| 20110031866 | PLASMA RADIATION SOURCE, METHOD OF FORMING PLASMA RADIATION, APPARATUS FOR PROJECTING A PATTERN FROM A PATTERNING DEVICE ONTO A SUBSTRATE AND DEVICE MANUFACTURING METHOD - A patterned beam of radiation is projected onto a substrate. A reflective optical element is used to help form the radiation beam from radiation emitted from a plasma region of a plasma source. In the plasma source, a plasma current is generated in the plasma region. To reduce damage to the reflective optical element, a magnetic field is applied in the plasma region with at least a component directed along a direction of the plasma current. This axial magnetic field helps limit the collapse of the Z-pinch region of the plasma. By limiting the collapse, the number of fast ions emitted may be reduced. | 02-10-2011 |

| 20090153010 | BI-DIRECTIONAL DISPENSER CATHODE - A multi-directional dispenser cathode has a cathode body that supports a plurality of electron emitters which spanning open portions of the cathode body. Each electron emitter has an inward facing surface and an outward facing surface wherein the inward facing surfaces and an interior wall of the body define an interior volume that contains a heater. To selectively accelerate emitted electrons, an electrically distinct biasing electrode is in spaced relationship to the outward facing surface of each electron emitter and coupled to a biasing power supply effective to provide an intermittent positive voltage potential to the biasing electrode. The distinct biasing electrodes are provided with a positive voltage potential at different times thereby causing an intermittent burst of electrons. Among the applications for intermittent bursts of accelerated electrons are to generate radiation from a particle accelerator. | 06-18-2009 |
| 20100109503 | METHOD AND APPARATUS FOR POSITIONING A CERAMIC INDUCTION DISCHARGE BODY RELATIVE TO AN INDUCTION COIL - An electrodeless or induction ceramic HID lamp includes a ceramic arc body having a generally spheroidal portion enclosing a discharge chamber and an induction coil received around a perimeter portion of the spheroidal portion. At least one leg extends from the spheroidal portion of the arc body. A mounting structure connects the arc body to the surrounding lamp assembly. In one arrangement, a mounting tube is received over at least a portion of the leg, and may further include a light transmissive shroud that also abuts with the induction coil to precisely locate the arc body relative to the coil. In another arrangement, first and second mounting members extend from spaced locations of the arc body, either as pins or legs extending from the spheroidal portion, or radially extending legs from an equatorial portion of the arc body. In still another arrangement, a ceramic mounting member extends from the arc body and includes a thin peripheral rim having spaced ridges to engage spaced locations of the induction coil. | 05-06-2010 |
| 20100109504 | STARTING COIL FOR INDUCTION LIGHTING - Life of a starting conductor or coil in an induction lamp is significantly improved with the present disclosure. A mechanical support supports the starting coil adjacent the arc body of the lamp and has features that allow the starting coil to mount thereon. The mechanical support may be made of a high temperature material such as glass, quartz, or ceramic so that light from the lamp is not blocked. In another embodiment, the starting conductor is protected from oxidation by fully encasing the starting conductor within the high temperature material. In still another embodiment, a thin coating of a high temperature material that may or may not be light transmissive could be used as an alternative manner of support. | 05-06-2010 |
