Abstract: A flat solar chimney in accordance with the invention reduces a building's cooling load by dissipating the solar energy outside the building. What Applicants have done is construct an outer wall having an inner air space before the building structure. The solar light is absorbed by the outside layer which includes a porous metal layer. The heated high surface area foam metal creates a convective air flow in the channel that extends vertically with openings at the bottom and top. This flow dissipates the absorbed heat and is totally external to the building's interior. In a further embodiment of the invention, a plurality of rectangular slats either horizontally or vertically disposed act as venetian style blinds. The dynamic blinds allow visual function or the solar chimney as per need.

Abstract: An intensity modulator for controlling the intensity of ions, such as protons, controllably block a portion of sub-areas of an area beam to control the average intensity within that sub-area. A fan beam is then created by a focusing process that reforms the area beam while blurring intensity variations in each sub-area to a corresponding beamlet in the fan beam of uniform intensity.

Abstract: The x-ray system with a superconducting anode includes an anode of x-ray machine made from a material capable of superconductivity, which is then cooled to be in superconducting state while being bombarded by an electron beam to generate x-rays. If a non-superconducting heat island is formed, then a magnetic field is used to penetrate this region and spread the heat in the form of hot electrons over the target material.

Abstract: A system for modulating a fan beam for radiation treatment employs shutters that may move rapidly into and out of different beamlets of a fan beam, the shutters having a systematic weighting so that a limited number of shutters may obtain a far greater number of regularly spaced energy reductions.

Abstract: A modulator for radiation therapy provides modulation of an area beam to decrease treatment time. Separate channels passing modulated “beamlets” are possible by spacing the channels such that spreading of the beams and multiple angles of treatment eliminate cold spots. The space between the channels allows well-defined channel walls and space for modulator mechanisms.

Abstract: A phantom for heavy ion radiation therapy provides characterization of an ion beam that may enter but not exit from the phantom. The phantom may include multiple materials and multiple spatially dispersed ion detectors to obtain signals that may be fit to known beam curves to accurately characterize the location and other parameters of Bragg peak of a given ion beam within a patient.
