Tagger microscope prototype construction

The design of the Tagger Microscope prototype is currently underway. Below are topics concerning the branches of the work required for its completion and testing in preparation for the construction of the fully instrumented Tagger for Hall D in Jefferson Lab.

Project Branches

R&D into Fiber-Array Fabrication Techniques

The design concept for the Tagger Microscope calls for a scintillating fiber detector array along the focal plane of the spectrally-analyzed beam of electrons. This is a two-dimensional array of broken up into 2 mm² patches (as shown in the adjacent figure) representing the cross-sections of the square scintillating fibers. To avoid placing photo-sensors along the path of the electronics, the scintillation light will be delivered to separately-mounted sensors and electronics via clear fiber waveguides.

Development of fiber cutting, polishing and gluing techniques to enable the most efficient capture and delivery of scintillation light is being conducted by Carl Nettleton
