Abstract-the formation of transport barriers under electron cyclotron resonance heating and current drive in the t-10 tokamak is studied. in regimes with off-axis co-eccd and qL<4 at the limiter, a… Continue Reading
Development of the gyrotron system for ITER is based on solution of many very difficult scientific and engineering problems. At present the main purpose of the system modification is an enhancement… Continue Reading
The results of T-10 experiments on the 'density pump-out' effect research, i.e. the escape of particles from the zone of on-axis electron cyclotron resonance heating (ECRH) to the plasma periphery… Continue Reading
Pre-ionization with help of Electron Cyclotron Resonance (ECR) waves and ECR assisted plasma start-up are considered as useful tools for discharge initiation in next step devices, in particular in… Continue Reading
During last years several new gyrotrons were developed at IAP/GYCOM. The main ITER requirements to a gyrotron have been demonstrated: 170 GHz frequency, 1MW power, 1000 seconds pulse duration, 53%… Continue Reading
The paper presents development status of a gyrotron setup for ITER. Twenty four such setups are to be used for heating and current drive in ITER plasma. The setup includes a gyrotron in a… Continue Reading
The plasma stability and confinement have been investigated through control of the safety factor profile q(r) by the electron cyclotron current drive in the T-10 tokamak. The regimes with dq/dr0 and… Continue Reading
Recent test results of newly designed 1.5-1.7 MW/170 GHz gyrotron which is considered as a possible RF source for the ITER program are presented.
Complete non‐inductive current drive from a combination of ECCD and bootstrap has been achieved in a regime with Ip∼75 kA. At higher currents, Ip∼175 kA, up to 110±15 kA was generated by ECCD.
The results of the electron cyclotron heating (ECH) experiments in T-10 are presented. An 11-tube gyrotron set-up with a total power of 4 MW was used in the experiments. The set-up consists of two… Continue Reading
