Temperature setpoint = 113 K

Target density is OK for now. S1 vaies between 2E-8 and 3.5E-8 mbar. E4 between 1E-9 and 1E-8 mbar.

Detector motors functioning well. Moving between 23.1 mm and 67.43mm. Move in and move out counters the same. Correlation scalar 8 for detectors moving is seen on aida1

Rutherford rate peak varies between 10^3 peak height when fully in and ~10^2 when fully out. No peak from halo seen in rate.

Beam intensity ~ 1E8

Merger OK

Data rate ~ 1700 kb/sec

Run is Run 87 - started 10:34

Data spy restarted at 15:00 so only include Run87 data.

Leakage current = 3.205 uA

Fee Temperatures OK

System checks OK - wr fails

White Rabbit error counter test result: Passed 0, Failed 5

Understand the status reports as follows:- 
Status bit 3 : White Rabbit decoder detected an error in the received data 
Status bit 2 : Firmware registered WR error, no reload of Timestamp 
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR
