ESS Achieves Beam on Dump: Accelerator Commissioning Underway
The European Spallation Source ERIC (ESS) has successfully achieved Beam on Dump, a major accelerator milestone and an important step towards commissioning of the entire ESS facility.
For the first time, protons have been accelerated to the correct energy and delivered all the way from the Ion Source to the Tuning Beam Dump – 542.5 metres down the accelerator tunnel. For the research facility currently under construction outside Lund, Sweden, this achievement demonstrates that the ESS accelerator is functioning as an integrated system, from source to dump. It is the culmination of years of
