Diagnostic Port Plug

A shielded plug carrying instruments to the plasma edge.

Components & HardwareUpdated 2026-08-11
Role
Diagnostic access

Diagnostic port plugs mount instruments — cameras, spectrometers, probes — at vessel penetrations while maintaining shielding and vacuum. They integrate many diagnostics into a maintainable unit.

Common questions

What is a diagnostic port plug?

An instrumented plug that fills a vessel port, carrying diagnostic sensors while maintaining vacuum and neutron shielding. It packages measurement hardware into the machine's access openings.

Why integrate diagnostics into a shielded plug?

Because every opening is a gap in the shield. Building diagnostics into a shielding plug lets the machine see inside without compromising magnet protection or vacuum integrity.
