Guess who's just been told the company probably won't hire them after uni 🥳 I never saw myself staying here for the long term, but with the current job market and ✨️ overall situation ✨️ it would have been nice to start out with some security. My next mid term goal was ending up at some accelerator facility like the GSI, I'm guessing that is getting moved up now. Do I know anyone here in Darmstadt?

@StripeyYena@chaosfurs.social Every diff system I know has a pot for LN2, but I don't think I've ever seen it actually get used lol. I wonder how much better it would be. But then again life in general would be better if I had a constant supply of LN2 at my disposal

Last week a Biergarten here in munich made the news because someone found a "hotspot" with their geiger counter:
https://www.br.de/nachrichten/bayern/angebliche-radioaktive-strahlung-einsatz-im-englischen-garten-in-muenchen,VI75G4A

OF course I had to go there and check it out myself!
The entire area was slightly elevated, barely noticeable and well withing reason for a change in ground composition. That hotspot must have been a tiny rock.

In the end I got a nice ~30 km bike tour and a good breakfast out of it.

Angebliche radioaktive Strahlung: Einsatz im Englischen Garten

Weil ein Passant auf seinem Messgerät im Norden des Englischen Gartens in München radioaktive Strahlung gemessen haben will, ist es dort zu einem Einsatz gekommen. Das Ergebnis: Entwarnung.

@StripeyYena@chaosfurs.social Delightful. Here it's always stuff that's been forgotten about since the 80s, so nobody knows what the hell it is or where it came from. But IIRC you work with way shorter lived isotopes, so I guess that argument can't be made here

If so I'd be very happy about a couple of them, it's always great to have multiple PMTs of the same type. I'll gladly donate to your space, plus shipping costs and all.

I wish nothing more than for people to stop making up "equations" to explain things to people in STEM. It's utter nonsense and only leads to further confusion. It does not make you look smart in any way.

@ozon Hm, very interesting! Judging by the floor and a few other details it might very well be the same machine, but it looks like it underwent an overhaul. The blog post I linked said it will be torn down, maybe instead it got refurbished? I can't find a way to contact the blog author, or the upolader of this video :/

Replying to

@ozon @PatrickHerd That's why some argue you need your brush to spray the belt with the counter-electrode not touching the belt so it can't transfer a mirror charge which cancels out the spray charge. Then there are variants with a grounded brush followed by a brush at HV to first neutralize all charges going down and then charge the belt going back up.
