Course: Virtual Instrumentation in Nucl. Physics

Department/Abbreviation: KEF/VIJF

Year: 2016 2017

Guarantee: 'doc. RNDr. Jiří Pechoušek, Ph.D.'

Annotation: During lessons, students will reach knowledge about the principles of digital signal processing in nuclear physics experiments. Practically will be demonstrated methods of analyzing the signals from detectors, recently used in the research.

Course review:
1. Principles of the virtual instrumentation - usage of the LabVIEW, high-performance DAQ systems application, developing of the real-time systems with RTOS (PXI, CompactRIO, FPGA). 2. Synchronization and triggering techniques - signal processing synchronization and signal generation, analog and digital trigger types, how to start measurements. 3. Detector signal processing - types of the detectors (basic characteristics, output signals), digital signal processing, DSP techniques for acquiring/shaping/analysis of impulses, spectrometer dead-time optimization. 4. Amplitude and time signal analysis - how to measure SCA and MCA spectra, methods for impulses pile-up rejection and correction, measurement of the photon/particle time-of-flight (TOF). 5. Design of the Mössbauer spectrometer in VI - principles of the DAQ in MS, synchronization for generation of the source velocity signal and detector signal analysis, data accumulation, physical principles of the Mossbauer effect. 6. Coincidence methods - principles of the coincidence/anticoincidence measurements systems, DSP techniques for TOF determination, how to measure lifetime of the excited nuclear states, design of the time differential Mössbauer spectrometer (TDMS). 7. Distributed nuclear experiments - VI the world experiments.

Případové studie National Instruments

Firma National Instruments, výrobce systémů pro virtuální instrumentaci, publikoval brožuru Příručka případových studií, věnovanou přednáškám, které zazněly na akci NI Academic & Research Days. Jednu kapitolu (str. 128 brožury), věnovanou experimentům v jaderné fyzice, napsal dr. Pechoušek z Katedry experimentální fyziky.

Kniha o aplikacích LabVIEW

V nakladatelství InTechOpen vyšla kniha Practical Applications and Solutions Using LabVIEW™ Software, do které jednou kapitolou přispěl dr. Pechoušek z Katedry experimentální fyziky.
