Here are some screen shots ( in no particular order)  of the new TURSA mca Program, this is a work in progress.

More features are being added daily. Feedback is welcome:  Please email me at

Energy Calibration. In this example the calibration sources are Cs-137 and Co-60. A minimum of three known points are needed to achieve a linear energy scale. The process is simple: obtain a spectrum, enter the known energy and double click on the related peak. Each point can be adjusted either by clicking on the marker flag and dragging it, or by fine adjusting with the Adjust Left/Right button for each peak. Once calibrated the settings can be saved for this particular detector and recalled later.

 NewProg_10.jpg (66694 bytes)After calibration, the user can select to view the raw data spectrum or the energy spectrum. Here is the energy spectrum of Cs-137 and Co-60

NewProg_11.jpg (48709 bytes)If the area of interest is at the low end of the spectrum, it is possible to use a log scale and expand it for better channel separation. Notice data is available well below 10 keV
