An open-hardware radiotherapy machine built for unreliable power and dust

Design a radiotherapy machine from scratch for hospitals with patchy electricity, heat and few engineers, and publish the design so several companies can build it cheaply.

Commercial linear accelerators are built for well-staffed Western hospitals; in sub-Saharan Africa they sit idle for long stretches because of power failures, heat, and the cost of a service call. A consortium (the CERN/STFC/ICEC 'Project STELLA' work is a precedent) would specify a ruggedised, modular, remotely diagnosable machine with battery-buffered power, sealed electronics, swappable modules that a local technician can replace, and an open interface specification. The design and test data would be published so multiple manufacturers can bid; the buyer pays for uptime, not for the box.

Hypothesis
A purpose-designed machine will achieve more than 90% scheduled uptime in district hospitals in sub-Saharan Africa, against a historical figure well below that for conventional linacs in the same settings, at a total ten-year cost of ownership at least 40% lower.
Rationale
Every other capital good used in low-resource health systems (solar vaccine refrigerators, oxygen concentrators, GeneXpert) was eventually redesigned for the environment rather than shipped as-is. Radiotherapy has never had that redesign, despite the IAEA DIRAC database showing dozens of countries with one or zero working machines.
What would test it
Fund a two-year design phase with a published requirements document, then a three-site field trial (one machine each in three countries) measuring uptime, mean time to repair, dose accuracy audits by the IAEA, and patients treated per month against a matched conventional linac.
