An iterative method was developed for in-situ reconstruction of the PMT light response functions from calibration data taken with an uncollimated γ -ray source, and the possibility of using this technique for improving performance and reducing cost of scintillation cameras for medical applications is currently under study.Abstract:
We studied the application of statistical reconstruction algorithms, namely maximum likelihood and least squares methods, to the problem of event reconstruction in a dual phase liquid xenon detector An iterative method was developed for in-situ reconstruction of the PMT light response functions from calibration data taken with an uncollimated γ -ray source Using the techniques described, the performance of the ZEPLIN-III dark matter detector was studied for 122 keV γ-rays For the inner part of the detector (R <; 100 mm) , spatial resolutions of 13 mm and 16 mm FWHM were measured in the horizontal plane for primary and secondary scintillation, respectively An energy resolution of 81% FWHM was achieved at that energy The possibility of using this technique for improving performance and reducing cost of scintillation cameras for medical applications is currently under studyread more

TL;DR: This new analysis incorporates several advances: single-photon calibration at the scintillation wavelength, improved event-reconstruction algorithms, a revised background model including events originating on the detector walls in an enlarged fiducial volume, and new calibrations from decays of an injected tritium β source and from kinematically constrained nuclear recoils down to 1.1 keV.
