Present: Werner Boeglin, Eugene Chudakov, Lei Guo, Mark Ito (chair), Simon Taylor, Beni Zihlmann
We had an informal discussion of various issues related to the start counter.
- Werner is going to test some 3x3 mm fibers for light guides
- Currently FIU is seeing 20 ns rise time from the 16 cell array.
- Werner is interested in getting another pre-amp for the SiPM*
- He is also interested in obtaining a Peltier element; he is hopeful that cooling the SiPM may help timing resolution.
- Mark will set up a conference call with Werner, Fernando Barbosa, and Yi Qiang to discuss the previous two items.
- Beni lent the FIU guys an Ortec constant fraction discriminator (physically handed it over) to see if that helps with timing resolution in their set-up.
- Puneet Khetarpal, an FIU post-doc, might be able to start working on the start counter project part-time. His main responsibilities are in Hall B.
- The MOU between FIU and JLab will be circulated next week among Hall D staff for comment.
