Executive summary: thicker W wire boosts about factor of 33...   [PDF]   and thinner Al window definitely helps  [PDF]

Executive summary: even better -- going to a Be window!  [PDF]

Executive summary, He-filled beampipe helps somewhat...   [PDF]

Next items to be commissioned:
  1. IRS/BLAB3 readout via (slow) copper link
  2. ROE2 (fiber optic) readout
  3. cPCI data logging
  4. Implement long-term radiation production/loss monitoring
  5. Test of 3D detector
  6. Test of ATF2 readout module prior to commissioning
  7. STURM2 based readout
  8. MCP-PMT test
  9. Silicon samples from SNF

Experiment 3 scheduled:  Oct. 20-21, 2010

Objectives:
  1. Commission permanent monitoring diagnostics:
    1. HPK PMT with scintillator (off axis) + amplifier for background monitoring
    2. Commission scintillator + PIN diode + amplifier for beam intensity monitoring (x20dB, x40dB select?)
    3. Full train readout ASIC (IRS_eval?)
    4. Establish monitoring procedures for the long term (integrated radiation, loss, etc)
  2. Initial test of Fermionics (few channels?) with 60dB gain

Beam request:  all background monitoring can be done parasitic with other machine operations.  2x dedicated 5 minute bremsstrahlung target in runs

Experiment 2:  Sep 16, 2010    [page link]

TARGET_eval based DAQ, PMT+scintillator (background measurement), MPPC readout, PIN diode monitor
