3. 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

4. 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

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

6. 14 hour measurement collimated Source was left on the same position (above RO channel 7) for ~14 hours. 9/27/20126Tel Aviv University

Source position measurement 9/27/201210 points in this graph are the Gaussian fit results Errors are σ/ √ (n-1) Numbers in the x-axis have no global meaning, simply the read of the micrometer and not the distance from any real point in space… The electrode pitch in this panel (10 electrodes per inch) is the slope of this line: 0.4 electrodes per mm… Tel Aviv University
