Abstract: A mass sensor includes a magnet assembly and a mass analyzer. The mass analyzer includes a ceramic housing formed from two end plates and a center portion. The mass analyzer further includes a thermionic electron emitter ionizer, a double focusing mass spectrometer having superimposed orthogonal magnetic and electric fields, and a microchannel plate ion detector located in the housing cavity. The double focusing mass spectrometer includes an electric sector energy analyzer having a film resistor deposited on an inside surface of each end plate. The film resistors are substantially concentric and congruent and have a circular arc shape. Boundary electrodes are positioned adjacent each curved edge of each film resistor. The mass sensor includes a non-evaporable getter mounted inside the housing cavity and external electrical contacts arranged to form a multi-layer printed circuit card that is installable in a circuit card edge connector.

Abstract: A capacitor for connecting to components within a vacuum system in which the space between the capacitor plates is at the pressure of the vacuum system is provided. One of the be plates provides a feed-through which permits closer coupling of the capacit or to other circuits the system and also eliminates the need for additional components. The capacitor can be a mounted and thus thermally coupled to a vacuum manifold which provides temperature stabilization.

Abstract: A method for linearizing the sensitivity of a quadrupole mass spectrometric system to allow the sensor to more accurately report partial pressures of a gas in high pressure areas in which the reported data is effected by a number of loss mechanisms. According to the invention, correction factors can be applied empirically or software in a quadrupole mass analyzer system can be equipped with correcting software to expand the useful range of the mass spectrometer.

Abstract: The invention relates to a cryostat, in particular a helium cryostat with an additional nitrogen tank and a vacuum section, comprising a pressure-relief cover arranged at the outside of the tank wall of the cryostat for closing an opening therein. A locking device by which the said pressure-relief cover is retained in position on the tank wall of the cryostat and which, in its closed position, urges the pressure-relief cover against the edge of the tank opening, under the action of a spring, in such a way that the pressure-relief cover is permitted to be lifted off slightly in the presence of a slight overpressure, against the action of a spring, while in the presence of an important overpressure the locking device assumes its open position in which the pressure-relief cover is released from the tank opening, urges the pressure-relief cover automatically against the tank wall so as to close the opening of the tank edge again after a slight overpressure has been released, but releases the opening when an important overpressure prevails in the cryostat. This arrangement prevents damages to the cryostat and avoids the risks connected therewith.

Abstract: An ion detector system for a mass spectrometer is disclosed comprising an ion detector comprising an array of detector elements. The ion detector system is arranged to correct for tilt and non-linear aberrations in an isochronous plane of ions. The ion detector system generates separate first mass spectral data sets for each detector element and then applies a calibration coefficient to each of the first mass spectral data sets to produce a plurality of second calibrated mass spectral data sets. The plurality of second calibrated mass spectral data sets are then combined to form a composite mass spectral data set.
