Detection system for forward emitted photons at the Experimental Storage Ring at GSI
V. Hannen, D. Anielski, C. Geppert +10
A single photon counting system has been developed for efficient detection of forward emitted fluorescence photons at the Experimental Storage Ring (ESR) at GSI. The system employs…
