===== 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. |

=====MA6 is up===== |

JEOL Service will be here tomorrow morning to look at the situation. They had me try a couple of things today that didn't work. It is pointing to a gun replacement at this point. They do a have a spare gun at the JEOL facility in Pittsburgh ready to go if needed. |
|||
We are close, very close, but still not quite there. And I am really sorry that is still the case… |

The MLA will be receiving its biannual service the week of June 24. The work will be performed from Monday 6/24 through Thursday 6/27. They plan to have the work completed in 3 days but want to have the 4th day available if needed. The tool will very likely be unavailable overnight Monday but should be available the rest of the |

evenings. |

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)
