Résumé

The Harvard Cyclotron produced its first beam on June 3, 1949 and continued to operate until 2003 - a record breaking 54 years. This uniquely long operating life for a high energy cyclotron was due to the importance and variety of its applications and to its relatively low cost for operations and maintenance. These low costs came from clever design features and from its dedicated staff.

The initial research with the Harvard Cyclotron was for nuclear and particle physics. It concentrated on using proton beams of up to 160 Mev to study the interactions of protons with target protons, deuterons, helium and other nuclei... The Harvard Cyclotron proved to be an excellent facility for training graduate students. 30 Harvard Ph.D. -theses, and as many from neighboring Universities and many physics papers were based on the Harvard Cyclotron.

While directing the design of the Harvard Cyclotron, Robert R. Wilson in 1946 wrote an important paper in which he pointed out that a high energy proton beam should be effective for cancer therapy since, near the end of its range, a proton beam produces a greater ionization density. By arranging for the cancer to be bombarded from different directions but with the ends of the ranges being at the cancer, the damage to the cancer would be maximized with minimum damage to the non-cancerous tissue...
