Time-of-Flight/Start-Counter Meeting, June 12, 2009
Minutes
FIU: Werner Boeglin
FSU: Sasha Ostridov
JLab: Mark Ito, Simon Taylor, Tim Whitlatch, Beni Zihlmann
Time-of-Flight Status
Sasha reports that they have hired a student, Chuck Brandon, to work
full time on measurements from the prototype. Again the immediate goals
are:
1. Repeat previous measurements with a constant fraction discriminator
2. Use scalers to measure efficiency
They are still gathering equipment for these tests.
Start Counter Status
All of the main ingredients for testing this summer have arrived at
FIU:
1. fine-mesh pmt
2. SiPM sample
3. scintillator in various sizes
4. full-scale light guide
Schedules
Mark pointed out the location of schedules for both the TOF and the SC
(they are linked from their respective detector wiki pages). These were
derived from the official project schedules and put into Fastrack by
Chuck Hutton. These are more templates at present; they are missing the
planning steps needed for the near to intermediate future, before real
procurement starts. We need to think about how to use this tool.
Action Items
1. Tim will find a copy of Chuck's drawing of the target area to show
us.
2. Elliott will ship a flash ADC to FSU for their test set-up.
3. FIU will study different geometries for the start counter.
4. Sasha will look at the bugs in his single-pi HDGeant study which
uses the time-of-flight.
