10/11 at 18:00 Magnets are turned on with 3.0GeV/c.
10/12 at 11:00HER started injection of beam.

Result of last week and planHER 700mA, LER 1200mAWe observed beam ～ 30Hz.Beam energy looks constant.(according to oscilloscope)When shutter is closed, rate of the beam goes down 0Hz.
Plans of this week•Measurement of correlation between beam intensity and - HER current - condition of the vacuum correlation of intensity between upper side of shutter and lower side • Measurement of beam profile with electron monitor.• Adjustment of magnets adjust currents of B2-4 between -1% and +1%
