  • Publication number: 20230082224
    Abstract: An ion source capable of extracting a ribbon ion beam with improved uniformity is disclosed. One of the walls of the ion source has a protrusion on its interior surface facing the chamber. The protrusion creates a loss area that serves as a sink for free electrons and ions. This causes a reduction in plasma density near the protrusion, and may improve the uniformity of the ribbon ion beam that is extracted from the ion source by modifying the beam current near the protrusion. The shape of the protrusion may be modified to achieve the desired uniformity. The protrusion may also be utilized with a cylindrical ion source. In certain embodiments, the protrusion is created by a plurality of mechanically adjustable protrusion elements.

  • Publication number: 20230080083
    Abstract: An ion source having an extraction plate with a variable thickness is disclosed. The extraction plate has a protrusion on its interior or exterior surface proximate the extraction aperture. The protrusion increases the thickness of the extraction aperture in certain regions. This increases the loss area in those regions, which serves as a sink for ions and electrons. In this way, the plasma density is decreased more significantly in the regions where the extraction aperture has a greater thickness. The shape of the protrusion may be modified to achieve the desired plasma uniformity. Thus, it may be possible to create an extracted ion beam having a more uniform ion density. In some tests, the uniformity of the beam current along the width direction was improved by between 20% and 50%.

  • Patent number: 11542594
    Abstract: An advanced sputter target is disclosed. The advanced sputter target comprises two components, a porous carrier, and a metal material disposed within that porous carrier. The porous carrier is designed to be a high porosity, open cell structure such that molten material may flow through the carrier. The porous carrier also provides structural support for the metal material. The cell sizes of the porous carrier are dimensioned such that the capillary action and surface tension prohibits the metal material from spilling, dripping, or otherwise exiting the porous carrier. In some embodiments, the porous carrier is an open cell foam, a weave of strands or stacked meshes.

  • Publication number: 20220406554
    Abstract: A crucible that exploits the observation that molten metal tends to flow toward the hottest regions is disclosed. The crucible includes an interior in which dopant material may be disposed. The crucible has a pathway leading from the interior toward an aperture, wherein the temperature is continuously increasing along the pathway. The aperture may be disposed in or near the interior of the arc chamber of an ion source. The liquid metal flows along the pathway toward the arc chamber, where it is vaporized and then ionized. By controlling the flow rate of the pathway, spillage may be reduced. In another embodiment, an inverted crucible is disclosed. The inverted crucible comprises a closed end in communication with the interior of the ion source, so that the closed end is the hottest region of the crucible. An opening is disposed on a different wall to allow vapor to exit the crucible.

  • Publication number: 20220359147
    Abstract: A system and method for extending the life of a cathode and repeller in an IHC ion source is disclosed. The system monitors the health of the cathode by operating using a known set of parameters and measuring the bias power used to generate the desired extracted beam current or the desired current from the arc voltage power supply. Based on the measured bias power, the system may determine whether the cathode is becoming too thin, and may take a corrective action. This corrective action may be to alert the operator; to operate the IHC ion source using a predetermined set of parameters; or to change the dilution used within the IHC source. By performing these actions, the life of the cathode may be more than doubled.

  • Patent number: 11404254
    Abstract: An ion source with an insertable target holder for holding a solid dopant material is disclosed. The insertable target holder includes a pocket or cavity into which the solid dopant material is disposed. When the solid dopant material melts, it remains contained within the pocket, thus not damaging or degrading the arc chamber. Additionally, the target holder can be moved from one or more positions where the pocket is at least partially in the arc chamber to one or more positions where the pocket is entirely outside the arc chamber. In certain embodiments, a sleeve may be used to cover at least a portion of the open top of the pocket.

  • Patent number: 11251010
    Abstract: A system for extending the life of a repeller in an IHC ion source is disclosed. The system includes an IHC ion source wherein the back surface of the repeller has been shaped to reduce the possibility of electrical shorts. The separation distance between the back surface of the repeller and the chamber wall behind the repeller is increased along its outer edge, as compared to the separation distance near the center of the repeller. This separation distance reduces the possibility that deposited material will flake and short the repeller to the chamber wall. Further, in certain embodiments, the separation distance between the back surface of the repeller and the chamber wall near the center of the repeller is unchanged, so as to minimize the flow of gas that exits from the chamber. The back surface of the repeller may be tapered, stepped or arced to achieve these criteria.

  • Patent number: 11160454
    Abstract: Described here are systems and methods for visualizing thermal ablation lesions by imaging specific chemical compounds that are created during thermal ablation procedures, such as cardiac ablation procedures. When a cardiac ablation procedure is performed, a central area of coagulative necrosis is created at the treatment site. This necrotic region is surrounded by layers of tissues with ultra-structural and electrophysiological changes. Two particular changes include the denaturation of proteins and the formation of ferric iron containing chemical compounds, such as methemoglobin and metmyoglobin. The formation of and distribution of such chemical compounds can be imaged with the appropriate systems and methods. Accordingly, these chemical compounds can be utilized as biomarkers that indicate the presence and physical characteristics of thermal ablation lesions. Imaging can be performed using magnetic resonance imaging, optical imaging, or photoacoustic imaging, as examples.
