Ultra-high dose rate · ≥40 Gy/s

Radiation delivered faster than harm.

A Norwegian hub connecting research groups, treatment centres, and medical-device companies working on FLASH radiotherapy — so people who build beams, plan treatments, and study the biology can find each other and collaborate where their strengths complement.

The physics

Same dose. A thousand times faster.

FLASH radiotherapy delivers a full treatment dose in a fraction of a second, at dose rates orders of magnitude above conventional beams. In preclinical work this ultra-fast delivery appears to spare healthy tissue while still controlling the tumour — the effect the field is now racing to understand and translate to patients.

Conventional radiotherapy
~0.03Gy/s

Dose spread over minutes across many fractions. Healthy tissue in the beam path absorbs damage along the way.

FLASH radiotherapy
≥40Gy/s

The same physical dose delivered in under a second. The observed normal-tissue sparing is what makes FLASH worth building around.

// Delivered experimentally with electrons, protons, and photons. With particle beams the dose concentrates at the Bragg peak — deep in the target, sparing the entrance — which is the interaction you are steering in the beam above. Mechanisms remain under active investigation.

The network

FLASH needs beams, biology, and patients in the same room.

Each group holds a piece. We connect Norwegian and international actors so complementary strengths meet — and so a small alliance punches above its weight in a field moving this fast.

01 / Exchange

Move people and know-how

Research visits, shared measurement campaigns, and joint training between accelerator physicists, medical physicists, radiobiologists, and clinicians.

02 / Complement

Match strengths, not duplicate them

A dosimetry lab, a proton centre, and a device maker each bring one piece. We help them assemble the whole.

03 / Translate

From bench to beam line to bedside

Coordinated proposals, shared protocols, and a route from preclinical evidence toward safe first-in-human FLASH delivery.
