The report is interesting. Glad to see the arcing problem is under control for now.
Does anyone else see the “apple core”? It looks more like wishful thinking than proof. With this image I can’t tell the depth of the filament so it might be light in a more complex pattern that flattens to look like the filament. The image quality is not very good. I’ve seen ~500ps images from lower current PF devices with superior clarity. It’s nice to have the fast framing camera but the set up appears to need some improvement to get better image resolution. Good luck to Fred in pushing beyond 60 um per pixel.
