20 January 2011R&D staf meeting - Jan T.1 Activities in 2010 at DESY test beam 4-chip/Ingrid tests in March; 3 days OK Single Ingrid tests in May combined with EUDET telescope: some synchro problems Single Ingrid tests in Aug/Sept with Bonnie Chow (DESY summer student); one run combined with ZEUS/MVD telescope; synchro seems OK, some problem with Endianness of various PCs (or software?) Octopuce (= 8 Ingrids) test on LP with magnet in December together with Saclay group

20 January 2011R&D staf meeting - Jan T.2 Track backscattering from chip (=anode) – quad-Ingrid detector

Handshaked Pixelman operation based on Uwe Renz Pixelman plugin Work performed with Uwe Renz (and Martin Killenberg support) and with DESY summerstudent Bonnie Chow Detector used is the (2009) single “8 um” Ingrid

20 January 2011R&D staf meeting - Jan T.4 Track scattering at grid (or anode) Beam entering through cathode Out-of-time track

20 January 2011R&D staf meeting - Jan T.5 DESY Nov/Dec test beam e- test beam 5 GeV Preparation/installation Octopuce detector in gastestbox on Monday 29/11 Some test runs in gastestbox w. beam on Tuesday 30/11 Mounting detector module on LPTPC evening Tuesday 30/11 Flushing with pure He and from morning Wed 1/12 with He/isoButane 80/20 (5-6 hours per 40l gas bottle at 9 bar when full) First data taking evening Thu 2/12 without B-field B = 1 T available from Fri 3/12 15:00 Several data taking runs until Sat 4/12 ~12:00 Data taking rather slow (1 Hz), because of only (old) PC that worked with Muros and 8-chips

20 January 2011R&D staf meeting - Jan T.6 8 Ingrids on daughter board LPTPC with 7 detector slots inside1 T solenoid

20 January 2011R&D staf meeting - Jan T.11 Summary (including some ‘old’ statements) 8 μ m thick Si 3 N 4 protection layers seem sufficient Problems with readout of 4-fold Timepix/Ingrid (still) being investigated Successful standalone “handshaked” operation with early shutter opening Common data acquisition with Zeus telescope, running EUDAQ, succeeded Short but rather successful data taking with Octopuce module at Large Prototype TPC at B = 0 and 1 T

20 January 2011R&D staf meeting - Jan T.12 Future Wafer-scale production of Ingrids/GEMgrids at IZM Berlin (all single steps of process tried out) Construct 2 nd Octopuce and test at LP with T2K gas Move to new (faster) readout: e.g. Muros/Pixelman  “Relaxed” Longer term (2(?) years): development of “full” scale LP module with ~64 – 119 Ingrids; integrated design Ingrid, cooling, FPGA readout and data transfer Timepix2 with better time resolution
