摘要： A multiplication register for use in solid state imaging apparatus, such as a CCD, is described. The multiplication register has a gain element 22 comprising a plurality of register electrodes 30, 32, 34, and 36, for transferring charge along a change transfer channel, and for amplifying the charge. Channel edge defining electrodes 24 and 26 are disposed either side of the channel 28, in place of channel stops, removing the effects of spurious charges generated in the channel in the regions of amplification. The provision of the channel edge defining electrodes 24 and 26 allows the resulting structure of the channel electrodes to be made simpler, and means that a structure can be provided for clocking and amplifying charge in either direction along the channel.

摘要： Effective sensitivity of a photodetector of an image sensor is controlled by partitioning signal charge from incident photons, thus producing a manageable yield and a consequently higher, photon shot noise limited, signal to noise ratio than in the prior art, when imaging high flux rates of energetic photons or particles, such as produced by x-ray generators. The invention may be applied, for example, to an image sensor with a photosensitive layer coupled to a charge collection/readout structure, e.g. photoconductor or scintillator on CMOS array, or to an intrinsically sensitive charge collection/readout structure, e.g. deep active layer CMOS. A radiation sensor pixel structure 10 for use in the invention includes a photodetector 11, a transfer gate 131 for controlling charge collection from the photodetector and a dump drain 12 controlled by a dump gate 121, arranged for selectively dumping charge to the dump drain means and collecting charge from the photodetector means, in a duty cycle 31, for varying effective sensitivity of the pixel structure. An image sensor containing such pixel structures may selectively be operated in an integration mode or a photon counting mode. Preferably the image sensor has imaging pixels and control circuitry arranged on a same semiconductor die, such as a CMOS semiconductor die.

A first readout circuit is provided for reading out charge from the first node. In use a first charge accumulated in the photodetector from a first predetermined portion of an energy spectrum of a radiation source is transferred to the first sense node. A second charge is accumulated in the photodetector from a second predetermined portion of the energy spectrum. The first charge is readout from the first sense node with the readout circuit, the second charge transferred to the first sense node and likewise readout. In embodiments of the invention, a second sense node and second transfer gate are provided and the first charge is read out through a first sense node and the second charge through the second sense node. In further embodiments a dump drain controlled by a dump gate is also provided to permit duty cycle control of sensitivity of the photodetector by selectively dumping and storing of charge accumulated in the photodetector.

摘要： In a magnetron having a body 1 defining an anode 2 divided into resonant cavities 4 by vanes 3 and having a coaxial cathode 5, r.f. energy produced when a magnetic field is applied parallel to the axis of the anode is launched along a waveguide 8 by an antenna 6 in an evacuated region of the magnetron closed by a dielectric window 19. The latter has sector shaped conducting areas on its surface symmetrically arranged with respect to the antenna, the inductance of which balance the capacitance of the dielectric window, thereby reducing reflections at the window.

摘要： Vertical and horizontal smear in images produced by a CCD imager can be compensated for by detecting the boundaries of the smear and substituting data from an alternative part of the image, or interpolated data within those boundaries. Vertical, or frame transfer, smear can also be compensated for by producing an error signal from charge accumulated during frame transfer and corresponding to one or more masked rows of the CCD imager. This error signal can be subtracted from the line signals corresponding to each row of the CCD images receiving radiation during image acquisitions. The CCD imager includes a multiplication register. The dynamic range of the imager may be extended by varying the gain of the multiplication register, for example on a line-by-line or frame-by-frame basis.

摘要： A cooling arrangement for an electron collector of an electron beam tube has a plurality of solid dielectric spacers surrounding the corrector with an electrically insulative and thermally conductive dielectric liquid in gaps between the spacers. A water cooling system is arranged in thermal contact with the spacers and the liquid dielectric to provide cooling by water circulation. The cooling arrangement is a hybrid of oil and water cooling systems in which the electrically non conductive oil is arranged in gaps between dielectric spacers, the dielectric spacers provide a support for the surrounding water coolant system and ordinary water may be used to be pumped through the water cooling system.

摘要： A system for time resolved spectroscopy comprises a CCD device arranged to receive a time varying spectrum. Time resolved spectroscopy is the analysis of a spectrum that varies with time due to any cause. The variation with time of the spectrum may be due, for example, to (i) changes of the spectrum from a given sample space with time (such as due to emission decay); and (ii) changes in the spectrum as successive portions of a sample space are sampled (such as laser scanning microscopy). The CCD device comprises an array of photosites arranged to detect the time varying spectrum and to produce signal charge representative of the spectrum, and one or more CCD multiplication registers arranged to receive the signal charge and to provide charge multiplication. An enhancement of speed and sensitivity is given by a storage area which receives the signal charge in parallel from the array of photosites to provide the charge in serial to the one or more multiplication registers.

摘要： A detector assembly for detecting the presence of analyte molecules, in particular, proteins, uses both Surface Enhanced Raman Scattering (SERS) and Surface Plasmon Resonance (SPR) in synergy. The excitation laser used for SERS provides scattering from a reporter dye to which an analyte molecule is attached in the vicinity of a conducting surface. Simultaneously, a second laser is provided at the critical angle to the conducting surface. The second laser causes a field to be created in the region of the analyte which enhances the Raman scattering effect.
