CRMF Project Opportunity
Cryomodule Repair and Maintenance Facility Project
SLAC's research has driven significant scientific discoveries since 1962. The Cryomodule Repair and Maintenance Facility (CRMF) is essential for maintaining the superconducting cryomodules in the LCLS-II linear accelerator, ensuring they are tested and repaired for optimal performance. This capital improvement project will ensure these cryomodules are adequately maintained to sustain optimal accelerator operation and enable SLAC’s ongoing research mission. The primary objective of the CRMF Project is to establish a state-of-the-art facility for the repair, testing, and maintenance of cryomodules, thereby ensuring the continuous high-performance operation of the LCLS-II linear accelerator.
The CRMF Project will deliver a facility to keep superconducting cryomodules at the performance level required for SLAC's LCLS-II linear accelerator. Superconducting cryomodules are critical components of the LCLS-II linear accelerator, which delivers high-energy X-ray beams for cutting-edge scientific research.
Therefore, SLAC requires a dedicated facility to repair, test, and maintain cryomodules, ensuring minimal downtime and sustained accelerator performance. Without it, the accelerator's effectiveness and future research capabilities could be at risk.
The CRMF project will create a purpose-built infrastructure for the ongoing maintenance and testing of cryomodules, allowing SLAC to:
- Sustain high-performance accelerator operations by servicing 2 to 3 cryomodules per year.
- Improve in-house repair and testing capabilities with a cleanroom, shielded testing enclosure, and dedicated cryogenic systems.
- Support future advancements in accelerator technology by designing the facility for expansion up to 25,000 gross square feet (GSF).
The facility will be built to DOE High-Performance Sustainable Building (HPSB) standards, incorporating advanced cryogenic, electrical, and mechanical systems to support SLAC’s research mission for decades.
The CRMF project is fully funded by the federal government. The conventional building and site infrastructure construction has an estimated budget ranging from $30 million to $37 million. It utilizes a Design-Bid-Build procurement model to ensure competitive selection and adherence to DOE and SLAC infrastructure standards.

- Adherence to Instruction to Offerors and Evaluation Criteria

CRMF Contract Opportunities
The Cryomodule Repair & Maintenance Facility (CRMF) Project is advancing through SLAC’s infrastructure development plan to support the long-term reliability of superconducting cryomodules. The fully federally funded project follows a Design-Bid-Build procurement model to ensure cost efficiency and DOE and SLAC standards compliance.
SLAC is preparing for the procurement and construction phase, with DOE Critical Decision approvals guiding the project timeline. The facility will be constructed in alignment with high-performance sustainability and safety protocols, ensuring it meets current operational needs and future expansion plans.
The RFP is anticipated to be released in June 2025.
Project Requirements
The CRMF project includes:
- Construction of a new 21,000 GSF facility to house cryomodule repair, maintenance, and testing operations.
- Development of site infrastructure, including perimeter road access, stormwater management, and underground utility connections.
- Installation of critical structural and mechanical elements, including:
- A shielded cryomodule testing enclosure with 4-foot-thick poured-in-place concrete walls, a 3-foot-thick removable roof, and penetrations for a cryogenic feed line and waveguides.
- Two overhead bridge cranes, including a 20-ton crane in the main repair area and a 3-ton crane in the cryogenic equipment area.
- A cryogenic equipment room to support testing and maintenance operations.
- Designated outdoor concrete pads for cryogenic equipment, including helium storage tanks and cooling systems.
This construction phase will be carefully managed to minimize disruptions to ongoing SLAC operations, particularly in areas supporting LCLS-II research. The facility’s design allows future expansion (up to 25,000 GSF) to accommodate evolving accelerator technology and maintenance demands.
