Since only energy tagging is required, the members of the 5-channel columns are summed to produce one signal corresponding to that energy channel. The exceptional columns are marked in red - the signals from their individual fibers will be read out to ascertain focal plane orientation and vertical spread. Note the segmentation of the 100-energy bin (column) array into 20 fiber modules. This is thought to be a more manageable design, corresponding nicely to the photo-sensor/electronics grouping.]]

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.
