摘要：
A synthetic fast-ion loss (FIL) detector and an imaging Heavy Ion Beam Probe (i-HIBP) have been implemented in the 3D hybrid kinetic-magnetohydrodynamic code MEGA. First synthetic measurements from these two diagnostics have been obtained for neutral beam injection-driven Alfven Eigenmode (AE) simulated with MEGA. The synthetic FILs show a strong correlation with the AE amplitude. This correlation is observed in the phase-space, represented in coordinates (P-phi, E), being toroidal canonical momentum and energy, respectively. FILs and the energy exchange diagrams of the confined population are connected with lines of constant E-', a linear combination of E and P-phi. First i-HIBP synthetic signals also have been computed for the simulated AE, showing displacements in the strike line of the order of similar to 1 mm, above the expected resolution in the i-HIBP scintillator of similar to 100 mu m.
