    Abstract: In order to meet the needs of the semi-conductor industry as it requires finer lithography nodes, a method of feedback control for scanning probe microscopy generates a microwave frequency comb of harmonics in a tunneling junction by irradiating the junction with mode-locked pulses of electromagnetic radiation. Utilizing power measurements within one or more harmonics, the tip-sample distance in the tunneling junction may be regulated for maximum efficiency and avoid tip crash when used with resistive samples. Optionally, no DC bias is required to use the method.

  • Patent number: 10054696
    Abstract: A detector for an electron multiplier comprising: a substrate comprising a dielectric material, the substrate having a first face and an opposing second face; a charge collector provided adjacent the first face of the substrate; an anode within the substrate, the anode spaced from first face, such that the anode is capacitively coupled to the charge collector, so that charge incident on the charge collector generates an image charge on the anode; and a conduit contact, coupled to the anode and passing through the substrate to the second face of the substrate layer.

  • Patent number: 10006808
    Abstract: A method of adjusting a gain of a detector is provided in the present disclosure. According to an example, whether a gain of a photomultiplier tube in the detector meets a gain determination condition may be determined, where the gain determination condition may indicate that an absolute of a difference between the gain of the photomultiplier tube and a target gain is within a predetermined numerical range. When the gain of the photomultiplier tube does not meet the gain determination condition, a voltage of the photomultiplier tube may be adjusted, such that the gain of the photomultiplier tube meets the gain determination condition.

  • Patent number: 9941103
    Abstract: A bias-variant photomultiplier tube (PMT) includes a photocathode that when operating absorbs photons and emits photoelectrons responsive to the absorbed photons. The bias-variant PMTO also includes a plurality of dynodes that receive the photoelectrons emitted by the photocathode. The plurality of dynodes include a first pair of dynodes having a first bias difference and at least a second pair of dynodes having a second bias difference. The second bias difference is greater than the first bias difference. The bias-variant PMTO also includes an anode to receive photoelectrons directed from the plurality of dynodes.

  • Patent number: 9927603
    Abstract: A switch which reduces the voltage between the photocathode and the first dynode in the activated switching state compared to the deactivated switching state and a control unit which is adapted to move a target spot, which can be illuminated by means of the light source, over a scanning field by means of a deflecting unit. The control unit activates the switch when the target spot enters a given region of the scanning field and deactivates the switch when the target spot exits the region.

  • Patent number: 9930276
    Abstract: Methods of measuring and calibrating the gain of a CCD imaging system are described. Charge injectors may be present on either side of an image sensor array that provide test charges to respective calibration VCCDs. Test charges may be transferred to upper and lower HCCDs during quad-output read out or to only the lower HCCD during dual-output or single-output read out. In each quadrant of the imaging system, test charges may be transferred to an EMCCD output or to a non-EMCCD output via a charge switch based on the magnitude of the test charges. The gains of all EMCCD outputs and non-EMCCD outputs in the imaging system may be calibrated against one another by adjusting the gain at each output when a discrepancy is detected between any two outputs.
