More polarized D2 data.

dblast13, the computer with the online gui is frozen, the online gui was started on dblast09. Hopefully someone can look at this in the morning.

At 6.30pm there was a series of fills where the current would suddenly drop by half close to the start of the fill. CCR tried to find the cause of the problem, however, it went back to normal by itself.

There was a small water leaak in transmitter 3, however, they continued to deliver beam and fill the ring until someone arrived to fix the leak. Beam was done for over an hour. Immediately after beam was turned off, the ABS TCell alarm went off. The RC was called and we thought this alarm was because the beam was no longer warming the target cell and so it got colder than the low alarm level. Everything was fine after beam came back and the cell did no get colder than 89K.
