AI Technical Summary
Technical Problem
Current small animal proton therapy systems are unsuitable for preclinical studies due to high energy and large spot sizes, and existing solutions like energy degraders and beam collimators produce secondary radiation and lack flexibility.
Method used
A transportable beamline system for small animal proton therapy that includes an energy degrader, collimator, and focusing assembly with quadrupole magnets, mounted on a common base structure for precise alignment, allowing rapid installation at higher-energy proton sources.
Benefits of technology
Enables flexible and precise ion beam irradiation for small animals with minimal secondary radiation, suitable for various ion types and energies, and facilitates easy installation and alignment at different facilities.

Abstract
Disclosed herein is a transportable beamline (100, 200) for ion beam irradiation, in particular small animal ion beam irradiation, and a method (700) of aligning a transportable beamline. The beamline (100, 200) is configured to receive an ion beam (102), in particular a proton beam, from an ion beam source and to guide the ion beam (102) along a beam path (104) to a target point (106) that is to be irradiated. The beamline (100, 200) comprises: an energy degrader (108, 500) for decelerating ions in the ion beam (102); a collimator (110, 400) for collimating the ion beam (102); a focusing assembly (112) for focusing the ion beam (102), the focusing assembly (112) being arranged downstream of the energy degrader (108, 500) and the collimator (110, 400) along the beam path (104) for the ion beam (102) and comprising two or more quadrupole magnets (112A-C) arranged along the beam path (104); and a common base structure (114) to which at least the collimator (110, 400) and the focusing assembly (112) are mounted, the common base structure (114) being configured to preserve relative alignment between the collimator (110, 400) and the two or more quadrupole magnets (112A-C) during transport of the beamline (100, 200), wherein some or all of said two or more quadrupole magnets (112A-C) are removably mounted to the common base structure (114) via a respective kinematic mount (116, 300).
