Review of minutes from the last meeting

We looked over the minutes from the July 21 meeting.

  • The light guide sent to Polymer Plastics for vapor polishing came back. Sasha reported that Paul was not happy with the surface quality.
  • Chuck received the dimensions of the steel tube from Paul.

Prototype status

Sasha made some further tests to investigate the effect of trigger thresholds on his ADC spectra and to obtain time walk corrections. See his web page for details. He is able to extract corrections and improve the resolution in mean time only from 265 to 250 ps by applying them.

Sasha could use some more splitters. Mark will ask Fernando about making some more.


Mark has started work on a draft of the statement of work. The text is written. It is missing some milestones. He will get those from Elton's schedule.
