Review of minutes from the last meeting

We went over the minutes from the meeting on February 9th without significant comment.

TOF II Trigger

Beni reported that Sascha Somov has not had a chance to test the trigger yet.


Beni installed our spare CAEN TDC into the TOF crate for the downstream scintillator paddles used by CPP. When his standalone read-out program failed, he found that the firmware needed upgrade. He contacted Greg Kibilko to get a copy of the new firmware and Sergey Furletov downloaded it to the TDC yesterday. He is now taking data to adjust the least-count-equalizing resistors. After that he wants to do a integral non-linearity calibration on the board.

Paul asked Sasha O. to check the version of the firmware on the CAEN TDC they have at FSU. During CPP, with the JLab spare in the Hall, the FSU unit is the designated spare.

TOF NIM paper

Beni will review the section on walk corrections. There have been several iterations of the method over the years.
