#synchrotron

Continued thread

Synchrotron light is conventionally defined as the emission from accelerated ultra-relativistic electric charges.

Ultra-relativistic means that the speed of the charge is extremely close to the speed of light, v ≈ c.

The first part of the book deals with introductory concepts, starting from special relativity, and moving on emission from accelerated charges, then #synchrotron emission from charges in circular and undulating trajectories.

In a bit of shameless self-promotion, I'm proud to announce that I've a new book out!

"Synchrotron Light: a Physics Journey from Laboratory to Cosmos", was written together with my co-author Prof. David Paganin and published by Oxford University Press.

Target audiences include users of terrestrial synchrotrons, those studying astrophysical sources of synchrotron radiation, and high-energy physicists.

In the next few days/weeks, I'll introduce some of the topics and other tidbits in this thread.

@janw At our institute we switched to zfs for /home (including group folders) back in … can't really remember … maybe already 2009?
For us, especially the FS per user and efficient way to do snapshots + send these to remote storage is a big advantage. The pool has 300T size (alloc 152T).

For $reasons the “large” data (#synchrotron and in-house experiments) lives on the data centre's ceph cluster, we use approx 10× there.

Managed by experts, yes; but for own-hosted ZFS we have a good feeling.

Gleich geht es los: die DAPHNE 4 @NFDI -Jahrestagung, am #HZB in Berlin-Adlershof! Unsere Sticker und Flaschenöffner sind schon da, das Mittagessen wird aufgebaut.

Aktuell läuft eine Führung durch das #Synchrotron; nach der Begrüßung kommen die Facility Updates und die Use Cases-Flashtalks. Anschließend Poster-Sitzung.

Zum Wochenende kündigen sich die Anträge auf Strahlzeit am #MAXIV-#Synchrotron in #Lund an, die ich bis zum Monatsende begutachte; erste April-Woche ist dann die lange Videoschalte des Komitees, welchen Experimenten wir die verfügbare Zeit zuweisen können.

“You'll have two to three weeks” zum Lesen der Anträge, aber ich bin in der Zeit ungefähr vier Wochen dienstreisend 🤣

Was ist ErUM Data?

#ErUM sind die #BMBF-Projekte zur Durchführung aufwändiger Experimente, insbesondere an Großforschungseinrichtungen (CERN, DESY, Teleskope, …); die Wissenschaftler*Innen haben sich in acht Komitees¹ organisiert.

ErUM Data fokussiert sich parallel zu den experimentellen Methoden auf algorithmische Methoden der Datenauswertung, insbesondere in den Bereichen Big Data und Machine Learning.

¹„wir“: KFS und KFN, die Komitees zur Forschung mit #Synchrotron- und #Neutronen-Strahlen
