• Mamun made the first multi-alkali photocathode in the GTS!...just not on the puck!
  • There is about 1 micro-Amp of photocurrent when illuminated with the laser.
  • The photocathode shows photocurrent when ambient light enters the chamber through uncovered viewports, and when the RGA filament is turned on.
