    Abstract: Components of scientific analytical equipment, such as electron multipliers and modifications thereto, for extending the operational lifetime or otherwise improving performance by way of improved construction. A detector includes one or more electron emissive surfaces and one or more detector elements configured to define on one side an environment internal the detector and on the other side an environment external the detector. The one or more detector elements are configured to inhibit or prevent flow of a gas from the environment external the detector to the environment internal the detector. Such detectors may be used in a mass spectrometry instrument, for example.

The apparatus includes a housing (20), a window (26) at least partially transparent to electromagnetic radiation in a first wavelength range and a photomultiplier tube (24) for generating an electrical output signal dependent on the intensity of the electromagnetic radiation. A resiliently deformable optical coupling (28) is located between the window and the photomultiplier tube for allowing at least some electromagnetic radiation passing through the window to enter the photomultiplier tube, and a scintillator element 8 converts gamma radiation into visible light in the first wavelength range entering the photomultiplier tube.

    Abstract: In a micro-channel plate, an electron emission film and an ion barrier film formed on a substrate are integrally formed by the same film formation step. In this structure, the electron emission film and the ion barrier film are made as continuous and firm films and the ion barrier film can be made thinner. Since the ion barrier film is formed on the back side of an organic film, the organic film is exposed during removal of the organic film. This prevents the organic film from remaining and thus suppresses degradation of performance of the ion barrier film due to the residual organic film, so as to suppress ion feedback from the micro-channel plate and achieve a sufficient improvement in life characteristics of an image intensifier.

    Abstract: In an electron tube, an electrical resistance film having a stacked structure of electrically insulating layers and electrically conductive layers is formed on holding surfaces of bases in insulating substrates. This electrical resistance film is made as a firm and fine film with a desired resistance by use of an atomic layer deposition method, which can suppress electrification of the bases comprised of an insulating material. This makes it feasible to stably maintain withstand voltage characteristics.

    Abstract: Disclosed herein is a PhotoMultiplier Tube (PMT) designed for use with a surface inspection system such as the Surfscan system, which operates at 266 nm wavelength. The inventive PMT is high efficiency, low noise, and low gain, a combination of features that is specific to the application and contrary to the features of PMT's in the art. The inventive PMT is designed to be tuned to a specific narrow band wavelength of incident light, thereby optimizing the QE at that wavelength. It is further designed to combine a small number of dynodes each having substantially higher secondary electron gain than typical dynodes. By designing the PMT in this way, the excess noise factor is dramatically reduced, yielding a much improved S/N, while still maintaining the overall PMT gain in the lower range suitable for use in a surface inspection system.
