===== 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 MA-6 will be unavailable Tuesday Feb 6th from 8 am to roughly 5 pm for its annual service visit. |
|||
The issue with the backside camera magnification getting stuck will be addressed during the visit. |
|||
I am pretty confident that we are going to have a fully functional EBL system available for use early next week! |

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. |

=====ICP #1 is down===== |
|||
| ⚫ | |||
The tool remains down. We did not find any "smoking gun" with the PC but did find that the PC's power supply had a non functional fan and the power supply did not test as good (granted it would still power up the PC). We will continue troubleshooting the PC issue in the morning. |
