Great news from Axel Neumann, iSAS Work Package 1 Convener and SEALab project manager at HZB:

The SEALab team has achieved a breakthrough by generating an electron beam from a multi-alkali (Na-K-Sb) photocathode and accelerating it to relativistic energies in a superconducting radiofrequency accelerator (SRF photoinjector).

bERLinPro project inspiring the SEALab team, depite numerous challenges, has enabled this world first with promise to open up the accelerator physics landscape of today.

Among the various applications raised: free-electron lasers, energy recovery linac (ERL) class accelerators, detector development and ultrafast electron scattering experiments (UED).

Congratulations for this beautiful work!
