Discharge cleaning and wall conditioning in a Novillo Tokamak
Journal of Nuclear Materials, 2002Abstract Our Novillo Tokamak is a small toroidal device magnetically confined defined by the main design parameters: Ro=0.23 m, av=0.08 m, ap=0.06 m, BT=0.05–0.47 T, Ip=1–12 kA, ne=1–2×1013 cm−3, Te=150 eV, Ti=50 eV. For the initial discharge chamber cleaning we have often used vacuum baking up to 100 °C and then conditioning using Taylor discharge ...

Plasma-Wall Interaction Delay Time in Novillo Tokamak
AIP Conference Proceedings, 2006In this work we report the plasma‐wall interaction delay time and the impurity evolution process in Novillo tokamak. The main design parameters of the Novillo tokamak are: mayor radius Ro = 23 cm, minor radius av = 8 cm, plasma radius ap = 6 cm, toroidal field BT = 4.7 kG, plasma current Ip = 12 kA, plasma density ne = 1–2 × 1013 cm−3, electron ...

Comparative modelling of X-ray backscattering in the Novillo tokamak
Radiation Measurements, 2001Results of X-ray backscattering studies on the Novillo tokamak using thermoluminescent dosimeters (TLDs) are presented. Dose measurements were carried out on the equatorial plane of the tokamak along 12 radial directions. The backscattering can be due to the interaction of the radiation with the surrounding walls.

Electrical probe diagnostic with fast data acquisition systems of the Novillo tokamak
AIP Conference Proceedings, 2001This paper describes the electrical probe diagnostic system used to measure the relevant parameters of the plasma column generated in the Novillo tokamak, and an inexpensive and fast data acquisition system that consists of 16 independent channels, 8 bit resolution, sampling frequency of 500 kHz, and 8 kword memory per channel.

Study of Electron Energy in the Chemistry of the Glow Discharge Plasma in the Novillo Tokamak
Fusion Technology, 2001The evaluation of the electron temperature, density, and plasma potential in a glow cleaning discharge hydrogen plasma in the Novillo tokamak is presented. The objective was to investigate the plasma conditions allowing the removal of impurities from the vacuum vessel, thus avoiding the formation of other chemical compounds that could remain adhered to

Reconstruction of Magnetic Field Surfaces of the NOVILLO Tokamak by means of the 3D-MAPTOR Code
AIP Conference Proceedings, 2008A 3‐D code has been developed in order to simulate the magnetic field lines in circular cross‐section tokamaks. The toroidal magnetic field can be obtained from the individual fields of circular coils arranged around the torus, or alternatively, as a ripple‐less field, as well as the vertical field coils, and divertor‐like coils.
