01

Candidate A: the refuge

Place a candidate coil arrangement around a limited crew refuge and compare it with a passive refuge of equal total installed mass. Examine all access directions, surrounding material and realistic occupancy. Concentrating protection is a study option, not a selected flight design.

02

Candidate B: one habitat module

Evaluate an external coil arrangement with a deliberately low-field occupied region, informed by published toroidal and Halbach-array concepts. Keep a conventional pressure vessel, debris protection and emergency systems. Coil geometry, current, standoff, conductor and temperature remain unresolved design variables.

03

Candidate C: the station envelope

Use a larger external array as a comparison case. Larger structures introduce launch packaging, deployment, flexibility, thermal and visiting-vehicle constraints. The first model should be allowed to reject this option; scale alone does not establish efficiency.

04

High-temperature does not mean room temperature

Superconducting operation still needs a controlled cold environment and current margin. Sum radiation, support conduction, current leads, joints and transient heat loads at the actual cold stage. Convert cold-stage load into spacecraft electrical demand using a specified cooler performance map. The nozzle’s heat-leak and coil-power figures cannot be scaled directly to this shield.

05

Stored energy must go somewhere

Use a structural model for magnetic loads and a fault model for quench detection, protection and energy discharge. Check loss of cooling, sensor failure and interrupted deployment. Evaluate fields and induced currents at docking vehicles, electronics, payloads and crew locations. NASA’s MAARSS work identifies these as coupled engineering issues [1].
