Description

The Lujan Center at the Los Alamos Neutron Science Center utilizes multiple tungsten spallation targets to generate intense bursts of pulsed neutrons for academic, national security, and industrial research. These targets are cooled by a closed loop, deionized water system. As part of the safety basis of the facility, safety rated flow switches are implemented to ensure sufficient cooling is delivered to the targets. An upgraded target system was installed in 2022 that contains a new third tungsten target. This new target system required a redesign of the water cooling system. As part of this rebuild, new custom flow switches were developed, tested, and installed to replace the previous style that suffered multiple failures over the previous years. The new flow switches are adjustable to meet different flow rate requirements and do not contain tight tolerances that caused the previous flow switches to fail.
