We were able to successfully measure with PEPITES our first profile of a therapeutic beam of carbon ions delivered by the CNAO (Pavia, Italy) !
The CNAO (Centro Nazionale di Adroterapia Oncologica), located in Pavia, Italy, delivers therapeutic proton and carbon beams. We were able to test our ultrathin PEPITES beam monitor there for 2 nights on November 19 and 20, 2023. The profiles were successfully measured for proton and carbon ion beams over a wide energy range (from 62 MeV to 227 MeV for protons and from 115 MeV/u to 395 MeV/u for carbon ions)
Plots of first carbon ion beam recorded by PEPITES. On the right, current measurements with horizontal et vertical strips. The reconstructed spot if shown on the lower left corner.
The detector was located in its vacuum chamber, equipped with its dedicated electronics developed at the CEA
PEPITES vacuum chamber on the CNAO experimental beam line.
