Phase-space tomography in magnetically confined plasmas

In this paper, a tomography approach aiming at reconstructing phase-space structure is proposed. For the resolved diagnostic system, signal must be decomposed in real-space, velocity-space, and time; therefore, it challenging to obtain sufficiently high intensity single detector bin. To overcome difficulty, three different sets of data having integration directions time are simultaneously used, reconstruction original attempted by tomographic manner. The proposed method demonstrated using synthetic dataset actual setup Large Helical Device. Time evolution perturbation induced Landau damping, which caused energetic particle-driven magnetohydrodynamic bursts, successfully reconstructed method. Robustness against realistic noise also presented.
