Neutral Be emission 457nm (injection) The ERO modelling is in a good agreement with experiment (PSI-2008) 02/09/2010 D.Borodin | Oak Ridge WS | Forschungszentrum Jülich No 14
Radial profiles at oven (z=150mm): Be Deviations of modelling from experiment: 1) BeI max. shifted to seeding location 2) BeII profile too narrow 3) Absolute values of BeI intensity and ratio of BeII/BeI deviate by factors, which are different for various plasma conditions . . . Possible explanations: 1) Uncertainties in plasma parameters (input) – e.g. plasma column width too large?.. 2) Atomic data, Be-D molecules, metastables, . . . 02/09/2010 D.Borodin | Oak Ridge WS | Forschungszentrum Jülich No 15
