Absorption of scintillation light in a 100 l liquid xenon γ-ray detector and expected detector performance
چکیده انگلیسی
An 800 l liquid xenon scintillation γ-ray detector is being developed for the MEG experiment which will search for μ+→e+γ decay at the Paul Scherrer Institut. Absorption of scintillation light of xenon by impurities might possibly limit the performance of such a detector. We used a 100 l prototype with an active volume of 372×372×496mm3 to study the scintillation light absorption. We have developed a method to evaluate the light absorption, separately from elastic scattering of light, by measuring cosmic rays and α sources. By using a suitable purification technique, an absorption length longer than 100 cm has been achieved. The effects of the light absorption on the energy resolution are estimated by Monte Carlo simulation.
