An MCA is designed to convert the output from a radiation detector into a digital form that can be analyzed. When a detector, such as a scintillator or semiconductor detector, captures a radiation event (e.g., a gamma radiation), it generates a corresponding electrical pulse. The MCA measures the amplitude of these pulses, which corresponds to the energies of the incident radiation. These pulses are then sorted into channels based on their amplitude, producing a spectrum that can be used for identification the type of radiation and the isotopes present.

| Tubebase Multi Channel Analyzer (MCA) |
A tube base multichannel analyzer (tube base MCA) is a specialized type of MCA designed to interface with tube-based scintillation detectors, particularly photomultiplier tubes (PMTs). These detectors are commonly used in scintillation detector to measure the intensity of light emitted by scintillator materials in response to ionizing radiation. The tube base MCA facilitates the coupling of the PMT to the MCA, enabling efficient signal processing and analysis of the pulse signals from the tube. Tube base MCAs are particularly useful in environments where high sensitivities and low background noise are critical.
