The only safety issue concerning the Bremsstrahlung radiator is that of induced radioactivity in the Cu targets and in the water used for cooling the targets. The water cooling system is a closed loop, using a portable welding-torch water cooler, located under the beam line just upstream of the target. The cooler is kept in a tray which is intended to provide secondary containment in case of a leak. The cooling system must not be breached or drained without concurrence from the RCG. Accidental breach or spill constitutes a radiation contamination hazard. A spill control kit, capable of containing a system leak or spill, is staged by the door to the hall. In the event of a spill notify the RCG.
