Observed short burst of low energy noise on aida1, lasted <30s (attachment 8).

Temperature setpoint = 113 K

Target density OK S1 vaies between 2E-8 and 3E-8 mbar, E4 between 1E-9 and 1E-8 mbar.

Detector moving well between 23.1 mm and 67.43mm, move in and move out counters the same. Correlation scalar on aida1.

Rutherford peak varies between 10^3 and 10^2 depending on detector position, noise peak varies with detector position -> lower further in.

Beam intensity ~1E8

Merger OK

Data rate ~ 1900 Kb/sec

Leakage current = 3.208 uA

Temperatures OK

System checks - 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

Avg ring pressure = 5.5 E-10 mbar. Ring pressure tends to oosciilate between ~4 and 5.5 E-10 mbar
