The supermassive black hole that lies
At the center of our Milky Way skies
Sent out huge bursts of light
And they shone into the night
Unleashing radiations and surprise

Here's a (ultra- ), taken from within the @DESY into the crowd of visitors.

On the left, Prof. Salditt explains the setup and the measurement scheme. In the bottom part, left of the yellow knob, is the sample tower; slightly left from the centre, parts of the (blue camera labelled “PCO”) are visible; towards the rear, a big evacuated flight tube help the to reach the second detector bench.

Also, lots of hang around.

The by the Platform is coming to an end. Soon, the last talk will close, after the summary we'll have a networking lunch – and therefore also visit the experiment currently receiving at the P10 beamline.

I am here analysing samples in the hunt for events. Key steps are Sr maps so we can build precise chronologies in our annually laminated samples, and maps of metals, because they're not always distributed evenly across growth layers. Here we can see spotty iron distribution in the sample.

Just a warning, there might be some noise on this account these days, about the Workshop “Scientific Opportunities with very Hard Radiation” starting very soon @DESY .

Just picked up by badge; so, where's the coffee?

H.L.Smith demonstrates the first ever X-ray generator in 1896, that would produce X-Rays, the very first image was that of a hand, and it would be demonstrated to the public later in 1904.

Wilhelm Röntgen publishes his paper detailing the discovery of a new type of radiation in 1895, which would be called as X-Rays. One of the major landmarks in medical science, for which he got the first ever Nobel in Physics in 1901.

In December 1895, Wilhelm Röntgen announced to the world the discovery of an unknown and invisible form of radiation: 💀, as he called them. The importance of this discovery in the field of medicine earned him the first in Physics in 1901 🙌

On-site beam time at SLAC National Accelerator Laboratory means running into all the great SSRL folks and collaborators who are also on-site! Fun science times going on at SSRL (and some holiday cheer)!
