In the previous run while working on the target it was discovered that the valve was closed! Probaly this happened around 10 am, we are not sure.

The gas target inlet valve is open again, working on the target.

Beam energy = 3 MeV

Horizontal beam position = 7.0 mm, vertical beam position = 0.0 mm.

Beam intensity at inj ~ 2.5e7

Detectors are positioned IN pneumatic only. Left arm = 62.71, right arm =  64.60 mm

Histograms and stats zero'd, monitoring code restarted.

Beam in the ring ~ 7 minutes.

Pressure in YR09 E target ~ 4.5e-11 mbar.

Still no target!

Merger OK, Tape server OK

ADC data item statistics looks as before. OK

FEE temperatures look OK

System checks OK

We have the target back. S1( grafana) 4.8e-8. The target thickness read by the system 5E11 atoms/cm2 but apparently the formula is wrong and the value should be almost e12 atoms/cm2.

. We have now proper beam and target and we
