NIO1 is a compact radio frequency (RF) ion source designed to generate a 60 kV-135 mA hydrogen negative ion beam and it aims at continuous operation, which implies a detailed thermo-mechanical analysis of the beam-facing components, in particular the accelerator grids. A 3D analysis of the entire NIO1 beam has been performed for the first time with a fully 3D version of EAMCC, a relativistic particle tracking code based on the Monte-Carlo method for describing the transport of particles inside the accelerator and the main secondary particle formation processes responsible of relevant heat loads on the accelerator grids. The main results are presented in this report, after a brief description of the device.
