Prototype
The sample counter has still not come in from McNeal. It has been built and now is "in finishing."
Read-Out
Mark reported on his conversation with Fernando. Fernando has started thinking about the design of the SiPM board • 3 sectors ok • 3 bias voltages • outrigger board • thermister, not used ∘ elton and werner prefer it ∘ does set point temp need to be known in advance?
new geometry for stat counters ready • remove long light guides • puneet will do it • may have to add some material for sipm boards
LED system • usefull to vary intesnsity, check efficiency, if fsast, can look at timing resolution
Mechanical
• inner support to be machined out of one piece • no foam on the outside • light-tighting an issue
