Summary:
A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II,
giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times.
The advance enables scientists to explore atomically thin materials, nanostructures,
and ultra-dilute samples with remarkable speed and sensitivity.

Nice PCBs :-)

Transition edge sensors are fascinating. You get single-photon
sensitivity and some energy resolution at the same time.

There is more info on those here:

Now if you could put some Peltiers in seris the cooling could be simple?

You have to get down to a few kelvin, which is out of reach for Peltier coolers.

I see -90C on youtube
https://www.youtube.com/watch?v=ImiSpAjKjss

I see no reason not to put more in series?

I have whole bunch of small Peltier elements from ebay..
Have only tried a few in series, makes nice voltage sources too.

Who knows, but I also have super cooler:
https://panteltje.nl/pub/cryo/index.html

It was used to cool a superconducting filter for telecom towers.
You can make liquid nitrogen, so rocket fuel with it too,
This guy gave me the idea to buy one on ebay and try it:
https://benkrasnow.blogspot.com/2008/08/diy-liquid-nitrogen-generator.html?m=1

Useful for anti-gravity experiments like this:
https://en.wikipedia.org/wiki/Eugene_Podkletnovs

Home lab is cool

And we are having a heatwave here...
Highest temperatures ever measured in the UK and France too.
Code red here for tomorrow.
https://www.knmi.nl/nederland-nu/weer/verwachtingen
Does not seem to affect me much, still have my sweater on.
-40 C and I was walking in jeans going for a job application long ago.

But some people seem to be dying from +35 C

Peltier junctions are shockingly inefficient, and stacking them means
having a lot in the first stage to get rid if the waste heat from a
single second stage unit.

Who knows, but I also have super cooler:
https://panteltje.nl/pub/cryo/index.html

It's a Stirling engine.

It was used to cool a superconducting filter for telecom towers.

Home lab is cool.

If you have liquid nitrogen floating around, about 77K.

You have to be pretty unhealthy for 35C to kill you, but it can happen.
Before global warming, cold snaps killed more vulnerable people than
heat waves, but that's no longer true.
