HIBP probe diagram

At TJ-II, the advanced Heavy Ion Beam Probe can simultaneously measure the plasma electric potential φ, the electron density ne, the electron temperature Te, and a poloidal magnetic field component Bp at a point inside the plasma. [1] [2] [3] [4] [5] This point can be scanned through the plasma cross-section by varying the deflection potentials (active beam control).
