LIPAc is the prototype hadron accelerator for IFMIF, a neutron source for testing new materials in future fusion reactors, so a very high beam current is necessary and a loss-free design are crucial. In this respect, pre-experimental beam simulations are very important for setting device parameters. By the summer of 2024, we were able to confirm that the simulation and experimental results matched for beam size very well and achieved a beam duty cycle of 8.75 % with current of 119 mA. In the presentation, we will report on reliability of simulation and how the calculated and measured results matched up. But we also observed some activations at several locations, which may be due to the beam halo. We will also report on simulation studies of the halo.
