Issues
- Follow up on HallD dp variation
- Start counter 96 degree rotation in cabling or software space (Simon).
- Tentative plan of action: To turn off the low voltage to the SiPM bias for a few specific start counter paddles and take a 1-hour run where we can identify the physical location of these paddles using the tracking detectors.
- DIRC LED TDC missing (David Lawrence, Justin DIRC SiPM reference signal (Justin)
- Tentative plan of action: Since no spare inverter box is available, Chris Stanislav will investigate if a simple box can be built.
