On the 12th, the whole day was devoted to the maintenance and calibration.
Later in the evening, when we put the whole detector on for data taking,
a problem was noticed on the power supply for the PHRASE on the super module
6. It was phasing in and out. uVax 3 was taken out of the acquisition.
On the next day, the power supply was replaced and found to be stable.

On the 14th, the run crashed in the morning and the scintillator H.V. power
supply for super module 4 was found to be off. The supply was put back on
and the run was started. Soon after, the scintillator H.V. power supply for
the super module 5 went off and it was restored.
Currently, the full detector is on and taking data.

2. Calibration and Maintenance
----------------------------

LED calibration was performed on uVax 3, LED TDC calibration on uVaxs 2,3,
and Slow Monopole calibration on uVax 3.
Before the calibration, all the modules in the switch boxs are inspected
and number of problems are identified and fixed. This time around, the
calibration can be done on all the counters except about 0.4% of them.

I would like to thank Stephane, Ioannis, Erik, Stefano and Paolo for their
enthusiasms in teaching me all the things for becoming a MACRO shift
worker. A special thanks is given to Ioannis for helping us (Brajesh, Yinzhi
and me) find our way in the strange but wonderful land, ITALY.
