03.50 74-76Ni beam delivered to F11.
      F11 plastic rate ~1kHz.
      F5 C target in. F7 empty. F11 C target in.
      R7 started 03.51.
      Initial rate 0Hz in all DSSD.
      Removed all variable degraders and implant rate only up to ~1Hz in DSSD1.
      Will replace all variable degraders, enter B2F and remove fixed 5mm plate and work back from there.
      R7 stopped 04.00.

04.07 Beam returned to F11.
      F11 plastic rate 1.1kHz.
      R8 started normally.
      Will now gradually remove variable degraders.

04.18 Now removed all variable degraders.
      Implant rates from offline/full analysis below:
      *** DSSSD # 1 count:       697 old count:       354 dt:      1.03 s  HEC rate:    333.95 Hz
      *** DSSSD # 2 count:       592 old count:       308 dt:      1.03 s  HEC rate:    276.51 Hz
      *** DSSSD # 3 count:       696 old count:       349 dt:      1.03 s  HEC rate:    337.85 Hz
      *** DSSSD # 4 count:       688 old count:       348 dt:      1.03 s  HEC rate:    331.03 Hz
      *** DSSSD # 5 count:       609 old count:       312 dt:      1.03 s  HEC rate:    289.16 Hz
      *** DSSSD # 6 count:       229 old count:       116 dt:      1.03 s  HEC rate:    110.02 Hz

Leakage currents @ 04.21 attachments 1+2.

05.55 Takechi group want to remove C target.
      Moving variable degraders back into place.
      R8 stopped 05.59.
