Abstract
One of the most important design elements of a tokamak is a vacuum discharge chamber, which has specific requirements related to the induction method of plasma generation and, accordingly, the presence of variable magnetic fields that additionally affect the chamber. In addition, the chamber should not only provide the possibility of creating and retaining current plasma in it, but also provide the possibility of diagnosing its parameters through the appropriate pipes. The small spherical tokamak is under construction at MEPhI, intended for both educational and research purposes, has an extensive program of such research, so the discharge chamber must not only quickly create a vacuum, withstand variable magnetic fields, but also be convenient for measuring. This paper describes design, calculations of mechanical stability and results of manufactured chamber tests.
Supporting agencies: Calculations of the vacuum chamber were made within the framework work under contract 313/1755-D dated September 20, 2019 between NI- YAU MEPhI and JSC “Science and Innovation” State Corporation Rosatom at R&D on the topic “Project development and modernization small spherical tokamak for training highly qualified specialists in the field of Research Institute "Plasma Physics". The vacuum chamber is manufactured in part by funds from voluntary donations from Pyramid Vacuum LLC and a graduate of the Department of Plasma Physics MEPhI Malafeev Oleg Arkadievich
