- Naomi got from Cody the firmware for self-triggering and will test it. Any channel above the threshold generates the trigger.

- Cody explained the self-triggering. He with Bryan's help checked it using testing set-up and it works. Naomi can't reproduce his result so far. The trigger is generated only within the module, so it can be used only for testing channels within the module, like when using 55Fe source. It can't be used with cosmics, for example. In the present version the readout can't go back in time w.r.t. trigger, but Beni suggested adding a constant delay to the trigger, which according to Cody can be easily implemented.

- Some issues with the gas system that happened when there was no CO2 supply have to be understood. The gas supply to the FDC mixing tank was bigger than the gas usage by the FDC. Beni performed a test and no leak was found between the mixing tank and the FDC. The techs found leakage in the check valves that were used just in this case to separate the empty gas bottles.

Minutes

Participants:Curtis, Naomi (CMU) Alex B., Marouen, Beni, Simon, Sergey, Cody, and Lubomir (JLab).

Collaboration meeting

- So far one slot in the tracking session (Mike's alignment), however it is not clear who wants to have a presentation. In principle we have short updates: CDC dE/dx amplitude vs integral (Naomi), dE/dx angular dependence (Lubomir), FDC efficiency (Alex A.), MC efforts, Simon's tracking modifications, FDC threshold upgrade. Naomi will decide how to organize the session.

CDC

- The plan is to start turning on the CDC systems and then do tests with cosmics. So far only the crates are on.

FDC

- The FDC chiller and LV system has been turned on (see [3]). Issues with the

fADC125

- Cody explained the self-triggering. He with Bryan's help checked it using testing set-up and it works. Naomi can't reproduce his result so far. The trigger is generated only within the module, so it can be used only for testing channels within the module, like when using 55Fe source. It can't be used with cosmics, for example. In the present version the readout can't go back in time w.r.t. trigger, but Beni suggested adding a constant delay to the trigger, which according to Cody can be easily implemented.

Other

- Next meeting after the collaboration meeting.
