abstract = {The Proton Power Upgrade (PPU) increases the the Spallation Neutron Source (SNS) accelerator power from 1.4 MW to 2.8 MW and calls for a modification of the Ring Injection Dump beam line. The charge exchange injection technique to accumulate proton beam in the SNS ring results in multiple beam spots on the ring injection dump window. To properly setup the new injection beam line, the size and locations of the beam spots must be measured. We plan to use a camera to look at a fluorescent coating made of Chromium Oxide doped Aluminum Oxide. To simplify the optical path, we want to place the camera in the tunnel. While radhard cameras are available, they typically are more expensive and have worse performance. To study the feasibility of non-radhard cameras, we measured the radiation in the tunnel in unshielded and shielded locations. We compare the radiation measurements with results from a CERN HiRadMat study and tested the cameras during full power beam to show that the non-radhard camera is an option for the Ring Injection Dump Imaging System.},
