    keyword=Power Interruption

    At approximately 4:30am this morning, there was a brief power interruption, which tripped pretty much everything.

    The accelerator went down, as did the CHL.

    The magnets tripped, and the momentum values were set to 0 until the helium levels can be restored.

    The LH2 and LD2 targets started warming up, reaching a maximum of 35K for the LH2 loop and approximately 30K for the LD2 loop. The target fans and the ladder are not responding and it appears they have suffered a power failure that may require a hard reset.

    Communication with the detectors through the Hall A Tools appears to be down.
