Day 43

Morning
It was time for EBW 4 to get a beam going. The day started with Tony and Jim troubleshooting a few problems while trying to get the bombardment and filament current working. I followed them out to watch the beam get going. There was a succession of problems all day though. At around 10:30, they pulled the gun and took it over to Curtis for a rebuild. Got that pumping and took a quick lunch.

Afternoon
More testing. The SCR's still weren't firing right. Tony put in a few resistors to check out how the board was doing independent of the gun. Turns out it is not the gun. He got a space heater to use as a load to test the thing out. I spent time in the operator shack turning the bombardment on and turning it up. That won't be necessary once the heater gets used to troubleshoot.
