5/19/2003Manuel I. Martin Immediate Goals GOALS Intermediate Goals Long Range Goals “Get two layers of the ‘tower’ working as soon as possible with minimum expenses” “Get at least one layer of the ‘tower’ working as soon as possible using the Hamamatsu APD with minimum expenses” “Design ‘full’ DAQ system for the ~40K channels prototype for test on ‘a’ beam line”

5/19/2003Manuel I. Martin People / Assigments Until classes start at UIC  Ian Harnarine  Work on the QPA02 APD (Hamamatsu)  Help on procurement  Shahab Khan  Work on the XYZ controls and Data Acquisition

5/19/2003Manuel I. Martin Make decisions to achieve immediate and intermediate goals as follows:  Design two separated ‘light tight’ boxes  to accommodate 6 PMT (16 channels)  to accommodate 2 Hamamatsu APD and/or one RMD SiAPD  Transfer the setup that Kurt uses to instrument 2 layers of the ‘tower’ Start collecting necessary data from  Hamamatsu   RMD ????  QPA02 (R. Yarema ?) Design  holder for the Hamamatsu APD (conceptual, interface with Sasha)  PC Board to interface Hamamatsu to QPA02 (impossible until data for QPA02)  Holder for the RMD SiAPD (impossible until data for QPA02)  PC Board to interface RMD SiAPD QPA02 (impossible until data for QPA02) Progress to date:
