This would be good news for many cancer patients if it can become a reality.
Particle physics pushing cancer treatment boundaries

Researchers at Europe's science lab CERN, who regularly use particle physics to challenge our understanding of the universe, are also applying their craft to upend the limits to cancer treatment.

The physicists here are working with giant particle accelerators in search of ways to expand the reach of cancer radiation therapy, and take on hard-to-reach tumours that would otherwise have been fatal.

... One challenge is making the powerful accelerator compact enough to fit inside a hospital.

At CERN, a large gallery has been dedicated to housing the CLEAR accelerator, which requires 20 metres to push the electrons up to the required energy level—and another 20 metres to condition, measure and deliver the beam.

But Corsini insisted that CERN had the know-how to "accelerate in a much more compact space".

The prototype being designed with CHUV will aim to do the same job with a machine that is 10 metres overall.

This "compact" solution, Corsini said, "reduces the cost, reduces power consumption and variability, and you can easily put it into a hospital without having to build a whole building."
