PRECISE COMPACT SYSTEM FOR IONIZING RADIATION DETECTION AND SIGNAL PROCESSING WITH ADVANCED COMPONENTS INTEGRATION AND ELECTRONIC CONTROL

Quality and performance of a detection system are the crucial parameters in all nuclear physics experiments. This system serves as a source of all signals and noises to be processed. Better performance, higher amplification and lower noises occurrence simplify subsequent signal analysis. In the field of Mossbauer spectroscopy, the spectrum quality and Mossbauer effect are crucial parameters which are affected especially by the quality of the detection system. These parameters were evaluated for different types of a detection setup. Finally an improvement of the spectrum quality by 15% and Mossbauer effect by 7% has been achieved for the natural iron reference absorber measurement in comparison with previous version of the detection system.
