Design and construction status of the TPM-1U tokamak

TPM-1U is a small size tokamak, with a vacuum vessel of 0.15 m minor radius and 0.4 m major radius, with an expected magnetic field in the torus centre of 0.5 T and a plasma current above 150 kA. One of the goals of the TPM-1U is to establish the scientific and technological base for the study of magnetically confined high temperature plasmas in Mexico, and help bring cohesion to the efforts in this field that have been scattered to date. Another goal is to contribute to the generation of high level human resources that can help the community grow in size. In addition to these two strategic goals, the machine will also have technical and scientific goals such as plasma-wall interaction studies, development of new diagnostics and exploration of new magnetic topologies. In this work, the design for the pulsed power system that will be used to feed the set of toroidal coils and design considerations for the central solenoid will be presented. Calculations for the dimensioning of the central solenoid used for ohmic heating are also presented, as well as preliminary considerations for the implementation of microwave power injection into the plasma.
