The present disclosure provides a display panel including at least one pixel region located in a display area, each pixel region includes: at least one first pixel including at least one display light-emitting sub-pixel and at least one near-infrared light-emitting sub-pixel, wherein the near-infrared light-emitting sub-pixel is configured to emit near-infrared light; and at least one second pixel including at least one display light-emitting sub-pixel and at least one near-infrared receiving sub-pixel, wherein the near-infrared receiving sub-pixel is configured to receive near-infrared light reflected from an external object and generate a measurement signal responsive to the external object. The present disclosure also provides a display device including the display panel, and a method for determining the position of an external object by the display device.

The invention comprises a laying, semi-vertical, or seated patient positioning, alignment, and/or control method and apparatus used in conjunction with multi-axis charged particle or proton beam radiation therapy of cancerous tumors. Patient positioning constraints are used to maintain the patient in a treatment position, including one or more of: a seat support, a back support, a head support, an arm support, a knee support, and a foot support. One or more of the positioning constraints are movable and/or under computer control for rapid positioning and/or immobilization of the patient. The system optionally uses an X-ray beam that lies in substantially the same path as a proton beam path of a particle beam cancer therapy system. The generated image is usable for: fine tuning body alignment relative to the proton beam path, to control the proton beam path to accurately and precisely target the tumor, and/or in system verification and validation.

An ion source comprising a chamber and an electron collector is described. In one configuration, the chamber comprises a sample inlet and an ion outlet. The chamber may also include an electron inlet configured to receive electrons from an electron source. The electron collector can be arranged in opposition to the electron inlet. The chamber can be configured to direct an electron beam from the electron source along a path with the chamber transverse to a path between the gas inlet and the ion outlet. The chamber may comprise an ion guide that includes a guide axis offset from an axis of the ion outlet.

Certain configurations of ionization sources are described. In some examples, an ionization source comprises an ionization block, an electron source, an electron collector, an ion repeller and at least one electrode configured to provide an electric field when a voltage is provided to the at least one electrode. Systems and methods using the ionization source are also described.

The present disclosure describes an ion implantation system that includes a bushing designed to reduce the accumulation of IMP by-produces on the bushing's inner surfaces. The ion implantation system can include a chamber, an ion source configured to generate an ion beam, and a bushing coupling the ion source and the chamber. The bushing can include (i) a tubular body having an inner surface, a first end, and a second end and (ii) multiple angled trenches disposed within the inner surface of the tubular body, where each of the multiple angled trenches extends towards the second end of the tubular body.

An apparatus for separating and analyzing ions includes a detector, a planar ion drift tube coupled to the detector and having a width, and a planar ion source. The planar ion source is coupled to the ion drift tube on an end of the ion drift tube opposite the detector and has a span greater than or equal to the width of the ion drift tube to ionize an analyte gas and fragment the analyte gas ions prior to admittance to the ion drift tube. Chemical detectors and methods of chemical detection are also described.

A system that utilizes a component that controls thermal gradients and the flow of thermal energy by variation in density is disclosed. Methods of fabricating the component are also disclosed. The component is manufactured using additive manufacturing. In this way, the density of different regions of the component can be customized as desired. For example, a lattice pattern may be created in the interior of a region of the component to reduce the amount of material used. This reduces weight and also decreases the thermal conduction of that region. By using low density regions and high density regions, the flow of thermal energy can be controlled to accommodate the design constraints.

An ion source apparatus which generates dopant species in a manner enabling low vapor pressure dopant source materials to be employed. The ion source apparatus (10), comprising: an ion source chamber (12); and a consumable structure in or associated with the ion source chamber (12), said consumable structure comprising a solid dopant source material susceptible to reaction with a reactive gas for release of dopant in gaseous form to the ion source chamber. For example, the consumable structure is a dopant gas feed line (14) comprising a pipe or conduit having an interior layer formed of a solid dopant source material.
