XENON-100 Design Shield: - lead, 33T - polyethylene, 1.6T - copper, 2T Cryostat: - double walled (1.5 mm thick) - low r/activity stainless steel - total weight 70 kg Target: - 65 kg of LXe (total amount 170 kg) - 30 cm diameter, - 30 cm height Active veto: - 65 kg of LXe - 30 cm diameter, - 30 cm height Bell: - stainless steel - weight 3.6 kg PTFE structure: - 24 interlocking panels - enclose target volume - support field shaping rings - total weight of teflon 12 kg - UV light reflector 80 PMTs on the bottom, 98 PMT in the top array, 64 PMTs in the active veto Alexander Kish | XENON100 | 14th Geant4 Users Workshop | Catania, Sicily | October 15, 2009 | p.8
Simulation of the Optical Response Teflon reflection: added specular component upon the Lambertian shape. Set the surface to ‘dielectric-metal’ and ‘groundbackpainted’, in order to have full control on the parameters of the specular lobe Optical parameters: The electrode meshes are simulated as absorption discs -> good agreement with detailed azimuthal-averaged square mesh calculation Alexander Kish | XENON100 | 14th Geant4 Users Workshop | Catania, Sicily | October 15, 2009 | p.9
