Workshop on performance variations in H? ion sources 2012: PV H?12
2013
This paper briefly summarizes a workshop held in Jyvaskyla the day after NIBS’12. The half-day workshop aimed at globally capturing the issue of performance variations in H− sources. There was a focus on production facilities and facilities that work under production-like conditions, because there are often high expectations to be met.
Simulation of H- ion source extraction systems for the Spallation Neutron Source with Ion Beam Simulator.
2012
A three-dimensional ion optical code IBSimu, which is being developed at the University of Jyväskylä, features positive and negative ion plasma extraction models and self-consistent space charge calculation. The code has been utilized for modeling the existing extraction system of the H(-) ion source of the Spallation Neutron Source. Simulation results are in good agreement with experimental data. A high-current extraction system with downstream electron dumping at intermediate energy has been designed. According to the simulations it provides lower emittance compared to the baseline system at H(-) currents exceeding 40 mA. A magnetic low energy beam transport section consisting of two sole…
