Description

The European Spallation Source (ESS) is in the final stages of commissioning its linear accelerator (linac), which aims to deliver a high-power proton beam for neutron production. Understanding the dynamics in the machine and comparing measurements with the model can provide a deeper insight into the machine’s performance and help avoid possible issues when we start ramping up the power. Several techniques are available for measuring both transverse and longitudinal emittance, making comparison and benchmarking important. At ESS, existing transverse emittance measurements show some variation between methods and differ from the design values. This work investigates possible sources of these discrepancies. In addition, the feasibility of deriving the longitudinal emittance using available beam diagnostic tools at the ESS linac is explored.
