Some problems with the DAQ. Symptom is that most of the scalers are not counting. Doug stayed late to help. Called Karen who helped us track it down to a flaky state of the MLU in the CAMAC trigger crate. She talked talked us through reloading trigger and systems are up again ~4:45 AM.

The red needle hovers around 250 C on tape/hour

Junk runs 10696-10698
