In a complex, multi-processor software controlled system, such as proton beam therapy system (PBTS), it may be important to provide treatment configurable parameters that are easily modified by an authorized user to prepare the software controlled systems for various modes of operation. This particular invention relates to a configuration management system for the PBTS that utilizes a database to maintain data and configuration parameters and also to generate and distribute system control files that can be used by the PBTS for treatment delivery. The use of system control files reduces the adverse effects of single point failures in the database by allowing the PBTS to function independently from the database. The PBTS accesses the data, parameter, and control settings from the database through the system control files, which insures that the data and configuration parameters are accessible when and if single point failures occur with respect to the database. |

Interposing a programmable path length of one or more materials into a particle beam modulates scattering angle and beam range in a predetermined manner to create a predetermined spread out Bragg peak at a predetermined range. Materials can be “low Z” and “high Z” materials that include fluids. A charged particle beam scatterer/range modulator can comprise a fluid reservoir having opposing walls in a particle beam path and a drive to adjust the distance between the walls of the fluid reservoir under control by a programmable controller. A “high Z” and, independently, a “low Z” reservoir, arranged in series, can be used. When used for radiation treatment, the beam can be monitored by measuring beam intensity, and the programmable controller can adjust the distance between the opposing walls of the “high Z” reservoir and, independently, the distance between the opposing walls of the “low Z” reservoir according to a predetermined relationship to integral beam intensity. Beam scattering and modulation can be done continuously and dynamically during a treatment in order to deposit dose in a target volume in a predetermined three dimensional distribution. |

A tunable LC circuit is used to trigger an electron discharge from an accelerator device, such as a Betatron. The circuit includes a coil as a first inductor having a first inductance electrically coupled in series with a capacitor. A second inductor having a variable inductance is electrically coupled, either in series or parallel, to the first inductor. The time to capacitor discharge is governed by: τLC=√{square root over ((L+LTUNE)C)}. Adjusting the inductance of the variable inductor (LTUNE) facilitates continuous adjustment of the discharge time. This is particularly useful when the LC values change in response to external stimuli, such as borehole temperature when a Betatron is used to log borehole features. |

A foil is formed on a given substrate, then, peeled off of the substrate and floated on the water surface charged in a tank. The surface level of the water is decreased to contact the foil to a folding plate of a jug substrate and thus, fold the foil at the folding plate in two. The two surfaces of the foil opposing each other are laminated along a foil forming-supporting plate within a laminating region. The thus laminated foil is dried and annealed except the area in the vicinity of the foil forming-supporting plate, and then, cut along the folding plate, a foil acceptor and a supporting plate, to provide a stripping foil which can be supported by itself. |

A particle accelerator system, including apparatuses and methods, that is configurable through repositioning of shorting devices therein to operate at different charged particle beam currents while maintaining optimum transfer of electromagnetic power from electromagnetic waves to one or more accelerating sections thereof, and reducing or eliminating reflections of electromagnetic waves. The particle accelerator system includes at least two accelerating sections and an electromagnetic drive subsystem with portions of the electromagnetic drive subsystem being interposed physically between the accelerating sections, thereby making the particle accelerator system compact. The electromagnetic drive subsystem includes, among other components, a 3 dB waveguide hybrid junction having a coupling window in a narrow wall thereof which is shared by the junction's rectangular-shaped waveguides. By virtue of the coupling window being positioned in a narrow wall rather than a wide wall, the maximal power of the 3 dB waveguide hybrid junction is increased significantly. |

The CMMBA also provides the ability to tailor the system momentum compaction spectrum as desired for specific applications. The CMMBA enables magnetostatic management of the longitudinal phase space in Energy Recovery Linacs (ERLs) thereby alleviating the need for harmonic linearization of the RF waveform. |
