18 Feb 1975TL;DR: In this article, a magnetically confined sputter-ion vacuum pump with a pair of reactive cathode electrode plates is described, where the cathode plates include peripheral sealing flanges for compressing a sealing gasket into sealing engagement with the main body of the pump.
Abstract: In a magnetically confined sputter-ion vacuum pump a multi-apertured anode electrode is interposed between a pair of reactive cathode electrode plates. An evacuable envelope encloses the anode and cathode electrodes and a magnetic circuit surrounds the vacuum envelope for producing a glow discharge confining magnetic field extending axially of the apertures in the anode. The reactive cathode plates include peripheral sealing flanges for compressing a sealing gasket into sealing engagement with a pair of sealing surfaces at opposite ends of a tubular main body portion of the envelope. A clamping ring structure, having a bolt circle formed therein, serves to clamp the two reactive cathode plates to the main body and also serves as an integral part of the magnetic circuit. Water coolant channels are brazed to the outer surfaces of the cathode plates for cooling same in use. The magnetic circuit includes a pair of ferrite magnets disposed outside the envelope on opposite sides of the cathodes and enclosed by a magnetic yoke to minimize the size and weight of the magnet and to reduce unwanted stray magnetic fields.

05 Jun 1996TL;DR: A solid-state detector for use in an atomic spectrometer comprises a plurality of arrays of sensing elements, or pixels, each of the arrays being positioned along and on the locations of spectral signals on a focal plane of an echelle grating spectrometers.
Abstract: A solid-state detector for use in an atomic spectrometer comprises a plurality of arrays of sensing elements, or pixels, each of the arrays being positioned along and on the locations of spectral signals on a focal plane of an echelle grating spectrometer. The sensing elements are positioned along the many diffraction orders presented on a two-dimensional echelle grating focal plane so that at least one element is located at each and every resolution element regardless of global x-y coordinate positioning of the elements or with reference to each other. The result is a series of skewed lines of sensing elements, those lines being in the same shape as the series of diffraction order lines which comprise an echelle spectrum. The solid-state detector is particularly useful in an atomic spectrometer wherein an echelle grating is used to diffract incident radiation such that the various components of the radiation may be observed.

26 Feb 1932TL;DR: In this article, a method for straightening out the curved mutual characteristic of a vacuum tube was proposed, which is similar to the one described in this paper. But, unlike the latter, this method is not suitable for the case of an electron tube.
Abstract: My present invention relates to a method of controlling the mutual characteristic of an electron tube circuit, and to means for carrying out the new method. More particularly, the invention comprises a method for straightening out the curved mutual characteristic of a vacuum tube, thus gaining...

01 Feb 1973TL;DR: In this paper, double-drift IMPATT devices were fabricated by liquid-phase epitaxial growth of n and p layers on an n+substrate, achieving CW output power 2.35 W with 16.3 percent efficiency at 8.9 GHz and pulse output power 4.1 W with 20.7-percent efficiency at 10.56 GHz.
Abstract: GaAs double-drift IMPATT devices were fabricated by liquid-phase epitaxial growth of n and p layers on an n+substrate. CW output power of 2.35 W with 16.3-percent efficiency at 8.9 GHz and pulse output power of 4.1 W with 20.7-percent efficiency at 10.56 GHz are reported.
