---+ GSI @ OCT %TOC% ---++ Aim 1 Charged studies. Done using: *2 chmbs + scint @ 90 degrees*. Real profile measured with TLD (1mm reso). 1 point to measure a 3D blob. Then finer studies. need to quantify the needed stat. 1 Charged studies VS angle. Done using: *2 chmbs + scint @ 90 degrees*. ---++ When? <a href="http://www.gsi.de/documents/DOC-2011-June-3-4.pdf" title="Beam time schedule">Beam time schedule</a> Starting from 12th October. Setting of cave takes ~ 2 days. Ends 16th October. * Everyone should leave th 10th of October * Someone should come back 15th Oct, someone after dismounting (18). ---+++ Tentative schedule 1 8-11 Mounting 1 11-13 Cave M setup 1 13-14 Beam time 1 ---++ Where Cave M. (Medical). Before 12 setting of the cave + quality check of the beam. ---++ Mechanics Rec with wheels. (dismounting) Table + arms to hold detectors. 1 One start counter BEFORE the phantom. 1 One arm should move in theta: New BM + LYso 1 One arm is on top of phantom: old chmb + BaF (or other fast scintillator) 1 One arm is fixed @ 90 degrees (collimator, BaF, veto) ---++ Hardware ---+++ Gas system Already @ GSI * Gas system. * %RED%Gas bottle (premixed 82/18 Ar Co2)%ENDCOLOR% Chambers fluxed in series. ---+++ Detectors Already @ GSI * 2mm Start counter or Daisy! * New Chmb * 1 (or 2) BaF scintillators * Collimator? * Veto? To be brought from Roma1 * Old Chamber+ cables. * New Start Counter read with two H10580 PMT, SC thickness: plexiglass 1,8 mm :: Aluminum foil 0,05 mm :: Black tape 0,25 mm * Lyso ---+++ Power supply Already @ GSI * LV power supply: 4 channels. (for the two chambers) To be brought from Roma1 * HV: any other needed channel. * HV: 4 channels. [3 channels for the two chambers.] Channels: * HV: * 3chs (New and OLd chmb) * 2chs (BaF) * 2chs HV * 1ch Start Counter GSI * 1ch veto * LV: * 4 channels (2 chambers) * 2 channels (Daisy) ---++ Electronics Already @ GSI * Crate Nim (ex FIRST trigger) * Crate VME * Scope (?) * Crate Camac (?) To be brought from Roma1 * Crate Camac * Crate Nim NIM Modules * Most of them are @ GSI: nim/ecl translators, discriminators.... * Nim/TTL translator (GSI) VME Modules * 3 QDC modules: 2 Roma1, 1 GSI * 2 TDC modules: 1190 + ? KLOE TDCs? GSI TDC? * I/O * Scaler *%RED%Delay modules?%ENDCOLOR%* Cables * 40 Lemo Cables (GSI) ---++ DAQ * %RED%Signal from TPS for Energy switch?%ENDCOLOR% * %RED%Bridged ACQ.<br />%ENDCOLOR% ---++ ELOG <a href="http://pcaen1.ing2.uniroma1.it:8060/gsioct11/" title="TB elog">The elog of the TB can be found here</a> ---++ Software @ CT : 30 min, 300 evt, 600 mum precision with 17*10^8 particles. ---+++ Acquisition Being developed on workstation2. Project is under svn. svn co svn+ssh://<youraccount>@pcaen1.ing2.uniroma1.it/home/sarti/SvnRepos/TestBeamCode/GsiOct_2011_Bridge ---+++ Decoding Being developed on workstation2. Project is under svn. svn co svn+ssh://<youraccount>@pcaen1.ing2.uniroma1.it/home/sarti/SvnRepos/TestBeamCode/GsiOct_2011_BridgeDecode ---+++ Configuration As of 13 Oct 2011 @ 15:00. QDC 1 QDC 1 (!Baf): Gate 500ns, Ch0 --> SC, Ch1 --> Palettino, Ch2 --> LYSO1, Ch3 --> LYSO2 1 QDC 0 (Baf1, Ex Multianode): Multianode 8 Ch (0,1 & 4-15) from P1, 58, 34, 26, 18, 10, 59, 51, 43, 35, 27, 19, 11, 3 Delayed by 8-900 ns. Ch2,3 delayed by 300ns (P50, P42). 1 QDC 2 (Bad2): Empty TDC 1 TDC 64 ch: 1 TDC 16 ch: 0--7 New Chmb. Ch 12 (sync signal). Ch 13: or of triggers. ---++ Strategy 1 ---++ Calibration of detectors * Lyso: should we calibrate? * BM: how much time do we need to have ST relations? Look at BTF.... to see if we can use the old ST without new calibration -- Main.AlessioSarti - 2011-09-20 * [[%ATTACHURL%/dessin_exp14102011.eps][dessin_exp14102011.eps]]: Experimental Setup * [[%ATTACHURL%/dessin_exp14102011.svg][dessin_exp14102011.svg]]: Experimental Setup * [[%ATTACHURL%/Gsi_Detectors.txt][Gsi_Detectors.txt]]: Cabling
