FEE64 temperatures OK - attachment 10
 
      ADC data item stats - attachment 11
       increased rates observed esp. DSSSD#2 n+n

Merger etc - attachment 12
      rate increased x2 cf. overnight

WR timestamp - attachment 13
       aida03 out sequence

09.25 MBS data relay restarted

Merger data links - attachment 14
       aida03 rate zero

per FEE64 1.8.W spectra - 20us FSR - attachments 15-16

per FEE64 Rate spectra - attachment 17
      increased rate for DSSSD#2 n+n FEE64s in particular

MIDASsort online analysis - attachments 18-19
      per DSSSD e_front versus e_back for LEC (20keV/channel) and HEC (20MeV/channel)
      observe light ions (LEC) c. 2MeV
      observe low rate of high energy ions (HEC) c. 600MeV
      similar energies in both DSSSDs for LEC and HEC implying both types of event have range >> 2mm Si

20.30 Primary c, few kHz 170Er beam to S4 - upstream s/steel flange removed
      Start of stopping range calibration in the implantation stack - currently ion appear to be stopping in DSSSD#1 (upstream)

Decay and implant events as function of time showing spill structure - attachment 32

per DSSSD e_front versus e_back (HEC, 20MeV/channel) - attachment 33

per DSSSD x versus y hit pattern (HEC) - attachment 34
       mapping to be configured but clear ions are mostly implanted in centre of DSSSD#1

2D colour/contour levels - attachment 35
