HV burn in
Begin burn in after at least 3 volume changes.
File:High Voltage Region 1 Sector 1 data.xls
Step 1: Set Voltage to 50 volts on all channels. Probe HVB to be sure that all sense, field, and guard wires have a voltage. (You should set current threshold to 10 microAmps on the HV supply)
Step 2: While monitoring the current, ramp the HV to the following
G:F:S= 525,-700,700
Step 3: Begin to take data recording the time and sense wire current as you ramp up the sense wire HV to 1400 volts while restricting the current draw to less than 10 micraAmps.
keep current under 10 micro amps while moving sense voltage up to 1400

Cosmic Runs

Cosmic rays were used to measure drift chamber time spectra with respect to scintillators placed above and below the drift chambers (more details are at the wiki location CLAS12R1_CosmicTestStand)

Cosmic measurements
Run # | Date | Description |
3806 | 1/10/13 | 3 hour cosmic run, 16 channels with leading edge discriminators (-80 mV, 100 ns pulse width) |
3809 | 1/10/13 | cosmic run on 1/10. Signal cable 4 (ch. 48-63). 16 channels with leading edge discriminators (-80 mV, 100 ns pulse width). |
3810 | 1/10/13 | cosmic run from 1/10 - 1/14. Signal cable 4 (ch. 48-63). 16 channels with leading edge discriminators (-80 mV, 100 ns pulse width). Scintillator paddle F1/F2 on table above Sector 1, paddle I1/I2 below. |
3811 | 1/10/13 | |
3831 | 2/1/13 | Changed disciminator from 80 mV to 60 mV, We improved the window, installed HV & STB boards, purged and started taking cosmic data again, DC is sandwhiched between 2 scints with PMTs aligned (PMT on only one end of Scint is turned on) |
3833 | 2/4/13 | Changed disciminator from 60 mV to 30 mV |
3834 | 2/11/13 | Changed disciminator from 30 mV to 60 mV |
3835 | 2/19/13 | Changed disciminator from 60 mV to 20 mV |

Runlist
Run # | Date | Description |
4008 | 4/11/13 | set ADB threshold to 100 , installed all 6 STB connectors, key was on the left as you face the ADC crate. Two top PMTs and one bottom PMT were in coincidence. The rate was about 0.5 Hz. at 9:41 on 4/12/13 I observed no voltage coming out of the discriminator monitor, the fuses were NOT blown. Hits seemed to disappear in the data. I recycled the ADB crate power and saw 100 mV on the discriminator monitor. Start a new run 40009 |
4009 | 4/12/13 | ADC threshold at 100 mV |
4014 | 4/16/13 | Removed cable from J10 connector on ADB crate and becan a cosmic run, the ROC & EB1 segfaulted after 57702 events |
4082 | 4/17/13 | first run with fully installed ADC crate & known map; ROC crashed after 5522 event around 20:53 |
4099 | 4/17/13 | ROC & EB crash after 4702 events, restarted all processes prior to taking this data |
4127 | 4/24/13 | ROC crashed because there was not enough memory for all the data, increased memory in the readoutlist R4127Histos |
After 500 -> 4000 events
