E-Counters output signals during beam on conditions of

June 29th to June 30th 1997

The following documents in postcript format describe the output signals from a random set of E-counters as measured in the Hall-B counting room during the night of June 29th to June 30, 1997.

The pulses correspond to electron traversing the E-counters scintillators. The measurements were performed for various applied high voltages ranging from 1800V to 2200V. It is important to remember that these measurements were performed in the counting room so that the attenuation of the signals from the experimental area to the counting room is a factor of 2. In other words, the magnitude of the signals in the experimental hall is twice that shown in the plots.
