The feasibility of the visible camera system EDICAM installed on JT60-SA for runaway electron radiation detection was investigated recently [1] by simulating disruptions for a JT60-SA like tokamak with DREAM [2] and using the resulting distribution function in the synthetic synchrotron diagnostic framework SOFT [3] to calculate the radiation image with the EDICAM camera parameters. The recent first campaign of JT60-SA and the success of the simulations in [1] motivated further investigations of the detection capabilities of the EDICAM system for small current cases, and disruptions with high pitch scattering of the runaway electron population. The simulations shown here were done with the purpose of comparison with experimental results from the first campaign, but experimental results will not be presented. References: [1] S. Olasz et al.
