“…The current dedicated PBT systems, as well as the limited converted physics facilities were all constructed with large footprint accelerators that are expensive to build and maintain. The Compact Particle Acceleration Corporation (CPAC) is leveraging advances in high gradient insulators (HGI) and the dielectric wall accelerator (DWA) to develop a compact proton accelerator for radiotherapy and radiosurgery that will be only a fraction of the footprint of current systems, which could be located in a single treatment room with significantly less infrastructure investment [1]. In addition, this architecture can provide real-time energy modulation to match the proton beam's Bragg peak to target tumours at different depths.…”

“…In this case switching was provided by turn-ON photoconductive switches [2]. A subsequent significant advance in the coreless DW structure was the introduction of a high gradient insulator that also served as vacuum envelope encompassing the beam [3]. At that time, some investigators believed that integration of a cast solid dielectric in the pulse forming lines with a high gradient vacuum interface and SiC photoconductive switches might achieve gradients approaching 250 MeV/m.…”

A novel short-pulse concept (SLIM) suited to a new generation of a high gradient induction particle accelerators is described herein. It applies advanced solid state semiconductor technology and modern microfabrication techniques to a coreless induction method of charged particle acceleration first proven on a macro scale in the 1960's. Because this approach avoids use of magnetic materials there is the prospect of such an accelerator working efficiently with accelerating pulses in the nanosecond range and, potentially, at megahertz pulse rates. The principal accelerator section is envisioned as a stack of coreless induction cells, the only active element within each being a single, extremely fast (subnanosecond) solid state opening switch: a Drift Step Recovery Diode (DSRD). Each coreless induction cell incorporates an electromagnetic pulse compressor in which inductive energy developed within a transmission-line feed structure over a period of tens of nanoseconds is diverted to the acceleration of the passing charge packet for a few nanoseconds by the abrupt opening of the DSRD switch. The duration of this accelerating output pulse -typically two-to-four nanoseconds -is precisely determined by a microfabricated pulse forming line connected to the cell.Because the accelerating pulse is only nanoseconds in duration, longitudinal accelerating gradients approaching 100 MeV per meter are believed to be achievable without inciting breakdown. Further benefits of this approach are that, (1) only a low voltage power supply is required to produce the high accelerating gradient, and, (2) since the DSRD switch is normally closed, voltage stress is limited to a few nanoseconds per period, hence the susceptibility to hostile environment conditions such as ionizing radiation, mismatch (e.g. in medical applications the peak beam current may be low), strong electromagnetic noise levels, etc is expected to be minimal. Finally, we observe the SLIM concept is not limited to linac applications; for instance, it could be employed to both accelerate the beam and to stabilize the superbunch mode of operation in circular track machines.
