  6. Electroluminescenceyieldinmicropatterndevices • Goodagreement • withformer • simulationwork • experimental data F.P. Santos et al., J. Appl. Phys. 27 (1994) 42 C.M.B. Monteiro et al., JINST 2 (2007) P05001 BERKELEY, NOV 09 WORKSHOP ON XENON BASED DETECTORS JMF dos Santos

  7. Electroluminescenceyieldinmicropatterndevices • Similar behavior as experimenta data • Smalldifferences are beingstudied BERKELEY, NOV 09 WORKSHOP ON XENON BASED DETECTORS JMF dos Santos

  8. A simulation tool based on Magboltz / Garfield was developed to follow excited states produced in gas avalanches • Y was accessed in GEM (same behaviour as experimental data) • Nexc increases with p • Ne • Nexc>> Ne ( 1 order of magnitude) • -> Light is an addicional information which can be usefull • VUV fluctuations are not higher than charge fluctuations Electroluminescenceyieldinmicropatterndevices BERKELEY, NOV 09 WORKSHOP ON XENON BASED DETECTORS JMF dos Santos

  9. Charging-up in dielectric surface • Upgrade of Xe x-sections file is under development • (upto 24 different excited levels) • Other properties will be accessed • Light position distribution (isotropic emittion, atoms diffusion) • Light signal (cascade radiative decay processes between states) • Gas mixtures (Penning tranfers, . . . ) • Include B-field • Use neBEM • Interfacing with GEANT4 Electroluminescenceyieldinmicropatterndevices(Futurework) BERKELEY, NOV 09 WORKSHOP ON XENON BASED DETECTORS JMF dos Santos
