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.
