Updated flux estimates (for
InGaAs) [26-MAR-2011]:
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:
IRS/BLAB3 readout via (slow) copper link
ROE2 (fiber optic) readout
cPCI data logging
Implement long-term radiation production/loss monitoring
Test of 3D detector
Test of ATF2 readout module prior to commissioning
STURM2 based readout
MCP-PMT test
Silicon samples from SNF
Experiment 3 scheduled:
Oct. 20-21, 2010
Objectives:
Commission permanent monitoring diagnostics:
HPK PMT with scintillator (off axis) + amplifier for
background monitoring
Commission scintillator + PIN diode + amplifier for beam
intensity monitoring (x20dB, x40dB select?)
Full train readout ASIC (IRS_eval?)
Establish monitoring procedures for the long term
(integrated radiation, loss, etc)
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
