---+ CNAO @ Jul 2012

<br />%TOC%
---++ Aim
   * Redo the Catania/GSI measurements on proton beam on PMMA target.
   * Several angles have to be tested: 90 deg, 60 deg, 75 deg
Beam structure. Spill to Spill 3-4 seconds. Spill lasts for 1 second. We are going to study that with the scope

Beam Energy: Computed by simulations (table from G. Battistoni is available)

---++ When?

July 20 - 22 .
   * July 20: mounting + first minutes of beam + calibration with source
   * July 21: 4 hours of beams... found that the SC are not behaving properly
   * July 21-22 night: 8 hours of datataking. First hourse devoted to SC replacement, then few hours at different angles/depths/energies.
Calibrations:
   * Lyso0 and Lyso1 have been calibrated with Co60 and Eu152
   * t0s for the chambers can be obtained by all the runs together....
---++ Where?

Hall 1. Control room 3m out of corridoio.

   * Patch Panel available to read signals in control room..
   * [[%ATTACHURL%/SKMBT_C36011101011350.pdf][SKMBT_C36011101011350.pdf]]: Sketch of halls and control rooms
   * [[%ATTACHURL%/isocentro1.pdf][isocentro1.pdf]]: Sketch of halls and control rooms
   * [[%ATTACHURL%/sezione.pdf][sezione.pdf]]: Sketch of halls and control rooms
---++ GAS

Ar/CO2
   * *%RED%We need to bring the premixed bottle%ENDCOLOR%*
   * Exhaust is ok.
---++ Mechanics

   * Rec for electronics? Arrived/mounted... We will bring it.
   * Needs to finalize the choice for the mechanical structure (we need to check how it goes with the angles study)
   * Need to know:
      1 beam height
Final setup (Catania like):
   1 Lyso + collim
   1 Two Nai at 180 degrees
   1 New Beam Monitor
---++ Hardware
   * New Beam monitor
   * 2 NaI detectors.
   * Collimator (slit)
   * 2 LYSO
   * Start Counter [we already have it]
   * Palettino before New Beam Monitor?
---++ ELOG

The <a href="http://arpg-serv.ing2.uniroma1.it/elog/cnaojul12/" title="Elog CNAO jul 2012 TB">elog</a>

---+++ Night btw 21/22 july.
   * Run: data/MainRun_2107_113mm_run1.dat : verify the impact of changes during the afternoon. A channel from drift chamber is recovered. SC continues to give troubles. Proceed at really low rate (100 Hz daq). Access at 23:40
   * Run: data/MainRun_2107_123mm_run2.dat : SC continues to give problems. But now rate is higher. Run 2 is taken at 132.72 MeV (123 mm) (113_run2 is a typo)
   * 2:14: intensity is higer, now the transmitted intensity is 50% (before was 20).
   * MainRun _2107_123mm_run4 --&gt; rate osservata e' 1kHz… --&gt; 321k events collected (Si e' spostato di 0.5mm in x positive…. banana plot seems to be worse (dirtier).)
   * Going back to *20 intensity (ridurre intensita'), we go @ 125mm run5
   * MainRun _2107_125mm_run5 started @ 2:49
   * MainRun _2107_121mm_run6 started @ 3:39
   * MainRun _2107_129mm_run7 started @ 4:25
   * MainRun _2107_117mm_run8 started @ 5:15
   * Si entra per rimetterci a 90deg

---++ DAQ

Checked that we can bring our WS1 for daq. There will be an ethernet connection from control room to hall: private network to connect to the WS1, and then we have a wireless to connect to outside. We will use a bridge for the acquisition (either usb or fiber).
---+++ DAQ config
   * TDC multihit ch 0-35: 36 tdc times from beam monitor
   * tdc and adc for the NaIs
   * Signals from machine?
   * RF or monitoring of position/energy
