    keyword=ESR Crash & the Single Septum

    at about 1719, the septum tripped off. we had been running at 250A for Target Field Mapping. the trip was caused by low LHe levels. the magnet started to warm up b/c it was recieveing no LHe. it's just starting to level out at about 9.5K (magnet coil). the yoke maxed at 5.3K. the LHe has been replenished. both the dump switch and power supply are off.

    cause of crash was a fan trip in the ESR cooling tower.
