GSI @ OCT


Aim

  1. We are going to use silvio as target. Monoenergetic: 200/220 MeV/u. PMMA or poly for modeling... Transversal dimension?
  2. One arm: chamber + LYSO (charged particles flux + shape along z)
Changed:
<
<
  1. Other arm: Baf + collimator
>
>
  1. Other arm: Baf + collimator+ CMOS ?
 

When?

Starting from 9-14 May. Setting of cave takes ~ 1 day. We are going to have 1-2 shifts.

  • We start the 10th of May
  • We end the 15th May

Tentative schedule

  1. To be done.

Where

Cave A.

Before 10 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.
  2. One arm should move in theta: New BM + LYso
  3. One arm is fixed @ 90 degrees (collimator, BaF, veto)
Added:
>
>		Target
  1. 5x5x20 PMMA
  2. 20x20x20 PMMA
  3. Testa (silvio)

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

    • 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
Delay modules?

Cables

  • 40 Lemo Cables (GSI)

DAQ

  • Signal from TPS for Energy switch?
  • Bridged ACQ.

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

TDC

Strategy

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
