TJNAF is procuring a dilution refrigerator (DF) system equipped with a superconducting solenoid to support the Fusion Project experimental program. The DF shall reach sub-10 mK temperatures while providing high cooling power at 100 mK and must be integrated with a superconducting magnet capable of producing fields of at least 8 Tesla.
