From the design of the first Cyclone 30 cyclotron to the global recognition of proton therapy, the narrative follows a path marked by breakthroughs, crises overcome, and strategic rebounds. It explores the technical, financial, and human challenges faced by an academic start-up that grew into an international player, balancing boldness with rigour, applied research with industrial performance. But IBA is more than a technological pioneer: it is a corporate citizen committed to advancing the common good. Its model is based on balancing the interests of stakeholders—patients, employees, customers, shareholders, communities, and the environment. Its mission — “to protect, enhance, and save lives” — is made tangible through the thousands of patients treated, the hundreds of accelerators installed worldwide, and a culture deeply rooted in trust, transparency, and long-term vision. Beyond machines and markets, IBA is a mindset: an attentive and daring organisation, faithful to its roots yet firmly focused on the future.
