250496100 | With container for radioactive source and radiation directing or selectable shielding | 6 |
20080224072 | Apparatus for and Method of Preparing a Small Amout of a Radioactive Substance Combination - The invention relates to an apparatus for preparing a small amount of a radioactive substance combination, including a one-part body, a mixing device integrated in the body and adapted to receive a small amount of chemical substances, and at least one receptacle integrated in the body and connected to the mixing device and adapted to hold a small amount of a chemical substance. | 09-18-2008 |
20090065712 | Dual neutron-gamma ray source - A dual neutron-gamma ray source comprises a compact neutron generator, a shield, a collimator, and an internal gamma target. The shield surrounds the compact neutron generator. The collimator traverses the shield from the compact neutron generator to a collimator port. The internal gamma target is positioned within the collimator to generate gamma rays from the neutrons. | 03-12-2009 |
20090065713 | Variable-ratio neutron-gamma ray source - A variable-ratio neutron-gamma ray source comprises a neutron generator, a shield, a collimator, and an external gamma target. The neutron generator generates neutrons and the shield reduces external radiation exposure. The collimator collimates the neutrons into a neutron beam that traverses the shield. The external gamma target generates a dual neutron-gamma ray beam from the neutron beam, wherein the dual neutron-gamma ray beam has a variable neutron-gamma ratio as a function of a thickness of the external gamma target. | 03-12-2009 |
20100019173 | Extreme ultraviolet light source apparatus and nozzle protection device - A nozzle protection device capable of protecting a target nozzle from heat of plasma without disturbing formation of a stable flow of a target material in an LPP type EUV light source apparatus. This nozzle protection device includes a cooling unit which is formed with an opening for passing the target material therethrough, and which is formed with a flow path for circulating a cooling medium inside, and an actuator which changes a position or a shape of the cooling unit between a first state of evacuating the cooling unit from a trajectory of the target material and a second state of blocking heat radiation from the plasma to the nozzle by the cooling unit while securing a path of the target material in the cooling unit. | 01-28-2010 |
20130082196 | COMPACT MODULAR PARTICLE FACILITY HAVING LAYERED BARRIERS - A layered barrier for a compact particle facility is provided; the layered barrier includes a first layer formed from first shielding elements and a second layer formed from second shielding elements. The first and second shielding elements are modular and have different shielding characteristics from one another. | 04-04-2013 |
20160064111 | ELECTRON BEAM IRRADIATION APPARATUS - An electron bears irradiation apparatus that emits am electron beam into a container, the electron beam irradiation apparatus including a vacuum housing constituting a vacuum chamber; an electron generator provided in the vacuum housing; a cylindrical nozzle member that is extended from the vacuum housing so as to be inserted into the container and has exit windows on the distal end of the nozzle member, the exit windows being provided for emission of an electron beard generated by the electron generator into the container; and a magnetic shield member for the vacuum chamber and a magnetic shield member for the nozzle member, the magnetic shield members being respectively provided for the vacuum housing and the nozzle member so as to block variable magnetism generated around an electron beam, trajectory extended from the electron generator to the exit windows. | 03-03-2016 |
