Our Goal is to mount the FPD. That is the 16 pairs of scintillators on each octant (left pic.) .  Each individual detector is made out a scintillator glued to one light-guide at each end (right pic.). Each light-guide are optically coupled to a PMT.

Each scintillator/light-guide assembly is equipped with a Gain Monitoring System (GMS).   In the Cleanroom (EEL Building at Jlab), we are mounting 4 of the 8 G0 octants. They  ultimately  have been moved to Hall C (JLab) and  slided in the detector support : the Ferris Wheel (right pic.)
