Plasma Panel Sensor – Tel-Aviv September

The Tel-Aviv University team Professor Erez Etzion Dr. Yan Ben-Hammou Meny Ben-Moshe Nir Guttman Yiftah Silver

15 years of detectors R&D for High energy physics and the LHC Testing the TGCs for the ATLAS experiment Testing and developing the STGC for the ATLAS upgrade The lab is currently under construction, moving into a bigger room to better accommodate the test-bench, gas system, electronics etc. 9/27/2012Tel Aviv University

Experiment setup 9/27/2012Tel Aviv University4 Each RO line is X100 Attenuated and 100Ω terminated 10 μm position precision of collimated source Discriminator 10 RO lines VME V560 counter HV line quenched with 20MΩ connected to a 1MΩ /100MΩ voltage divider

Source position 9/27/20125 Source sits here 1cm thick, Delrin collimator, with a 3 mm slit opening Tel Aviv University

14 hour measurement collimated Source was left on the same position (above RO channel 7) for ~14 hours. 9/27/20126Tel Aviv University

Position scan Each full turn of the micrometer moves the source by 1mm Started the scan when the micrometer read is 60mm Made 16 measurements each of 5minutes and 1mm apart. CF4 gas, 600 Torr, 2316V. 9/27/20128Tel Aviv University
