    keyword=Shift summary

    16:00 start of shift, no beam. still in tunning.
    20:33 We contacted MCC and they said that beam tunning will not improve until tomorrow.
    20:43 asked MCC to do a HARP scan results: H160um V140um
    22:30 MCC got a HARP scan results of H121um V117um.
    Checked T3 rates with 5uA:~300Hz both raster on and off.
    Checked Spot size - 4X6
    22:51 we start taking data, even thogh current has not been steady for the last 15 minuets.
    23:01 Changing target to Pb
    23:22 on spot we saw that we hit the frame on the y direction.
    trying to move the beam to (

    23:46 we'll continue production with beam center on (-4,2)

    Starting raster size check, 5uA on C target.





    1284 - 1286 Junk
    1287 - ~40uA on C target, current is not steady. raster on.
    1288 - 37uA on Pb target. raster on.
    1289 - 1294 spot runs
    1295 - 37uA on Pb target. raster on.
