Laser Acceleration of Proton Beams
A technique using high-intensity light pulses could advance research on cancer therapies.
For decades, oncologists have used direct irradiation by X-rays, electrons or proton beams to zap tumors in cancer patients. But conventional radiotherapy can harm surrounding, healthy tissue as well. And, while research has lately suggested that very fast, pulsed delivery of radiation doses could excel at killing tumors while sparing healthy tissues, limited research infrastructure has held back progress.
