N2 - The R & D Energy Recover LINAC (ERL) at Brookhaven National Laboratory is undergoing continued development in parallel with piece-wise commissioning efforts as installation of each subsystem is completed. While the machine is planned to operate at low intensity with short, low frequency pulses during the commissioning phases, on going design efforts continue to provide a solution to measure the beam distribution inside the high power electron beam dump using several parallel methods. For low power measurements, this includes a new rad-hard version of long 7/8 in. Heliax ion chambers [1,2] that encage the dump both in circular and axial directions. For high power measurements, this includes both "pinhole" like multipoint imaging of the dump with ion chamber beam loss monitors [3] positioned over an array of holes drilled in the shielding around the beam dump as well as an infrared imaging system to peer through an upstream dipole chamber in the extraction line to monitor the temperature distribution on the target surface inside the dump. This paper presents the design details of these three systems that work to ensure the proper distribution of the high power electron beam on the target in an effort to avoid reaching the thermal limit of the water cooled beam dump [4].
