    Abstract

    Using infrastructure from the old TPM-1 tokamak in Mexico, there is an ongoing project to bring it back into operation, but with important upgrades. One of the main planned improvements will be the substitution of the continuous winding used to generate the toroidal field (TF) with a set of discrete circular coils. The new toroidal magnetic field configuration should also allow stable operation of the machine at plasma currents of up to 50 kA for 30 ms. At this design stage, decisions regarding number and characteristics of the coils and power delivery strategy to them need to be addressed. In the present paper, a study regarding the parameters required for the generation of the adequate TF are presented, including the process for determining number of TF coils, their size and position, the required current pulse for operation, and a potential strategy for generating such pulse based on passive pulse-forming networks.
