Light Guide Production
Two students are now working on polishing light guides. Along with improvements in the procedure the rate of progress has doubles recently.
PMT Testing
- All 194 PMTs have been received from Hamamatsu.
- 160 have been tested, with single photoelectron peaks observed from an LED source.
- 130 have been tested with the "americium source".
- About 100 of them have been tested with the "cesium iodide source". Two of the tubes show strange spectra.
- LED testing should be done in a couple of weeks.
- All testing should be complete in three to four weeks.
Scintillator Testing
Mini-TOF Construction
Module assembly should start today.
There was an issue bolting the mini-TOF structure to the floor, but that has been solved.
