TL;DR: In this paper, the authors investigated the effect of high-density conditions in a wide range of plasma currents and magnetic fields and found that the line-averaged densities at the disruptive limit increased more than linearly with the toroidal field, while no dependence on plasma current was found; in fact, the maximum density of 4.3 × 1020m−3 was reached at B = 8 T even at the minimum current of 0.5 T, corresponding to twice the Greenwald limit.

TL;DR: In this article, a real-time data acquisition and elaboration system is implemented to control the new ECH launcher recently installed at FTU (Frascati Tokamak Upgrade), aimed at controlling different kinds of magnetohydrodynamic instabilities, in particular the deleterious 3/2 and 2/1 (neoclassical) tearing modes, and the saw teeth period in order to prevent the seeding of NTMs.

New diagnostics for density measurement on Frascati Tokamak upgrade
TL;DR: In this paper, a CO2/CO scanning interferometer and a time-of-flight radar (denominated refractometer) were used to measure the density profile of the plasma.
