Improvements in or relating to cathode ray tubes

... 277,347. M³ller Akt.-Ges., C. H. F., Assignees of Thaller, R.). Sept. 7, 1926, [Convention date]. Vacuum tubes. - In Lenard cathode-ray tubes in which the cathode rays from a highly emissive cathode pass out of the tube through their aluminium or other foils, the foils are cooled during normal operation of the tube by blowing a current of gas or liquid on to them. The foils are thus protected from damage due to the heat produced by the absorption of some of the electrons, so that the cathode emission and radiant energy may be increased. Discharge voltages of 250,000 volts with incandescent cathodes, also tubes constantly connected to a vacuum pump, are referred to. In a tube with a spiral incandescent cathode 2 and annular anode 3, the foil 4 is supported by a grid 5 and cooled by gas jets from nozzles 8 in an annular pipe 7.

Treating biomass

Method of making an electron beam window

A method of making an electron permeable window is provided which entails depositing a thin film of an inert, high strength material or compound having a low atomic number onto a substrate by chemical vapor deposition (CVD). Following that deposition, a window pattern and window support perimeter are photolithographically defined and the substrate is etched to leave the desired window structure. For a particular class of materials including SiC, BN, B 4 C, Si 3 N 4 , and Al 4 C 3 , films are provided which are exceedingly tough and pinhole free, and which exhibit nearly zero internal stress. Furthermore, due to their extreme strength, these materials allow fabrication of extremely thin windows. In addition, because of their low atomic number and density, they have excellent electron penetration characteristics at low beam voltages (15 to 30 kV), so that most conventional CRT deflection schemes can be used to direct the beam. Also, such films are remarkably resilient and chemically inert even when very thin and can easily withstand large pressure differences.

The known material polypropylene is not available in the desired thickness of the order of 1νm, and stretching of this material so as to reduce the thickness causes an inadmissible spread in thickness. The material polyethylene naphtalate (PEN) in accordance with the invention is available in the desired thickness and with a much smaller spread in thickness. Furthermore, the window material should exhibit suitable mechanical properties (such as strength, rigidity and tightness) which are not allowed to degrade significantly under the influence of continuously varying circumstances in respect of pressure, temperature and X-rays. In comparison with the known polyethylene terephtalate (PET), PEN in this respect has better properties which satisfy the mechanical requirements.

Output window for electron beam in isotope production

Изобретение относится к выводному окну для электронного пучка из линейного ускорителя для использования в процессе производства радиоизотопов. Выводное окно содержит цилиндрический канал, функционально соединяемый на одном конце с вакуумной камерой, предназначенной для прохождения через нее электронного пучка, а также куполообразную чашевидную головку на другом конце канала. Причем чашевидная головка содержит выпуклую часть, имеющую выступающую верхнюю часть, предназначенную для прохода через нее электронного пучка. Геометрия куполообразной чашевидной головки выбрана так, чтобы обеспечивать сопротивление напряжению от давления, создаваемого охлаждающей средой, циркулирующей вокруг выступающей верхней части, и вакуумом в цилиндрическом канале, и поддерживать объединенные тепловое напряжение и напряжение от давления ниже предела усталости материала, образующего выводное окно. Техническим результатом является возможность выводного окна для электронов выдерживать в ходе производства изотопов с использованием потока тормозного излучения высокие перепады давления с минимизацией усталостного разрушения из-за высоких динамических термически индуцированных напряжений, вызванных импульсным электронным пучком, 31 з.п. ф-лы, 2 ил.

Output window for electron beam in isotope production

FIELD: radioisotope production. SUBSTANCE: invention relates to an output window for an electron beam from a linear accelerator for use in the production of radioisotopes. The output window contains a cylindrical channel functionally connected at one end to a vacuum chamber designed for the passage of an electron beam through it, as well as a domed cup-shaped head at the other end of the channel. The cup-shaped head contains a convex part having a protruding upper part designed for the passage of an electron beam through it. The geometry of the domed cup-shaped head is chosen so that to provide resistance to tension from the pressure created by a cooling medium circulating around the protruding upper part and the vacuum in the cylindrical channel, and to maintain combined thermal tension and pressure tension below the fatigue limit of material forming the outlet window. EFFECT: possibility of the output window for electrons to withstand high pressure drops during the production of isotopes using a braking radiation flux with minimization of fatigue failure due to high dynamic thermally induced tensions caused by a pulsed electron beam. 32 cl, 2 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 762 668 C9 (51) МПК H05H 7/22 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) СКОРРЕКТИРОВАННОЕ ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ Примечание: библиография отражает состояние при переиздании (52) СПК H05H 7/22 (2021.05) (21)(22) Заявка: 2019126617, 26.01.2018 26.01.2018 (73) Патентообладатель(и): КАНЕЙДЬЕН ЛАЙТ СОРС ИНК.

Electron-beam irradiation method and device (alternatives)

FIELD: electronic engineering. SUBSTANCE: proposed method and device make use of triangular-wave generator that produces triangular-waveform current signal conveyed to scanning coil for electron beam displacement in first scanning direction Y and rectangular-wave generator that produces rectangular-waveform current pulse arriving at deflection coil for displacing electron beam in second scanning direction X perpendicular to first scanning direction Y. Triangular-waveform current signal produced by triangular-wave generator is modulated to eliminate hysteresis effect in scanning coil. In addition, leading edge of rectangular-waveform current signal is timed at definite offset relative to peaks of triangular-waveform current signal so as to distribute return points on electron beam route in second scanning direction.
