The amplitudes of signals (electrical current or light) from a radiation detector are examined using pulse-height spectrometry to estimate the energies of radiations striking the detector or to choose to count only those energies within a specific energy range.
Only detectors like proportional counters, scintillation detectors, and semiconductor detectors that provide output signals with amplitudes proportional to detected radiation energy may achieve this. Such a radiation detector, along with its high-voltage supply, preamplifier, amplifier, and pulse-height analyzer, makes up a pulse-height, or energy, spectrometer.
The Global Pulse height analyzer market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
At the output of a spectroscopic amplifier, the Single-Channel Pulse-Height Analyzer from Ortec is normally proportional to the charge discharged in the detector or to the energy of the observed event. The choice of a variety of energies or charges for these occurrences is analogous to choosing a variety of signal levels at the amplifier’s output.
Single-channel analyzers and discriminators can be used to make this option (SCAs). Only when the input signal of a discriminator exceeds a predetermined threshold level will it generate an output logic pulse. Only when the peak amplitude of the input signal falls within the pulse-height window that is formed with two predetermined threshold levels does a single-channel analyzer generate an output logic pulse.
For selecting a range of output pulse amplitudes from a spectroscopic amplifier for later counting on a ratemeter or counter/timer, the ORTEC Model 550A Single-Channel Analyzer is the perfect tool. For measurements using high-resolution germanium and silicon detectors, it offers the superior stability, resolution, and dynamic range required.
With ionisation chambers, proportional counters, and scintillation counters, these same properties offer performance that is more than enough. The entire instrument is DC-coupled to guarantee that, even at very high counting rates, variations in the counting rate have no impact on the discriminator levels.
