Blitzen is currently down and needs it’s optics cleaned. I don’t have time to at the moment but anyone who’s trained in it is welcome to do so. Some may need to be replaced, they’re bad.
There’s a note on the machine referring to a bad tube, which does not appear to be the case. We’ve had a rash of bad tubes recently, but we still need to do a power check by placing the power meter at the exit of the laser tube before declaring a bad tube. Replacing all the optics totals <$80, while a tube is ~$800. In this case, blitzen produced approximately 125W, which is well within spec.
