 Neutral particle analyzers measure the energy spectrum of fast neutrals in the plasma
C-2W EM-NPA View Angles
 β€’ Primary source of outbound fast neutrals is charge exchange:
𝐻' & + 𝐻 ' β†’ 𝐻' ' + 𝐻 &
β€’ The C-2W EM-NPA uses a He gas stripping cell to ionize the fast neutrals
β€’ It then uses tunable 𝐸 βˆ₯ 𝐡 fields to separate fast ions by energy and isotope according to Lenz’s law:
𝐹⃗ = π‘ž 𝐸 ( ) * + 𝑣⃗ Γ— 𝐡 ( ) *
β€’ The ions impact a set of microchannel plates (MCPs) creating the measured signal
