Energy change to 1.254 GeV:
-------------------
8:20... Start energy change. MCC said that it will take about 2 hours.
Kin#90
-----
9:15...Change the Hadron Momentum to 1.4730 GeV/c.
..........Cycling Hadron Magnet: Q2 and Q3 setting to 1400 Amps.
..........Change Electron Momentum to 1.2347 GeV/c.
..........Cycling Electron Magnet: Q2 and Q3 setting to 1600 Amps.
9:30...Move Electron Spectrometer to 15.2 deg. (it takes 20 min).
10:30 MCC called and said that we can't run with OTR in for currents higher than
50 microA during the night because the accelerator trips too much radiation.
10:45..Asking for 4 microA, raster off to do the HARP measurement.
11:00..HARP Scan, I = 4 microA. Run#588. Raster off.
11:10..Raster size checked with carbon target.
11:20..HARP scan, I = 4 mocroA. Run#589. Raster on with carbon target size not ...........good.
11:50..HARP scan again (raster size not good), Run#590.
12:00..HARP scan again. Run#591, 592, 593..(raster size not good).
12:05.. goes to the next shift.
