Review minutes from previous meeting
We reviewed the minutes from the November 15th meeting.
FIU has found sufficient HV channels to get by for now. Another CAEN module is on order.
Counter shaping and polishing at McNeal
Eric went through an abridged version of the presentation he gave for the CEO of McNeal on recent experience with the scintillator. See his slides for details. He showed evidence for degradation of the attenuation length that is likely due to mishandling at McNeal.
Werner also points out that we should research how the heating and bending may affect scintillator long-term quality even if mechanical handling is done properly. He will talk to Eljen about this.
SiPM read-out status
- Eric mailed the broken ST-2 board to Fernando Barbosa. The gain measurement still needs to be done before Fernando finalizes all of the component values.
- Eugene reported that a shipment of SiPMs from Hamamatsu came in this week. Some of those can be used for more start counter read-out cards.
- FIU is installing a new version of CODA, version 3. They are getting help from David Abbott and things are going well.
- FIU could use a few more discrimintator channels. JLab will look into getting one of the new VME discriminators for them.
