The ALS Brain Drain

Another long night at the ALS. Right now the x-ray beam is off for some reason. It shut off unexpectedly at 11:30. I've been sitting here waiting for them to start it up again, but it looks like the control room is waiting until 1AM (the regular refill time). I am dead tired from these long nights, and I didn't get much sleep during the day. I think I'll go take a walk around the synchrotron ring and try to wake up a bit.
