Detectors
- The detectors are described in the following POLOG Entry:
http://opweb.acc.jlab.org/CSUEApps/elog02/elog_item.php?elog_id=1542515
https://cebaf.jlab.org/elog/entry/1542515
Data Sheets
- The Acrylic Light Guide is 0.125 inch x 1 inch wide x 2 inch long (data sheet: media:Light_Guide.pdf).
- The Plastic Scintillator for the DE detector is an EJ-212 machine finish of the size 1 mm x 1 inch x 1 inch (data sheet: media:EJ-212.pdf).
- The Plastic Scintillator Rod for the E detector is an EJ-200 (data sheet: media:EJ-200.pdf) of the size 3 inch diameter x 2.5 inch long painted with EJ-510 (data sheet: media:EJ-510.pdf) with one end clear.
- The 1-inch PMT is R6427 (media:PMT_R6427.pdf) in an H7415 Assembly.
- The 3-inch PMT is R6091 (media:PMT_R6091.pdf) in an H6559 Assembly.
