The design of nuclear spectrum data processing based on the technology of ARM and touch screen

Considering the traditional nuclear spectrum data processing system based on PC which has a lot shortcomings, such as high power consumption, large volume and not suit for site operation, etc. Start from the user-friendly design in this paper, the portable nuclear spectrum data processing system based on ARM embedded processor and serial touch screen has been completed. The system has the function that spectral data display, energy calibration, spectrum smooth, peak searching, peak area calculation and energy calculation. So ARM embedded and touch technology have good development prospects in the field of nuclear instrument. (authors)
