Evaluation of cooling channel configurations for actively cooled limiters
The Sandia electron beam test system (EBTS) was used to heat one side of 7.7 mm and 12.7 mm inside diameter copper tubes. A single tube placed horizontally in the EBTS vacuum chamber was heated on the top by a rastered 30 kV electron beam. The test section was cooled with water supplied by a centrifugal pumped closed loop system. Coolant inlet and exit pressures, flow rate, inlet temperature and temperature rise were measured as were the target's surface and backside temperatures. Water calorimetry was used to determine the actual delivered power, with all system operation and data collection under computer control. The flow within the heated region was studied by viewing directly through the tube.
