PrimEx Event Viewer (pev)

In addition to the statistical monitors described in the previous section, a graphical single event viewer has been written. The PrimEx Event Viewer or pev was written to provide a way of quickly looking at individual events in detail. It has views of the HYCAL, tagger, and Pair Spectrometer. Figure 3 shows a screen shot of an early version of the viewer looking at Monte Carlo data. The event viewer will read events from the ET system on clon04 in the counting house and will be in continuous operation during data taking.
