JLAB Discriminators
First version was developed by James Proffitt and is used in tagger system. It was tested by Sergey Pozdnyakov. Results of tests are presented on the next few slides:
- Width distribution
- Threshold distribution
- Resolution of Leading Edge for JLab Discr.
- Resolution of Leading Edge for LeCroy 2313 Discr. (for compare)
- Resolution of Trailing Edge for JLab Discr.
Following changes were recommended to make that board suitable for CLAS12:
- remove preamplifier
- add test input
- add second output connector
As on October 11, 2007 the possibility of board redesign was discussed with Volker, Chris and Stan Majewski, and we are waiting for Stan's final word.
