HRRL run on March 22-26 2010

Preliminary setup

3/17/10

Install detector infrastructure to mount 2 Drift chambers, 2 Scintillators and 1 GEM on a translator table.

Install collimation

3/18/10

Install all detectors and associated electronics (power supplies, cabling, gas lines,...)

Timing concept

There are 3 modules to be readout; an ADC, a TDC, and the V1495.

The ADC requires a gate defining the integration interval of the pulse. The TDC requires a start pulse to begin the TDC clock and a stop pulse to stop the TDC clock. The V1495 requires a trigger pulse to tell it there is data coming from the VFATs.

The ADC and TDC will be run so they get pulses every time there is a RF pulse. The data are only recorded though if there is a coincidence pulse telling them to keep the data. Otherewise the ADC and TDC will throw the data away.

3/19/10

install DAQ system and associated readout electronics.

Check channels in histograms


Coincidence: Coincidence between Accelerator's RF pulse generator, and several PMTs

TDC start: Accelerator RF pulse generator. TDC stop: 2 DC, 1 GEM trigout, 4 PMTs

ADC: all FC channels from Accelerator ribbon cable. ADC gate: Create timing gate using scope when accelerator

V1495: Trigger pulse from coincidence logic above

3/22/10

Final day for completing system checks

3/23/10

1pm - 5pm: Tune beam for low and high current

3/24/10

Positron spectrometer run plan

Detector tracking run plan
