Light Flasher
The following graphs are taken from the sum ADCs values of the LED flasher for July and August 1999, using the Light flasher set to 40 ns pulses and recorded by the camera of the Cangaroo II telescope. The July graphs were taken using aperture stops to control the brightness of the flasher. There is also a 20 ns point for comparison. The August graphs were taken using neutral density filters with either 100% or 30% apertures. The measurements also show an 8% decrease in ADC counts from July to August. This may be due to PMT changes.
July 1999
