Pitch-Angle of CX Loss Distribution Contains Information About Fast Ion Population
• New detectors are designed to measure limited information on the pitch-angle of CX neutral losses.
• Pitch angle contains some information about radial profiles of fast ions and neutral gas.
• Analysis by comparison to simulation.
Idealized Circular Orbits:
⍺ depends on orbit radius, R.
Orbits from Monte-Carlo Simulation:
More complicated but ⍺ distribution still has information on radial profile.
