    EA amplifiers / Lock-in EA amplifier

    EA amplifiers are complex multi-stage amplification systems with integrated current & voltage sources for Electrical Analysis. All versions feature a high-speed transimpedance preamplifier for imaging, a bandwidth filter and a flexible second-stage amplifier for imaging. High-precision voltage and current sources are integrated into the compact housing, as required for biasing, IV sweeps and compensation. Packaging is miniaturised in order to reduce cable lengths, increase speed and optimise signal-to-noise ratio.

    HT BSE detector

    Electrode-based detectors are specially designed for in-situ High Temperature experiments where conventional detectors cannot be used. This is, because light and thermal electrons emitted by the hot sample easily saturate the electronics, and because the unavoidable contamination from the in-situ conditions limits the lifetime of delicate sensors.

    In this new design, BackScattered Electrons (BSE) are absorbed in robust electrodes (metal plates) placed at the detection plane, the resultant absorbed current is preamplifier in-situ, and then amplified and mixed further ex-situ. Secondary and thermal electrons are repelled away, as a bias voltage is applied to the electrodes through the detector galvanic isolation. Light, either emitted from the hot sample, or scattered from a laser heater, does not produce signal in such technology, the detector is inherently light-blind.

    Electrodes can be coated in various materials to optimise absorption efficiency at particular energy ranges, e.g. Carbon coating for higher acceleration voltages, and can be easily disassembled, cleaned and recoated.

    Of course, four quadrant electrodes are used to enable 3D surface analysis when combined with our calibrated SEM scan controller (DISS6) and Topographic reconstruction software.

    Easy to clean

    * Electrodes can be cleaned and recoated as needed

    High Temperature
    * Electrodes are blind to light emitted by hot samples
    * Thermal electrons are filtered using the detector bias
    * Maximum temperature limited only by radiative heating
    * Compatible with laser heating

    Quantitative measurements
    * Electronic gains, offsets and bias are factory calibrated
    * Amplification is temperature stabilized
    * Current collected into sensing electrodes is measured
    (when combined with calibrated Scan controller for SEM (DISS6) and COMPO calibration sample)

    Surface analysis
    * TOPO and COMPO mix is done in the detector hardware
    * 4Q signals are designed for topographic reconstruction
