Abstract: Concentrating process and device for an electron beam.. Is intended to be used in combination with an electron beam welding apparatus in which it is important that the beam will be concentrated and regulated in a precise manner. A plate is arranged, which comprises a slit, at the point where it is desired to concentrate the beam. The beam is oscillated through the plate so that the electrons pass through the slit and pass into a collecting cup; the potential developed in this cup is measured and the beam is then concentrated so that the potential developed in this cup is measured and the beam is then concentrated so that the potential is at a maximum value. The device is intended to be used in combination with a welding apparatus and an oscillograph for operating the process. It comprises in combination a heat dissipater, a plate supported by this dissipator and comprising a slit, and a collecting cup, supported by the heat dissipater but insulated from the latter by a ceramic material. The cup is arranged so that the electrons can pass through the slit and pass into the cup.

Abstract: 826,071. Spark apparatus. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. June 19, 1958 [June 20, 1957], No. 19515/57. Class 39(1). [Also in Group XL(c)] In a high voltage pulse generator, Fig. I, (see Group XL(c)) in which spark gaps SG1, SG11, SG12 control the discharge of capacitors to produce heavy current pulses in a gas in a discharge tube 5, the spark gaps have the form shown in Fig. 2. Each consist of two circular main electrodes 1, 2 having a main gap 4 between them. The electrode 2 has a central hole into which projects an irradiating electrode 3 which does not quite extend to the surface of electrode 2. The electrodes may operate in air or be sealed in an evacuated or gas filled tube, an auxiliary discharge being produced initially between electrodes 2, 3.

Abstract: A mass spectrometer ion reaction device, useful for performing ion-ion reactions (eg. ETD, PTR) is described. The device includes a plurality of non-linear rods, that form a pair of quadrupole rod sets. The device includes an axial passageway, that allows injections of ions of both polarities into the device, and a three dimensional trapping region. Anions and cations that are injected into the device are spatially separated into different trapping regions by a DC dipole electric field generated by a DC voltage source. The device also includes a plurality of lenses to confine, transmit or receive ions in/from the device.

Abstract: A radiation attenuation corridor couples a radiation therapy room and a control room. The radiation attenuation corridor is made of a material that substantially absorbs ionizing radiation and substantially blocks the transmission of the ionizing radiation. Specific wall portions at the entrance of the corridor are covered with borated polyethylene (BPE). Specific wall portions diverge from an axis defined by the corridor by from about 10 degrees to about 45 degrees. The corridor thus leads out of the room and angles laterally across the wall of the therapy room, before angling again and opening to a safe room. The added angles in the radiation corridor increase the distance of radiation travel, and make the path more indirect, thereby increasing the contact of the radiation emissions with the radiation shielding and further attenuating the radiation.
