Calibration

Linear (2-point) or quadratic (3-point) calibration is supported.

E[keV] = c1 x2 + c2 x + c3 (x ... Channel Number)

Coefficients will be computed automatically.

Gamma MCA


Common Gamma-Ray Energies


List of gamma-ray energies of common isotopes.
Isotope Energy [keV]


Input in keV. Any positive integer is valid.

File must be of valid JSON format. Use only trusted sources!

File format for downloading a static plot. SVG looks the best.

Any character is valid.

Number of (ADC) channels of the original device. Any positive integer is valid.

Input in bits per second. Any positive integer is valid.

Character transmitted at the end of every single data point. Any character is valid.

Input in seconds. Any positive integer is valid. Serial recording will stop automatically when time runs out.

Input in seconds. Any positive float is valid, use integers for best performance.

Max number of serial input events buffered between plot refreshes. Any positive integer is valid.

Number of (ADC) channels of the serial device. Any positive integer is valid.

Sensitivity of the vertical step size in relation to the highest value. Any positive float is valid.

Width of the overall moving average applied to the plot data that is used as a general reference. Any positive integer is valid.

Maximum distance two peak lines can be apart to count as one single peak. Any positive integer is valid.

Maximum distance to search for isotopes around the peak energy (multiple of the peak width). Any positive float is valid.


Gamma MCA is a complete progressive web app for gamma spectroscopy. It is completely free and open-source with online and offline functionality. You can import spectrum files and record new ones using the serial interface.

For a list of example spectra to help you get started head to the Gamma Spectrum Database.
