We describe the Image Acquisition system for the Injection Dump. This system visualizes the different beamlets, on the vacuum window after the H beam is stripped of its electrons by two stripper foils. One beamlet is from H with its electrons stripped by the first foil and the second beamlet has it final electron stripped by the second foil. We used the PXI platform to implement the data-acquisition including timing decoder. We describe the hardware and software for the system. We use a standard non-radhard GigE camera to acquire the image from the luminescent coating on the dump vacuum window. To lower the radiation damage to the camera, we shield it with stainless steel blocks. We present radiation measurements before and after shielding. We also show the radiation damage over time to estimate the camera’s lifetime.
