The particle beam characteristics can be compatible with FLASH radiation therapy. Resolution control of the particle beam generation can enable dose delivery at an intra-pulse level and micro-bunch level. The micro-bunch can include individual bunches per each 3 GHz RF cycle within the 5 to 15 μsec pulse-width. The FLASH radiation therapy dose delivery can have a bunch level resolution of approximately 4.4×10{circumflex over ( )}-6 cGy/bunch.

A method for treating a disease, disorder, or condition in a subject in need thereof, by administering either or both of (i) at least one photoactivatable pharmaceutical agent, or (ii) a first plurality of energy-emitting particles, into the subject in a region of the disease, disorder, or condition, whereby the administering is performed through inhalation; and applying an applied electromagnetic energy to the subject, wherein the applied electromagnetic energy directly or indirectly activates the at least one photoactivatable pharmaceutical agent, when present, and wherein when the first plurality of energy-emitting particles is present, the first plurality of energy-emitting particles absorbs the applied energy and emits an emitted electromagnetic energy, wherein the emitted electromagnetic energy interacts directly with the region of the disease, disorder, or condition or activates the at least one photoactivatable pharmaceutical agent.

A proton linear accelerator system that irradiates tissue with improved beam energy control, providing RF energy from a first RF energy source during on-time of the proton beam operating cycle for changing the energy of the proton beam, and providing RF energy from a second distinct RF energy source during off-time of the proton beam operating cycle for increasing or maintaining the temperature of the cavity. Each RF source is operated independently, allowing higher RF pulse rates to reach the cavity, supporting a smaller time between proton beam energy pulses. In addition, the peak power requirements for the second RF energy source may, in general, be less than for the second RF energy source, allowing a less costly type to be used for the second source. The use of a first and second RF source may reduce the cavity settling time from minutes to less than 10 seconds.
