|
TM3 and UCx#44 ran in ITE but issues with the cyclotron prevented proton beam delivery. Nonetheless, the target was heated and provided stable beam to
TITAN as well as for tuning and some tests.
Results of inspection of TM3 module after run: |

TM4 and TiC#7 target electrical check and HS leak check at SHC after target installation have been done. all results are good. I will attach the
checklist when printer is back to work.
TM4 HS line was helium pressure tested at TCS this morning. No leak. Also i leak checked TM4 top all air to vacuum seals at TCS. Everything |

New spring idlers were installed onto rotational chain drive for SHC roof. Operation ran smoothly in both directions to full limit. Chain was noted
to have adequate slack when not on driven side. Periodic checks to confirm operation will continue in the following months to guarantee proper operation. |

ABCD is short to 60KV bias. Othjer are ok. see attachment.
Found afterwards that this short was due to sparking through the multipin wire insulation where the wires pass behind the TBHT block "C".
See fault 17265. |

|
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 |

|
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 |

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
