A Density-Capped Confinement Vessel: Sizing a Magnetic Bottle Whose Operating Point Sits Below the Aldred Density by Construction

This paper presents a complete design study of the device is a toroidal magnetic confinement vessel, scanned over minor radius, operating a deuterium-tritium plasma at fifteen kiloelectronvolts and a stated density of ten to the twentieth particles per cubic metre, derived from stated assumptions and computed throughout by the accompanying script. The stated plasma pressure is 480.78 MPa, balanced by a field of 34.76 T, and the plasma mass density is a fraction 1.7e-25 of the Aldred Limit density, settling by arithmetic that gravitational shear ceilings cannot bear on a device of this class. Every figure in the study is a computed result of the stated model and nothing was built or tested: the study is SIMULATED, NOT MEASURED, and its limits are stated as plainly as its performance.
