So the suspect now is the fine focus coil in the column (one of the factory engineers predicted stitch shifts when a faulty fine focus coil is present which essentially replicated the errors we are now seeing) and the question now is how to get one of these sent to UCSB. They are a factory install item so for us to get one, and one that has been tested and confirmed to be fully operational, would require it to be taken from a tool currently under fabrication on the production line. |

=====Holography/PL: HeCd Laser Down Mon Dec 16th===== |
|||
The 325nm UV Laser will be unavailable from Mon. Dec 16th, through the christmas shutdown, and will be available again on Monday Jan 6th (or possibly earlier). |
|||
We will be installing the refurbished laser which will have higher output power. |
|||
We are close, very close, but still not quite there. And I am really sorry that is still the case… |
|||
Holography will be unavailable during this time, but all other PL lasers will be available. |

Chemical processing is UP
There was a short ~30min campus water outage, but it has now been restored. Chemical usage/processing is now allowed as normal. // Demis D. John 18:36, 16 June 2025 (UTC)
Raith EBL Update
Unfortunately the fix discussed in the last update turned out to be a good news/bad news thing. The good news is that the majority of the field distortion problem we have experienced since the install has been addressed. However the bad news is that there is still a residual settling effect that is distorting the field in one part of the field only and prevents the tool from fully meeting specifications. So it turned out to a layers of an onion kind of thing – because of course it did.
So the suspect now is the fine focus coil in the column (one of the factory engineers predicted stitch shifts when a faulty fine focus coil is present which essentially replicated the errors we are now seeing) and the question now is how to get one of these sent to UCSB. They are a factory install item so for us to get one, and one that has been tested and confirmed to be fully operational, would require it to be taken from a tool currently under fabrication on the production line.
We are close, very close, but still not quite there. And I am really sorry that is still the case… -Bill // Demis D. John 22:53, 13 June 2025 (UTC)

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)
