Analysis of the CCD camera
There are only a few methods in determining the current of the incoming beam throughout a run. The primary method being used involves analyzing the data received from the elastic monitors and observing how the counts fluctuate with time. As the elastic monitors have been known to be unreliable, alternative methods of determining beam current are needed. A CCD camera has recently been installed in DRAGON, which looks upstream towards the gas target. The reaction between the incoming beam and the gas target creates a small light output, which the camera is able to capture. The main function of the camera has been to help ensure that the beam is centered through the target, but as the camera also produces data that represents light intensity, it can be used to track the current of the incoming beam.
