    1. Preamplifier, HAMPack PM 527

    • HAMPack PM 527 model is a preamplifier that generates a positive bipolar output in response to input signals from photomultiplier's anode from the PMT. Low power consumption and overvoltage protection can extend the life of equipment used together. The compact size also makes it easy to configure with other devices.

    System Features

    Item Description
    Inputs >Nagative charge pulse from scintillation detector
    Outputs Max. amplitude of unipolar positive pulse input from scintilator
    Decay time constant 50 μs
    Rise time <20 ns
    Power supply ±12 Vdc (15mA)
    Operating Temperature Range 0°C to 50°C

    2. Multi Channel Analyzer, HAMPack MCA 123 + MCA 381

    • HAMPack MCA 381 module is a complete Multi Channel Analyzer with integrated bias supply and preamplifier for PMT based detectors.

      It may be used for gamma-ray spectroscopy applications with NaI(Tl), LaBr3(Ce), CeBr3, LBC, SrI2 or similar scintillation detectors. This module is suitable for detectors with 14-pin photomultiplier tubes. All parameters are computer adjustable.
