“…A reflector foil to be measured is installed, forming the mantle of the active volume of ≈ 1.3 kg of liquid argon defined by an aluminium cylinder. The cylinder consists of a top ring holding the 241 Am α source for cryogenic liquids The 241 Am α source was prepared by means of the Molecular Plating technique [20], [21], [22]. Electrodeposition was performed from 241 Am nitrate solution in isopropyl alcohol using the cell shown in Fig.…”

The detection of VUV scintillation light, e.g. in (liquid) argon detectors, commonly includes a reflector with a fluorescent coating, converting UV photons to visible light. The light yield of these detectors depends directly on the conversion efficiency. Several coating/reflector combinations were produced using VM2000, a specular reflecting multi layer polymer, and Tetratex R a diffuse reflecting PTFE fabric, as reflector foils. The light yield of these coatings was optimised and has been measured in a dedicated liquid argon setup built at the University of Zurich. It employs a small, 1.3 kg LAr cell viewed by a 3-inch, low radioactivity PMT of type R11065-10 from Hamamatsu. The cryogenic stability of these coatings was additionally studied. The optimum reflector/coating combination was found to be Tetratex R dip coated with Tetraphenyl-butadiene with a thickness of 0.9 mg/cm 2 resulting in a 3.6 times higher light yield compared to uncoated VM2000. Its performance was stable in long term measurements, ran up to 100 days, in liquid argon. This coated reflector was further investigated concerning radioactive impurities found to be suitable for current and upcoming low-background experiments. Therefore it is used for the liquid argon veto in Phase II of the GERDA neutrinoless double beta decay experiment.

“…The downside, of course, is the larger amount of target material needed. Promising results regarding an improvement of the current technology have been achieved with intermetallic targets 10 , which represent a better alternative in comparison to targets prepared by molecular electroplating. However, considerable efforts are need before such a technology finds broad application in SHE synthesis experiments.…”
