Query: Deep modelling of plasma and neutral fluctuations from gas puff
  turbulence imaging   The role of turbulence in setting boundary plasma conditions is presently a
key uncertainty in projecting to fusion energy reactors. To robustly diagnose
edge turbulence, we develop and demonstrate a technique to translate brightness
measurements of HeI line radiation into local plasma fluctuations via a novel
integrated deep learning framework that combines neutral transport physics and
collisional radiative theory for the $3^3 D - 2^3 P$ transition in atomic
helium. The tenets for experimental validity are reviewed, illustrating that
this turbulence analysis for ionized gases is transferable to both magnetized
and unmagnetized environments with arbitrary geometries. Based upon fast camera
data on the Alcator C-Mod tokamak, we present the first 2-dimensional
time-dependent experimental measurements of the turbulent electron density,
electron temperature, and neutral density revealing shadowing effects in a
fusion plasma using a single spectral line.
