Abstract

Results from a prototype high-pressure xenon gas scintillation drift chamber using a novel wave-shifter fiber readout scheme are presented. The primary scintillation light yield was measured to be one photon per 76±12 eV deposited energy. Initial results on the chamber are presented for two-interaction separation (<4 mm in the drift direction, ~7 mm orthogonal to the drift); for position resolution (<400 μm RMS in the plane orthogonal to the drift direction); and for energy resolution (δE/E<6% FWHM (full width at half maximum) at 122 keV)
