Nb#10 never worked online - repeller had no effect on the beam and one of the RF wires was touching HVC. Max 60pA was seen on the source cup. See notes

TiC#7 failed after two weeks of operations - measurements in the electrical room indicated that the negative side of the CHT was broken (35kOhms to the
rest of the target). This was likely due to a large number of proton trips during this target run. At every trip I could see the CHT voltage getting higher
and more unstable. This cahnge in voltage was reflected in the unstable anode current and fluctuating RIB beam intensity, as a direct result of the fluctuating |

|
With the new TiC#8 target installed on TM3, there was a ~7kOhm connection between TGHT/TBHT (A/B/C/D) and HV common. The standard electrical check on
the module showed standard values, so it was assumed the problem was inside the target.
Started removing bolts/water connections one by one to see if any of them had an effect on the measurement. Found that disconnecting the multipin |
