Stability and optical quality of liquid crystal films as high repetition rate plasma mirrors in staged laser-plasma accelerators
Staging multiple laser-plasma accelerators (LPAs), each driven by its own laser pulse, is a promising technique for reaching higher particle energies than achievable in a single LPA. However, introducing subsequent laser pulses for post-acceleration in staged LPA geometries presents a significant challenge for conventional optics. Due to the focused, high-intensity nature of the laser beam interacting with the electron beam, the fluence on the coupling mirror surpasses the damage threshold of a…

#1980smoviestaughtme that "saving time" is meaningless

The complexities of life mirror the narratives in military history films I cherish. 🎥 There’s beauty in how structured storylines make sense of chaos. Has a film ever reshaped your life view? Share those cinematic masterpieces that linger in your thoughts! #MovieMagic #HiddenGems

Da sind sie wieder. Hab schon gewartet, wann die #Raupen auftauchen. Den #Kohlweißling hatte ich bereits vor Wochen beobachten können. Eigentlich soll der ja an die #Kapuzinerkresse geh…

"Whenever anyone asks me for advice, I tell them: we don’t realize how deeply the nine-to-five fractures us. The weekends, the holidays, the fixed friend group—whatever rigidness exists in your behavior will exist in your perception, and it will exist in your ability to think critically."
Victoria Brugger, "Last Words of an Ego on Death Row"

Last Words of an Ego on Death Row
Hello.I don’t know who you are. But I hope we meet in the next pages—across whichever dimension I had to cross to embody these feelings.This is not a book. It is not a journal.It is the autopsy of an ego and the birth certificate of the woman I am today.It carries the blueprints I bled for: how to build something from nothing, how to love yourself when the mirror is a battlefield, how to decode the nature of existence and drag purpose out of the dark.But more than all of that—this is my b…

First Electron Acceleration in a Tunable-Velocity Laser Wakefield
We present the first experimental confirmation that a laser-wakefield accelerator produced by a flying focus pulse is able to maintain the coherent structures necessary to accelerate electrons to relativistic energies. Through a combination of spatio-temporal near-field shaping of the beam and focusing with an axiparabola - a long-focal-depth mirror that produces a quasi-Bessel beam - the propagation velocity of the wakefield is tuned to control the maximum electron energy achievable. The exper…

The beta decay of Tz=-2 64Se and its descendants: the T=2 isobaric multiplet
In this paper we present our results on the decay of 64Se. It is the heaviest Tz=-2 nucleus that both beta decays and has a stable mirror partner Tz=+2, thus allowing comparison with charge exchange reaction studies. The beta decays of 64Se and its descendants were studied at the RIKEN Nishina Center (Tokyo, Japan) following their production in the fragmentation of 78Kr on a beryllium target. Beta-delayed gamma-ray and particle radiation was identified for each of the nuclei in the decay chain …
