Private:Weekly Group 5/18/2011

This week we discussed the goals for the summer of each project. Please edit your section for more details.

Alex - Microscope Electronics
The logbook for this project is located here
 * 1) Understand present performance parameters, both of the model and prototype 1
 * 2) Where is the coupling/crosstalk?
 * 3) Is it capacitive/inductive?
 * 4) What is the proportionality constant between signal and crosstalk?
 * 5) Use
 * 6) Igor’s Matlab tool
 * 7) actual photo of board
 * 8) data fro JLab beamtest
 * 9) Goal date: July 1, 2011
 * 10) Interact with Jim about the board layout
 * 11) SiPMs need to be located at certain points due to the mechanical designs.
 * 12) This needs to be agreed upon before the making the layout and routing the board.
 * 13) Goal date: To be done at meetings
 * 14) Study the proposed layout from Fernando Barbosa
 * 15) Understand the key and modifiable components so that we know what parts can be adjusted when expanding to a full board.
 * 16) Goal date: receive layout by July 1, 2011.
 * 17) Make layout and produce prototype 2
 * 18) Have the boards sent out and come back
 * 19) Goal date: By the end of the summer.

Ann Marie - Active Collimator

 * 1) Extract gain, offset from A.C. data (10^9, 10^10,...)
 * 2) Find ideal mixing matrix that makes them independent
 * 3) Find algorithm to solve for x: {c1, c2, c3, c4} -> x estimator
 * 4) Apply algorithm to filtered time-series data
 * 5) Report on frequency vs. resolution with 60nA, 15nA

Documentation/paper at step 5.

Logbook:

Fridah - Diamond Profiling and Mounting

 * 1) Improve M.I. technique
 * 2) Take static images of mylar rings
 * 3) Build a translation stage for the mylar rings and take images for larger area
 * 4) Set up Computer DAQ for auto images and audio control over laser and speaker
 * 5) Take images of interference or phase

Jim
We discussed multiple designs for connecting the fibers to the boards.
