keyword=Beam Tuning Continues
By 04:15 the beam size from harps had been checked and looked fine:
1H03A: 230 x 202 um2
1H03B: 220 x 177 um2
We then checked the raster and adjusted the size from 11 x 8.5 to 11 x 7.5,
since the y raster size at target was closer to 6 mm.
We then
moved to the LH2 target to begin production. But then the ep ion chamber
began to trip and MCC began to tune again.
The target was moved to optics, since the beam position was changing by a
considerable amount.
