Laboratory of Nuclear Physics in Piešťany

Head of laboratory:Mgr. Martin Venhart, PhD.

The laboratory is equipped with two electrostatic accelerators at low energies, a set of detectors to measure X-rays, gamma rays, charged particles and neutrons. For processing the signal from the detectors Digital and Analog electronics is available. The laboratory is equipped also with powerfull working station to process the information from experiments.

Detectors of nuclear radiation with electronics

Analytical X-ray microscope Horiba XGT 7200

Analytický RTG mikroskop Horiba XGT 7200 umožňujúci prvkovú analýzu vzoriek, meranie hrúbky terčov a pod.


Tape transport system TATRA

TApe TRAnsportation system

Tape transport system TATRA originally developed for the experiment IS521 at CERN-ISOLDE facility. The system allows the transport of radioactive samples generated beam deposition on the metal strip. The unique properties of vacuum and radiation resistance of the materials that have been specially developed for this purpose, the IP SAS, makes this system one of the best of its kind in the world

Digital data collection system from radiation detectors

Digital data collection system from radiation detectors based on the digitizer Pixie-16. The system is equipped with three cards of the same type (i. e., 48 channels) with a frequency of 250 MHz and a resolution of 14 bit. Digitizers are accompanied by a time-to-digital converter type Acquiris with a resolution of 5 ps and 12 independent channels. The whole system works on PXI bus type that control and communicate with a PC via fiber optic cable.


Analog data collection system

Analog data collection system based on an amplitude-to-digital converter with 4096 channels is based on CAMAC format.

Planar Si(Li) detector

Planar Si(Li) detector with a thickness of 5 mm and a surface area of 80 mm2 with a removable beryllium windows, and cooled with liquid nitrogen. The detector can be used to measure gamma radiation at low energy, and detecting the conversion electrons with high resolution. The detector is placed in the shift cryostat, which allows the separation of the vacuum in the measurement chamber.
