IBM PC controller for Bruker EN250 ENDOR system

Module upgrading the existing IBM PC data acquisition and processing system for Bruker ER200D equipped with EN250 ENDOR attachment is described. The old ASPECT 2000 computer is fully replaced by a modern IBM PC without any modification of the Bruker EN003 ENDOR standard interface. Thus the spectrometer can operate under IBM PC control in ENDOR and TRIPLE modes. Moreover its features are extended with ENDOR INDUCED EPR operating mode which was not available before.

Simulation of transmission coefficient through a triangular potential barrier

An analytical expression of the transmission coefficient for the electron transport through a triangular potential barrier has been modified for solution using the method of numerical simulation. The triangular potential barrier has been modelled as a staircase function. The performance of this numerical simulation method is briefly described. The simulation has been developed for personal computer IBM PC AT.

Automated measurement of ac impedance data: Acquisition and analysis

A set of algorithms (the IONICS systems) for the acquisition and analysis of ac impedance data in superionic conductivity research using an IBM PC compatible computer, have been developed and tested extensively. The algorithms can be used for acquiring ac impedance data at different frequencies as a function of temperature. The furnace can also be controlled simultaneously. The data can then be graphically displayed and numerically fitted with the appropriate curves, i.e., straight lines on Arrhenius plots and arcs of circles complex impedence plots. This paper describes the IONICS system, which consists of three modules ACQUIRE, ANALYSE and GENERATE.     

An automatic image analysis system for the evaluation of dielectric track detectors

The automatic image analysis system for scanning solid state nuclear track detectors is designed by utilizing a microdensitometer. The control of the entire system as well as the data analysis are accomplished with the IBM PC computer equipped with a FrameGrabber. The system counts the number of tracks and measures their geometrical parameters. The usage of the system is illustrated by counting rhombic tracks in mica detectors which were used for the investigation of the fusion–fission reaction ¹²C+ ²⁰⁸Pb.
