First turns in MAX IV 1.5 GeV storage ring

First turns in MAX IV 1.5 GeV storage ring

Today beam was injected from the linac to the 1.5 GeV storage ring and for the first time several turns in the storage ring could be detected. The image shows the BPM sum signal from the third BPM in achromat 1. It clearly reveals three beam passages separated by 320 ns, the ring’s revolution period. At this point a radiation survey will be conducted first before beam commissioning continues. The next steps will be to achieve many turns, trigger the injection kicker and eventually capture beam in the RF bucket thereby hopefully enabling first stored beam.
