Raffles Institution, Singapore AbstractA black and white CCD camera can be used to detect x-rays. Cameras with digital readout have been used as single hit spectrometers and analog cameras have been used as imaging detectors by many groups. We have developed a simple camera which is able to record both spectral information and spatial distributions simultaneously for repetitive events. The camera system uses pulse height analysis of single x-ray photons interacting with the silicon to get spectral information. Due to the small number of events available to the camera (limited due to number of pixels) spatial information becomes meaningful only by overlapping several images. This camera was used on the NX2 plasma focus device to investigate the hard x-ray production from the anode tip. An anode with an initial 5 mm diameter hole was used. A CCD based pinhole camera was set up to view the anode at 0, 42 and 48 degrees from the normal. Results show that the x-ray emission is concentrated near the center of the electrode consistent with the interpretation that the hard x-rays are produced by electron bombardment. Spatial resolution is high enough to observe the hole in the electrode. Repository Staff Only: item control page
