Device and TEC Pressure Gauges

The contract pertains to the procurement of pressure gauges designed for use within the Material-Plasma Exposure eXperiment (MPEX) at Oak Ridge National Laboratory. These gauges must be capable of operating reliably in high magnetic fields up to 1 Tesla and temperatures reaching 150°C, while accurately monitoring vacuum pressures ranging from 10^-8 Torr to 760 Torr, as well as plasma pressures between 1 Pa and 10 Pa. The gauges are essential for maintaining precise environmental conditions within the vacuum chambers of the device, which is engineered to simulate the extreme conditions inside a fusion reactor and conduct accelerated lifetime testing of plasma-facing components, including those subjected to neutron damage. The solicitation was issued on April 25, 2025, with a response deadline of May 2, 2025. The contract is managed by ORNL under the NAICS code 3359, and the procurement is handled by ORNL UT-Battelle LLC, a DOE contractor based in Oak Ridge, Tennessee. Interested vendors can contact William Cramer or Morgan Records for further details. The project emphasizes sourcing either identical or domestically equivalent pressure gauges that meet the specified environmental and operational criteria to support the experimental objectives of the MPEX device.
