In this article, some diagnostic systems and the preliminary results of the IR-T1** (Iran-Tokamak 1) are presented. Different diagnostic methods, including an array of soft X-ray detectors, visible spectrometer, electron cyclotron emission detector and electromagnetic measurement systems have been used and the hard disruptive instability occurring in the IR-T1 plasma during an ohmic heating...

The potential formation of multi-mega-ampere beams relativistic "runaway" electrons (REs) during sudden terminations tokamak plasmas poses a significant challenge to the tokamak's development as fusion energy source. Here, we use state-of-the-art modeling disruption magnetohydrodynamics coupled with self-consistent evolution RE generation and transport show that non-axisymmetric in-vessel coil ...

The paper presents the improved FCDI plasma equilibrium reconstruction algorithm implemented at Globus-M2 tokamak. has been to be able operate in real time. FCDI-FF (Fixed Filaments) operation mode was added, which is modeled by current filaments fixed positions. New user interface for displays reconstructed separatrix and contours of internal magnetic surfaces, poloidal flux distribution, grap...

This paper is aimed at creating a vacuum and a gas handling subsystem. The new vacuum and the gas handling subsystem was developed at IPP/Prague after the COMPASS tokamak reinstallation. It was necessary to build a system which can operate 24/7 and be fully autonomous. A firmware programmed in the C programming language controls devices connected to the vacuum and the gas handling subsystem. Th...
