The SLS consists of a 100MeV linac, a 2.7GeV booster synchrotron with 9nm horizontal emittance and the storage ring (SR). The old 12-TBA SR with 5nm horizontal emittance operating at 2.4GeV was turned off in 09/2023 after 22 years of successful user operation. In course of the SLS 2.0 upgrade project the 288m circumference SR has been replaced by a 2.7GeV 12-fold 7-bend achromat lattice with a...
An ultrafast strong field terahertz(THz) lightsource will be built at the Hefei National Laboratory. This lightsource aims to characterize the multi-quantum collective behavior of the quasiparticles and enable the cutting-edge exploration of materials for the quantum information technique. To meet these goals, the lightsource needs to cover the electromagnetic spectrum of 0.1-10THz, the...
The versatile 1.3 GHz superconducting radio-frequency (SRF) gun at HZB succesfully generated first photoemission beam from a high quantum efficiency (QE) multi-alkali photocathode. This demonstrates worldwide first beam operation of a SRF gun at high repetition rate and with a robust multi-alkali Na-based photoemissionn source. The setup of the test and all sub-systems is described. The latest...
