The present disclosure provides a self-contained system that contains a plurality of target cartridges, automatically inserts a selected target cartridge into position for irradiation, advances a foil to facilitate irradiation over the target chamber, replaces the foil for additional irradiation (if desired), serves as a dissolution cell for retrieval of the irradiated material, removes the used target cartridge and inserts a new cartridge for subsequent cycles of operation. Consequently, only the dissolved target material and dissolution medium are transferred between the target system and any post processing cells/labs. Accordingly, a system is disclosed for processing a target material without disturbance to irradiated material (thereby eliminating risk of impurities) and without requiring manual access/intervention (thereby eliminating risk of exposure).

A gantry-less particle therapy system is provided. Charged particles are extracted from an ion source and accelerated in a beam transport system having an annular portion extending in a first plane and that circumscribes a volume, an arcuate portion extending in a second plane, and a transition portion that connects the annular portion and the arcuate portion. The arcuate portion terminates at a beam nozzle extending radially inward from the annular portion to deliver an ion beam to a treatment area contained in the volume circumscribed by the annular portion.

A synchrocyclotron for extracting charged particles accelerated to an extraction energy includes a magnetic unit comprising N valley sectors and N hill sectors, and configured for creating z-component of a main magnetic characterized by a radial tune of the successive orbits. The synchrocyclotron includes a first instability coil unit and a second instability coil unit configured for creating a field bump of amplitude increasing radially. The amplitude of the field bump may be varied to reach the value of the offset amplitude at the average instability onset radius. The offset amplitude may be the minimal amplitude of the field bump at the average instability onset radius required for sufficiently offsetting the center of the orbit of average instability onset radius to generate a resonance instability to extract the beam of charged particle at the average instability onset radius.

A time-of-fight measurement system for measuring energy of a pulsed hadron beam, wherein each pulse of the beam is structured into a series of bunches of charged particles, said bunches being repeated according to a repetition rate of the order of magnitude of radiofrequency. The system comprises a first detector, a second detector and a third detector arranged along a beam path, each of the detectors being configured to detect the passage of a bunch of charged particles and provide an output signal dependent on phase of the detected bunch, wherein the second detector is spaced apart from the first detector by a first distance and wherein the third detector is spaced apart from the second detector by a second distance, wherein the first distance is set out in such a way as that time of flight of the bunch from the first detector to the second detector is approximately equal to, or lower than a repetition period of the bunches, and wherein the second distance is set out in such a way as that time of flight of the bunch from the second detector to the third detector is greater than a multiple of the repetition period of the bunches, and a processing unit configured to a) calculate phase shifts between the output signals of the detectors, and b) calculate energy of the pulse based on the calculated phase shifts.

One of the obstacles to the widespread use of proton therapy is the availability of affordable and compact proton sources and accelerators. The use of linear accelerators allow the construction of such a compact source which may be installed in existing medical facilities. However, instability occurs after accelerating units are turned on or off. A proton linear accelerator system configured to provide RF energy during the off-time of the proton beam operating cycle may be used for increasing or maintaining the temperature of cavities. A method of operating a proton beam is also provided which is suitable for irradiating tissue. These may provide an improved settling time.

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of pulses having different energy levels or different doses.

To provide a functional membrane for ion beam transmission capable of enhancing ion beam transmittance and improving beam emittance. A functional membrane for ion beam transmission according to the present invention is used in a beam line device through which an ion beam traveling in one direction passes and has a channel.
