Open and emerging control problems in tokamak plasma control
2008 47th IEEE Conference on Decision and Control, 2008The tokamak concept for magnetic confinement of fusion plasmas is now quite mature scientifically. This maturity is evidenced by the ongoing worldwide effort to design and construct an internationally supported multi-billion dollar experimental tokamak called ITER, whose purpose is to demonstrate the scientific and technical feasibility of fusion ...

A plasma opening switch controlled by a drifting plasma
1990 Plasma Science IEEE Conference Record - Abstracts, 1990Summary form only given. At the conceptual level the density controlled opening switch (DCOS) under investigation is a vacuum device in which both conduction and opening mechanisms are controlled by an externally injected plasma. The development of the DCOS has involved a substantial program of experiments focused on (1) sustaining control over ...

IEEE Control Systems, 2006
This paper describes the ITER tokamak from the standpoint of operation, with emphasis on the plasma control system. It discusses the plasma operation scenario sequence that is carried out in feedforward control mode, and presents the overall feedback control system, which can be roughly separated into two weakly coupled control loops.

The accurate control of the plasma position is essential in a tokamak reactor, where a large plasma current has to be created and maintained for several minutes. In the INTOR study1 it has been shown that an elongated plasma cross-section is advantageous in many respects for a reactor.

Plasma Cytokine Levels in Migraineurs and Controls
Headache: The Journal of Head and Face Pain, 2005Background.—The vasoactive peptide, calcitonin gene‐related peptide (CGRP), is released from primary afferent neurons in the trigemino‐vascular circulation during migraine headache. CGRP at physiological concentrations and possibly via stimulation of its selective receptors on T‐cells, triggers the secretion of cytokines.

Magnetic control of a tokamak plasma
2008he plasma in a tokamak is magnetically confined through electromagnetic fields generated by a set of poloidal field coils, with feedforward nominal voltages or currents based on an approximate plasma model. Therefore, feedback control is necessary. A good magnetic control is essential for achieving good performance in present devices and expected to be

A genetically controlled esterase in rat plasma
Biochimica et Biophysica Acta (BBA) - General Subjects, 1966Abstract The esterases present in rat plasma were studied by starch-gel electrophoresis, The dominating esterases were arylesterase (EC 3.1.1.2) and carboxylesterase (EC 3.1.1.1), both types migrating close to the albumins, and the slower moving cholinesterase (EC 3.1.1.8). A “pre-albumin esterase” was present in certain animals.

Plasma flow control, based on the plasma aerodynamic actuation, is a novel active flow control technique to improve aircrafts’ aerodynamic characteristics and propulsion efficiency. Plasma flow control has drawn considerable attention and been used in boundary layer acceleration, airfoil separation control, forebody separation control, turbine blade ...
