Our eFIB-SEM (as per Xu et al. 2017 https://elifesciences.org/articles/25916 ) runs 24/7 for up to 8 weeks, when it runs out of source. And it's essential that it does so, uninterrupted, since it's imaging at nanometre resolution, milling 2 nm slices at a time with an ion beam and then repeatedly imaging the block face. The process is unsurprisingly very sensitive; was hard enough to overcome the reheat cycle of the instrument itself (every 60 hours or so) by detecting it, de-engaging the beams and then seamlessly re-engaging with the block face.
A brief video of the kind of data we acquire:

"The first synapse was visualized using electron microscopy in the mid–1950s, although parallel work and delicate egos make it difficult to determine with certainty the first researcher to actually see one." – Alexandra Balwit https://www.asimov.press/p/barcoding-brains
Neuroscientists are human after all.

https://www.biorxiv.org/content/10.1101/2023.10.05.561103v1.abstractTurn up the imaging rate of your scanning electron microscope by only imaging at high resolution the areas of the image necessary to resolve ambiguities in the low-res image. Motivated by the need for high-throughput but inexpensive imaging for #connectomics.

Been working on some electrode patterns, starting to get some nice results. 🥳
Edges are a bit fuzzy/burry since I'm sputter depositing rather than something more line-of-sight like thermal evap. Getting a better dep method is high on the todo list.
Resist stack is an MMA/PMMA bilayer, substrate is silicon + ~100nm CuO, and electrodes are 150nm of aluminum via lift-off.
In theory, these should act as metal-semiconductor-metal photodetectors. Unsure if my test gear is sufficient though, might need to upgrade my electronics a bit. We'll see! 🤞
