Announcements
This was the first dedicated Start Counter Meeting, as announced earlier. Nominally we will meet every other Thursday at 3:30 pm.
Prototype Status
Werner and Lei reported on several items.
- Werner is leaning toward read-out with SiPM's, especially in light of the decision to go ahead and use them on the BCAL.
- We need to check that the radiation dose upstream of the target but close to the beam line is operationally acceptable.
- Werner has one at FIU to look at.
- New scintillator material has arrived at FIU.
- Light output of the new counters will be evaluated with the SiPM.
- Bending studies are proceeding. The plan is to measure light output before and after bending on an older 5 mm counter.
personnel erik pooser working on the prototype hardware studies • bending studies undergraduate, learning polishing • working on test stand to measure light output
lei: talking to company that made light guides for central tof of clas12 company not a detector, acrylic furniture, vitale found them, can bend and polish light guides no problem for straight, scintillator, bent scintillator will find out, a sample sent need to find out radiation dose upstream of target 40 element detector in $200 in material, 10k$, 40 sipms plus light guides support structure we will start on mou
