A method for estimating tokamak poloidal field coil currents which incorporates engineering constraints
Abstract
This thesis describes the development of a design tool for the poloidal field magnet system of a tokamak. Specifically, an existing program for determining the poloidal field coil currents has been modified to: support the general case of asymmetric equilibria and coil sets, determine the coil currents subject to constraints on the maximum values of those currents, and determine the coil currents subject to limits on the forces those coils may carry. The equations representing the current limits and coil force limits are derived and an algorithm based on Newton's method is developed to determine a set of coil currents which satisfies those limits. The resulting program allows the designer to quickly determine whether or not a given coil set is capable of supporting a given equilibrium. 25 refs.

This paper proposes a new method for mapping the plasma operational space of a tokamak reactor. The operational space within poloidal field (PF) coil engineering constraints is defined by three parameters, {psi}, {beta}{sub p}, and I{sub p}, which are the magnetic flux supplied by the PF coil system, the poloidal beta, and the plasma current, respectively. It is also shown that the boundaries of the plasma operational space have a onetoone correspondence with the PF coils. The design specifications of the PF coil system are thus related to the plasma operational space.

Poloidal field coil system design for the compact ignition tokamak (CIT). Status report, April 15, 1986
MIT has had the primary responsibility for the PF coil system (WBS G) during the CIT conceptual design. The purpose of this report is to summarize the status of that subsystem design as of April 15, 1986. Coil locations and currents have been defined in a manner consistent with physics requirements (as of February 21, 1986) and system code selections of radial build dimensions, voltsecond, and pulse time requirements (February 12, 1986). Plasma equilibria have been determined for limiter and divertor cases and have driven the design. A design summary is given in Section 2.0 while more detailed discussions aremore » 
Integratedblanketcoil (IBC) concept applied to the poloidal field and blanket systems of a tokamak reactor
A novel concept is proposed for combining the blanket and coil functions of a fusion reactor into a single component. This concept, designated the integratedblanketcoil (IBC) concept, is applied to the poloidal field and blanket systems of a Tokamak reactor. An examination of resistive power losses in the IBC suggests that these losses can be limited to less than or equal to 10% of the fusion thermal power. By assuming a sandwich construction for the IBC walls, MHDinduced pressure drops and associated pressure stresses are shown to be modest and well below design limits. For the stainless steel reference casemore » 
A method for determining poloidal coil configurations for tokamak devices
This paper presents a method for obtaining the locations and currents of the poloidal coil systems for a tokamak, given an desirable magnetohydrodynamic equilibrium for the device. The method involves a simultaneous minimization of the match to the desired poloidal field and the stored energy in the coils, subject to the constraints necessary to achieve decoupling of the equilibrium and inductivecurrentdrive (ohmicheating) systems and to achieve a given coupling of the currentdrive system with the plasma. A compendium of mutual and selfinductance formulas as they apply to tokamak systems is presented, as well as examples of how the method hasmore » 
Limits on m = 2, n = 1 error field induced locked mode instability in TPX with typical sources of poloidal field coil error field and a prototype correction coil, Ccoil''
Irregularities in the winding or alignment of poloidal or toroidal magnetic field coils in tokamaks produce resonant low m, n = 1 static error fields. Otherwise stable discharges can become nonlinearly unstable, and locked modes can occur with subsequent disruption when subjected to modest m = 2, n = 1 external perturbations. Using both theory and the results of error field/locked mode experiments on DIIID and other tokamaks, the critical m = 2, n = 1 applied error field for locked mode instability in TPX is calculated for discharges with ohmic, neutral beam, or rf heating. Ohmic discharges axe predictedmore »
