Development of a DC Beam Model for the First Prototype of the ESS Virtual Machine

Bolling, Benjamin LU orcid (2019)
Abstract
The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. a rotating Tungsten disk, it will deliver high-flux neutron beams to multiple beamlines at which scientific experiments will be conducted in many scientific disciplines.

To simulate the proton beam and for creating accelerator physics applications, scripts and services, the open source multi-purpose accelerator physics software platform OpenXAL is used. It is based on a pure Java open source development environment, which thus far has been used with an ellipsoidal (bunched) beam to account for space charge effects. The virtual machine (VM) for...

The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. a rotating Tungsten disk, it will deliver high-flux neutron beams to multiple beamlines at which scientific experiments will be conducted in many scientific disciplines.

To simulate the proton beam and for creating accelerator physics applications, scripts and services, the open source multi-purpose accelerator physics software platform OpenXAL is used. It is based on a pure Java open source development environment, which thus far has been used with an ellipsoidal (bunched) beam to account for space charge effects. The virtual machine (VM) for the ESS Low Energy Beam Transport (LEBT) section would profit from having a properly derived continuous (DC) beam model as the beam travelling through the LEBT is DC, and the space charge effect has a strong impact on a low-energy beam.

Thus, in this thesis, a DC beam has been derived, implemented in the OpenXAL and compared against other simulation codes. The results from these comparisons were consistent, suggesting that the deriva- tion and implementation have been properly executed. After the good results from the comparisons, a first prototype of the ESS VM GUI was developed. It covers some basic functionalities and is able to simulate a DC and a bunched beam, and visualize the trajectory of the beam and its envelope. (Less)
