 +Removed the beam-blanker again since we suspect it creates a weirdly shaped beam image (the emission image looks 0ff ever since we installed it).
 +
 +Disassembled the inner liner tube again to check it for suspected missing apertures - we are indeed missing 2x 3mm (OD) apertures as well as 2x retaining clips.
 +
 +Checked for the weird artifacts and couldn't see them as strong as before, but they are not gone. Emission image looks like a half moon shape still.
 +==== Day 2026-07-18 (q3k, rahix) ====
 +For reference, this is the current sample configuration in the SEM:

 +==== Day 2026-07-16 (q3k, guest) ====
 +Finally replaced the o-ring. In the process, the interlock switch for the top of the column broke. It is jumpered out for now.
 +
 +  * Original switch: [[https://eu.mouser.com/en/ProductDetail/Honeywell/3SX1-T?qs=10P5Hhl%252BD7%2Fotd6%2FZifFJA%3D%3D|Honeywell 3SX1-T]]

 +==== Day 2026-07-11 (q3k, rahix) ====
 +Started work on designing a proper enclosure for the OBI.
 +==== Day 2026-07-10 (q3k) ====
 +Continued work on the OBI. Here's a picture acquired through it:

 +==== Day 2026-07-08 (q3k, hugo) ====
 +New tool worked to get the locknut out. O-ring indeed got destroyed; ordered replacements (it's a 6×2mm). In the meantime, sealed it up again and while not pumping down great, we can still get a good enough vacuum for imaging.
 +
 +Installed the beam blanker:

 +
 +It has an SMC connector, will need to get an appropriate cable.
