===== Raith EBL Update ===== |

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. |

The service engineer had to order some more parts for the SEM. He’ll be back tomorrow to continue troubleshooting the skewing issue. In the meantime, the tool is useable and is only showing the skewing issue within the mags of 5.5k to 8.5k. Please let me know if you encounter any other issues. Thanks, Aidan |

I am pretty confident that we are going to have a fully functional EBL system available for use early next week! |

We will be taking down the DSE to changeout the turbo pump next Wednesday (5/28). If all goes well the tool should only be down for the day. I’ll keep you updated with emails. |

Raith EBL Update
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.
I am pretty confident that we are going to have a fully functional EBL system available for use early next week!

SignupMonkey + Wiki: Off-Campus Access
Due to a DDoS attack affecting the Signupmonkey server, we have restricted access to the website to US locations only, including both the Nanofab Wiki and Signupmonkey.
If you are off-campus and experiencing issues, please utilize the UCSB VPN to access our sites. Here are the installation instructions for VPN on your device. You will need your UCSB NetID for download and installation - you would have received a UCSB NetID when you started using the NanoFab:

New Gowns: Toolbelts purchases
We are required to switch to new gowns in January. The new gowns won’t have pockets, but you are allowed to purchase cleanroom tool belts. Please ask staff for which tool belts you can purchase.
Two vendors for cleanroom belts we are using are listed here, you may request others:
- Uniform Technology Tool Belt - note the waist size, the 49” belt fits up to ~36-38” waist.
- HiTEC Fannypack

Suss SB6-8E
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)
