1. CDC

CMU group is studying sources of noise in the preamp electronics. So far they are making progress on understanding the sources. Jlab is shipping updated cards to CMU within a week for them to test.
CMU has shipped an example of the coupling from the chamber to the electronics outside the gas volume to Jlab. Jlab is still trying to figure out how they are supposed to work.
CMU group is working on the time-distance conversion function and implementing it in software.

2. BCAL

Blake is finishing up the test beam analysis.
They are testing adjustments of the lead-fiber ratio in MC
They are studying the effects of a pre-radiator in MC.
Andrei has identified the best SiPM array he is getting set up to couple it to the test module and use it to look at cosmic rays.

3. SiPM work by Jlab detector group

Carl attended IEEE meeting last week and presented his work on silicon photomultiplier tests.
Technology seems to be advancing at a good pace.
Sensl seems to be leading the effort for large-area devices.
Hamamatsu now has produced a 3mm x 3mm device.
