La ReattivitΓ  dell'Oro, Sintesi Inattesa di Idruro d'Oro in Condizioni Estreme. Un team di ricerca internazionale presso l'European XFEL ha accidentalmente sintetizzato l'idruro d'oro, un composto precedentemente sconosciuto, sottoponendo l'oro a elevate pressioni e temperature. Questa scoperta mette in discussione la tradizionale inerzia chimica dell'oro e apre nuove prospettiva....

`Hooker and his collaborators achieved both goals by directing ring-shaped pulses from an auxiliary laser into a gas cell. These pulses ionized the gas and created a cylindrical plasma channel 110 mm long with favorable radial and axial density profiles. When pulses from the main laser entered the channel, electrons in the low-density plasma at the channel entrance were injected and accelerated in the main body of the channel.`

Creating Fast Bunches of Electrons with Lasers

The judicious shaping of a tube of plasma by one laser enhances the properties of electron bunches accelerated by another.

It felt great finally being back at #RingbergCastle of the @maxplanckgesellschaft to touch base and *snow* with the other members of the @fhi_mpg_de - @Radboud_uni Center for IR-#FreeElectronLaser #Spectroscopy. πŸ”οΈ
