Raith replaced every item that was left to replace in the column on Monday. Yesterday they performed some quick tests @ 50kV and the issue with deflector settling was gone. This is an extremely positive result! It almost certainly suggests that the issue has been repaired. However, tests @ 100 kV remain to confirm the behavior and we are doing so later today and early tomorrow morning. |

We finally got the slit valve assemble to seal correctly after making a number of mechanical adjustments. The tool is currently running an O2 clean and should be available to use within the next 10-15 minutes. Please let us know if you encounter any issues. The load lock seems like it's taking a while to get down to 0mT but that could just be a product of being open for the past several days. |

Thanks, |

We found a blown resistor (and a questionable op amp) on one of the boards that contains the z-axis motor circuit. However, we still cannot get the tool to initialize. Next we will try swapping out the hard drive again and run some more tests.
I will send out an update once we have one. -Aidan // Demis D. John 00:35, 8 December 2024 (UTC)
ICP1 Down
The board we were waiting on arrived, but it did not resolve the tool issue. We are working with Panasonic on the next steps. //Vraj Mehalana 14:17, 1 March 2024 (PST)
