results of our chamber for the two-interaction separation (<4 mm in the drift direction, mm orthogonal to the drift); for the position resolution (<400 gm rms in the plane orthogonal to the drift direction); and for the energy resolution (ΔE/E < 6% FVVHM at 122 keV).
