An update from FNAL on last Saturday's "incident" at FNAL.  The new mode of operation has not had a significant impact on our test beam operations other then the lost time on Saturday. Kudo's to the FNAL Accelerator Division for a fast recovery.

The Main Injector accelerator at Fermilab is operating again after a transformer located at MI-60 malfunctioned and resulted in a fire (see email sent to Fermilab users on Saturday, April 23). Because the Recycler ring is still off-line, the Main Injector is delivering neutrino beam intensities that are about 50 percent lower than usual (about 300 kilowatts instead of 600 kilowatts).

We are exploring a temporary fix that would allow us to return the Recycler to operation by connecting RF systems for the

Recycler to a Main Injector RF supply. Replacing the transformer and repairing the power supply damaged by the fire may not be possible before the 2-month maintenance shutdown of the Fermilab accelerator complex scheduled for this summer.

For more information about the transformer fire, see this article on the Fermilab at Work website:
