    keyword=100x to 1000x the radiation dose during early 5 pass

    100x to 1000x the radiation dose during 5 pass steering then we had during 2 pass. Also note the early 5 pass doses are with _tune beam_ vs. the 2--5 uA CW beam 20 hours earlier (at 2 pass). That didn't seem right so I gave the crew chief a call to let him know. He wasn't too concerned about it so perhaps it's normal.

    First figure shows various radiation monitors over the last 36 hours (2 pass beam dose in first half), 5 pass tune beam in the last couple of hours.

    Second figure shows the last 8 hours. The huge spikes between -4 hours and -1 hour are with _tune beam_. (Is that still normal?)
