The Diocotron Instability in the Trapped Electrons Experiment T-REX and its Relevance to Electron Clouds in Gyrotron Guns

arXiv:2606.02217v1 Announce Type: new Abstract: Gyrotrons are essential for electron cyclotron resonance heating (ECRH) in fusion reactors, making their efficient operation crucial for fusion energy. Past experiments revealed instability issues due to trapped electrons in the magnetron injection gun (MIG) region, causing undesired currents and operational failures.

Rex: A Family of Reversible Exponential (Stochastic) Runge-Kutta Solvers

Announce Type: replace Abstract: Deep generative models based on neural differential equations have become state-of-the-art for many generation tasks. These models rely on ODE/SDE solvers that integrate from a prior distribution to the data distribution; in many applications it is also highly desirable to integrate in the inverse direction. Standard solvers, however, accumulate discretization errors that prohibit exact inversion, an inaccuracy that is unacceptable in precision-critical...

‘Bowie compared us to T Rex. Couldn’t get any better’: the Mekons on how they made Where Were You?

The Mekons discussed the inspiration behind their song "Where Were You?", stating it was about loneliness and contrasted with the prevailing macho rock mentality of the era. Members of the band, who were art students at Leeds University, were influenced by bands like The Clash after seeing them perform.

‘Bowie compared us to T Rex. Couldn’t get any better’: the Mekons on how they made Where Were You?

‘It’s about loneliness, really. It was the total opposite of that “It’s Friday night, let’s have sex” macho mentality that was in most rock music at the time’Most of the people who started the Mekons and Gang of Four were on the same fine art course at Leeds University. In December 1976 we went to see the Anarchy tour at the nearby polytechnic.

We may finally know why dinosaurs like T. rex evolved tiny arms

Five different groups of predatory dinosaurs independently evolved disproportionately small arms, and it seems they did so because their heads became so large and powerful

Tentacles, pointy teeth and the T-rex of the sea: the Natural History Museum on beasts that once ruled the oceans

The Natural History Museum has launched a new exhibition, Jurassic Oceans, featuring prehistoric marine life. The display showcases fearsome creatures, such as a 23ft plesiosaur, while also warning about the current impact of warming waters on marine ecosystems.

T. rex had massive jaws but tiny arms: Scientists now know why

At Melbourne's last video rental store, physical media never died

Film and music enthusiasts turn to physical media Sun 7 Jun 2026 at 4:30am It feels like the 1990s. Warm light, small groups, rows of titles, stacks of discs, a clacking of a case closing, and a giggle from the shopkeeper. Enjoy," smiles Rex Rekhi, finalising a sale during a Friday lunch time rush at his store in the middle of Melbourne's CBD.

Lab-grown Tyrannosaurus leather: More chicken than dinosaur?

A handbag is promoted as the "world's first T. rex leather product". But scientists are questioning its authenticity.
