DAQ
- Beni: testing the latest fADC125 firmware released, works except something goes wrong in the FPGA when setting event number. ROCFDC3 has problems will be excluded for the next run. We want to take data with the magnet on. The top scintillator paddle was moved as high as possible to reduce the filed on the PMTs. Actually, after the meeting Beni and Elton were able to get signals from the scintillator (after increasing the HV) and started the DAQ (FDC+CDC) with the considence trigger.
- Discussions about horizontal trigger. We need to install it back. The upstream paddles can be installed when the traget is out. Instead of the downstream paddles one can use the TOF, but it requires the GTP.
CDC update
- Mike:
