There has been concern that full gyro-orbit orbits may be subject to large pitch angle scattering in the sharply varying magnetic fields such as in WHAM[2], and this could cause fast ion loss into the mirror loss cone. Using the MCGO Monte Carlo orbit code, the full deuterium orbits were following for collisional slowing down times. Orbits appear to be in the QLM Quantum-Like-Mode, falling in to discrete states, and at least for the examined orbits the resulting diffusion is limited and does not appear large.
