Fermilab is America's premier particle
physics laboratory. Collaborating with scientists from around the
world, we perform pioneering research, operate world-leading
particle accelerators and experiments, and develop technologies for
science in support of U.S. industry.
Mission
Fermilab is America's particle physics and accelerator laboratory.
Our vision is to solve the mysteries of matter, energy, space and time for the benefit of all. We strive to:
- lead the world in neutrino science with particle accelerators
- lead the nation in the development of particle colliders and their use for scientific discovery
- advance particle physics through measurements of the cosmos
Our mission is to drive discovery by:
- building and operating world-leading accelerator and detector facilities
- performing pioneering research with national and global partners
- developing new technologies for science that support U.S. industrial competitiveness

Super Conducting and Conventional Magnets Test & Mapping Facilities
Vertical Magnet Test Facility: Accommodate a device up to 3.85 m long, 0.61 m diameter, and 14,400 lbs. Configured for 5 psig sub-cooled liquid helium bath cooling with a minimum temperature 1.8 K. Multiple top plate configurations with vapor-cooled current leads. The power system is capable of delivering up to 30 kA, 30 Volts. Horizontal Test Stand 4: Accommodates cryostatted superconducting magnets, up to 12 m long, 0.85 m diameter in a 5 psig sub-cooled liquid helium bath with a minimum temperature 1.8 K and a maximum current 15 kA. Horizontal Test Stands 2 and 6: Accommodates cryostatted superconducting magnets up to 17 m long, 0.6 m diameter with 7 psig sub-cooled liquid and a forced flow up to 30 g/s. The maximum current available is 5 kA. Test Stand 3 Cryostat: Supports the testing of bare superconducting magnets and Resistive Temperature Devices calibration. The maximum size of the device under test may be 0.4m diameter, 0.8 m height, 800 lbs. weight. The system is configured for 4.5K saturated bath cooling with a maximum current available of 10 kA (however the installed current leads support only 0.5 KA at the moment). Cryogenic System: Helium refrigerator: 1,500 watts at 4.5K or 300 l/hour liquefaction capacity.
Superconducting Cavity Test Facility
Vertical Test Cryostats: VTS-1 cryostat supports a device under test up to 2.74 m long, 0.6 m diameter, and 1,400 lbs. weight. VTS-2 and VTS-3 cryostats support a device under test up to 3.6 m long, 0.86 m diameter, and 2,400 lbs. weight. The cryostats are configured to operate with a saturated helium bath cooling, 1.4 K minimum temperature and maximum steady power dissipation of 250 W at 2.0K. The VTS cryostats are magnetically shielded and include a radiation shield lid. They are equipped with RF power systems, DAQ Systems, Thermometry, and the Cryostat Control System. Presently the RF power system supports frequencies of 325 MHz, 650 MHz, and 1.3 GHz. Dressed Cavity Test Facility (MDB): Three test stands for fully dressed SRF cavities at temperatures down to 2 K with pulsed or CW RF. High gradient 1300 MHz cavities with pulsed RF, CW . 325 MHz spoke resonators with CW or pulsed RF. CW test of 650 MHz elliptical cavities (under construction). 4 Shielded reconfigurable enclosures. 3 Ganged cryogenic refrigerators each capable of 600 W at 4 K. Large vacuum pump provides in excess of 100 W at 2 K.

Superconducting RF Cavity Manufacturing, Inspection and Process R&D Facilities
Cavity Processing: Complete facilities for processing SRF cavities, both under tightly controlled R&D conditions and under mass production conditions, are available. Specifically, single and multi-cell cavities from ~100 MHz to 10 GHzcan undergo chemical polishing, electropolishing, and mechanical polishing.Cavity de-gassing ovens for 300 MHz cavities or higher frequency operate at up to 1000 °C under high vacuum. High-pressure rinsing with ultra-pure water and class 10 clean rooms for cavity assembly are also available. There is also an industrial laser system for local defect repair, and a replica system for diagnosis of cavity topographical features. Cavity Inspection: There are two automated optical inspection stands, used for inspection of 1.3GHz and 650MHz elliptical cavities, with the resolution of ~10 micrometers. This resolution allows for identification of defects from ~50 micrometers and higher. There is also a manual system, based on a telescope, with ~2 micrometer resolution. Argonne-Fermilab Cavity Processing Facility: Class 10 clean room for assembly; 2 EP/BCP tools for chemical surface processing of SRF cavities; 2 high pressure rinse systems; Ultra-clean water system; Trained Fermilab and ANL staff; Additional SRF cavity and cryomodule design, fabrication, and test capability is available at ANL.
