    keyword=Comparison of 500 and 750 Tach signal/background

    A quick look at the PID and coincidence to accidentals rates from the waterfall data taken last night. The 500-Tach data was scaled up by 2.4 to 'match' (by eye) the pi, K, and proton peaks.

    The accidental background is roughly 10% higher with the 750 Tach speed when compared to the 500-Tach data.
