This is the page for the EPD meetings. I suppose we could add a subpage for each individual meeting, that way only files relevant to that meeting would appear there.

Isaac, work faster!

EPD meeting April 13, 2016

Agenda copied from Alex's email:

Hi All,
 
We have a brief EPD meeting today to discuss:
 
- EPD review: To do (so far)
 
- Fiber to SiPM coupling (status)
 
- aob
 
Best,
 
Alex

Attached is Isaac's talk on the SiPM board design.
