Super Gas Cherenkov Detector
(GCD-3)
The "Super" GCD, also known as GCD-3, is a high-sensitivity gas Cherenkov detector designed to take measurements of low energy gamma-rays as little as 1.8 MeV. The detector has previously been used in collaborative research with MIT on a National Laser Users Facility experiment.

Work is done on the GCD-3. (www.lle.rochester.edu)
