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.]]

Preparations for testing the tagger microscope in a live beam are underway. The ideal place to test the prototype is near another tagger magnet such as the one in Hall B. Thus the plan is to set the prototype downstream of Hall B's hodoscope.
