The CAlifornium Rare Isotope Breeder Upgrade (CARIBU) for the ATLAS linear accelerator requires the transport of very low intensity ion beams through the accelerator. Weak beam diagnostic stations at several strategic locations throughout the accelerator will be installed to duplicate beam position as measured with a guide beam. An ANL designed Beam Profile Monitoring Device will use secondary electrons into a multichannel plate MCP, onto a phosphor screen, and then into a CCD image. A video capture program to enable averaging and integration of weaker beam signals from the video devices is being developed using ITT Visual Information Systems IDL software on a Linux based PC. The software will process the image from the CCD camera and average the frames together to produce a viewable image of the beam spot. This will allow the operator to adjust the beam and potentially match the live image and averaged images to previously saved images. The software will also allow the selection of a particular diagnostic location to view and control from a single interface.
