The ProTom Radiance 330 proton radiotherapy system provides the most advanced proton delivery capability to date. It supports true three-dimensional beam scanning with dynamic energy and intensity modulation. Most of the protons extracted from the synchrotron are used to treat the patient, which results in minimal neutron background in the treatment room. The patient dose rate depends upon the number of protons injected and the acceleration cycle time. Therefore, one can boost the dose rate by increasing the beam intensity at injection. Improvements to the existing tandem accelerator injector are already underway. However, an alternative way to attain higher intensity beam is to use an RFQ linac as an injector. To this end, a novel 1.6 MeV RFQ linac has been designed to specifically satisfy the small energy acceptance limits of the synchrotron. Simulations of the beam line optics and injection matching to the synchrotron have been performed using the computer codes PARMILA and TRACE-3D to determine if an ...
