Description

LOWER PROJECT COST
The synchrotron changes energies electronically, by varying the number of times protons are accelerated around the ring. This is a very clean process; operators turn the machine off and walk into the vault a minute later since there is no residual radioactivity. Cyclotrons utilize a beam degrader and energy selection system to change energies; these mechanisms generate neutrons inside the vault, requiring thicker walls for radiation shielding. Radiance 330 results in lower costs for radiation shielding.

COMPACT SIZE
The smaller size (and weight) of the equipment reduces manufacturing, transportation, installation, rigging, and facility costs. The accelerator vault interior requires only 20’ x 30’ of space for the 16’ diameter synchrotron. The Lunder Building at MGH features a Radiance 330 gantry-based proton therapy suite inside the space of two former linac vaults. The reduced scale and adaptable equipment configurations* will enable many hospitals to add proton therapy as an extension of the existing cancer center, obviating the need to purchase more land for a separate facility.

MULTIPLE TREATMENT ROOMS
The compact and advanced design of the Radiance 330 synchrotron accelerator supports single and multiple treatment room facilities. The beam transport system is a beam-line and beam-switchyard behind-the-scenes that guides the proton beam from the synchrotron to the treatment room, and is extensible to as many as three treatment rooms. An affordable facility can be designed with future expansion in mind for those who prefer to add an additional treatment room at a later time.
