    摘要: An ion detector includes: a first electron multiplier for detecting first ions having a first polarity; a second electron multiplier for detecting second ions having a second polarity different from the first polarity; a first anode for capturing electrons emitted from the first electron multiplier; a second anode for capturing electrons emitted from the second electron multiplier; and a switching circuit including a first input terminal electrically connected to the first anode, a second input terminal electrically connected to the second anode, and an output terminal, the switching circuit selectively connecting one of the first input terminal and the second input terminal to the output terminal.

    摘要: Techniques are disclosed that can be used to interface a microchannel plate (MCP) with readout circuitry. The techniques can be employed, for instance, with MCP based devices used in a numerous sensing/detection applications, and are particularly suitable for applications where it is desirable to interface an MCP having a relatively large active area to a readout circuit having a relatively smaller active area. The interface effectively decouples anode geometry from ROIC geometry and may also be configured with flexible anode pad geometry, which allows for compensation of optical blur variations as well as a very high fill factor. The interface can be made using standard semiconductor materials and photolithography techniques, and can be configured with thermal expansion qualities that closely track or otherwise match that of the readout circuitry.

    摘要: In this photomultiplier tube 1, light incident on a light-receiving faceplate 3 is converted into photoelectrons by a photosensitive surface 3a, and the photoelectrons strike a dynode 4 to emit many secondary electrons. The secondary electrons are then collected by a mesh-like anode 5. Since the anode 5 is disposed to be parallel to the photosensitive surface 3a, the photoelectrons emerging from the photosensitive surface 3a can easily pass through a mesh portion 5a, and many photoelectrons can be made to strike the dynode 4. As the number of photoelectrons incident on the dynode 4 increases, the number of secondary electrons from the dynode 4 increases. This improves the gain characteristics of the photomultiplier tube 1. Since a secondary electron emission surface 4a of the dynode 4 is tilted with respect to the anode 5, photoelectrons having passed through the anode 5 obliquely strike the secondary electron emission surface 4a of the dynode 4.

    摘要: The magnetic characteristics of a magnetoresistive device are improved by rendering magnetic debris non-magnetic during processing operations. Further improvement is realized by annealing the partially- or fully-formed device in the presence of a magnetic field in order to eliminate or stabilize magnetic micro-pinning sites or other magnetic abnormalities within the magnetoresistive stack for the device. Such improvement in magnetic characteristics decreases deviation in switching characteristics in arrays of such magnetoresistive devices such as those present in MRAMs.

    摘要: A mass spectrometer detector having a coupling capacitor including an anode that is placed at a high potential of say −4.9 kV. An annular electrode is placed outside the anode. A voltage of say −5 kV is applied to the annular electrode. This reduces the potential difference between the anode and the annular electrode, mitigating the electric field. A peripheral electrode is mounted on the outer fringe of a dielectric body and stably held at a potential of say −2.5 kV, for example, by voltage-dividing resistors.
