Final acceptance tests of the Mirror Fusion Test Facility (MFTF-B) were completed in February 1986. These tests verified performance of the following subsystems: the magnet system, the vacuum system and vessel, cryogenic systems, 80-keV neutral-beam sources and power supplies, microwave power systems for plasma heating, the supervisory control and diagnostic system, and the local control and instrumentation system. The entire magnet system was operated at full field continuously for 24 hours. The largest field alignment error under full load, determined using an electron beam technique, was 6 mm, well within the required precision of 15 mm. Absolute values of the magnetic field were determined using nuclear magnetic resonance techniques and were found to be within 2% of predicted values. All magnetic protection systems and fault protection systems were tested at full load. At 4.35 K, the cooling capacity of the liquid helium system exceeded the 11 kW rating and the nitrogen reliquifier met its 500 kW rating.
