Minutes
Attending: meeting cancelled. Notes from Elton on ongoing activities:
- We have to a plan to use Vitali's setup to measure the relative time resolution for the production pream/sum circuit compared to the previous summed circuit attached directly to the SiPM. Fernando will modify the old preamp to have a socket. Carl will provide a new SiPM from the batch of first article samples.
- Beni has helped round up QDCs and a v430 crate, which can be used in the production setup.
- Monitoring features on the light guides have been defined and should be added to the final drawings
- Any updates on the bias/feedback studies?
