PMT Test FacilityPMT Test Facility

• Facility designed to study the response of PMTs for light levels of a few pe’s to millions of pe’s. Mantained by Hogan Nguyen.

• It consists of a liquid dye contained in a quartz vessel, pumped into flourescence by a nitrogen laser.   The flourescence  light is  viewed by 2 Pin Photodiodes and a quartz optical fiber carrying light to a dark box containing a PMT.   The laser light intensity arriving at the dye can be adjusted by a variable filter wheel.

• The 2 Pin diodes are digitized by a 20-bit Burr-Brown ADC  (0.5 fc/count sensitivity).   The linearity of the Pin Diode Burr-Brown ADC combination is better than 0.5%  over the entire dynamic range.
