0010: Compton rate at 30kHz/uA, Asked MCC to tune 
0013: p0_L to 0.69934GeV/c, Target to He (beam compensation on)
0055: MCC reports beam down due to loss of cyogenics.	        
0100: Switching p0_R to 0.652043 GeV/c, going to C12 target

Lost CHL and ESR, accelerator down, all magnets tripped
Target loops vented
Set controlled access. Survey complete

0330: Cryo reports that we can start recovery
0550: Spectrometer magnets reset
      p0_L = 0.69934 GeV/c
      p0_R = 0.65204 GeV/c

0615: JP out of hall, Hall A ready for beam
      Putting in empty target to allow MCC to bring tune beam

0625: Request harp scans on A and B
      A: 244x276 um
      B: 134x236 um

0635: Checked raster: (Run 4464_Left) Looks OK
      Inserting C-12 target
      Resuming production @ 50 uA
      OTR looks OK
      Compton rate a little high (~25kHz/uA)
      Giving MCC some time to tune

0705: p0_L to 0.65204 GeV/c, target to He (beam compensation on)
      Compton rate much improved (1.5kHz/uA @ 50uA)
