1. Faculty of Physics, University of Belgrade General meeting, 19 th of May, 2015. Pixel/Connectors Checking Jovan Puzović, Faculty of Physics, Belgrade

2. Faculty of Physics, University of Belgrade General meeting, 19.05.2015. Page 2 out of 7 Jovan Puzović, Belgrade SHINE team Status - Start working on Sunday with some preparation works -Monday – Zoltan produce Mickey Mouse system to measure position in the cable where it is broken (by using delay between signal from signal generator and reflected signal) -All tested connections show delay of ~250/2 ns (~25m), the position of the break is in the TPC hut! -Monday afternoon we got access to experimental area!

3. Faculty of Physics, University of Belgrade General meeting, 19.05.2015. Page 3 out of 7 Jovan Puzović, Belgrade SHINE team Status -Fully checked 40 out of 96 bad pixels -20 has good connection – bad PMT/Scint. -7 not connected to the patch panel in TPC hut -8 connected, but PMT divider is broken -3 (+7?) bad connections between two patch panels -2 unclear at the moment -It seems that at least 35 out of 40 pixels has problem with PMT/Scintilators (or HV, or readout electronics)

4. Faculty of Physics, University of Belgrade General meeting, 19.05.2015. Page 4 out of 7 Jovan Puzović, Belgrade SHINE team Plan for Tomorrow -Check the rest of the pixels/connections -Open one of the cassette to inspect the situation with PMT, divider and scintilator
