On the Research Field of Nuclear Measurements we mainly deal with analog electronics (low-noise, low-distortion, high-speed preamplifiers, charge-sensitive preamplifiers, analog-to-digital and digital-to-analog converters, multichannel analysers) and interfacing them to standard bus systems such as ISA, CAMAC, VME, VXI. Our experts on Nuclear Measurements are working together with physicists from Hungary, Germany, France and the international research community at CERN. We are members of the ESONE committee since 1971.

In the frame of nuclear measurement research a new high resolution low noise (Full Width at Half Maximum FWHM: < 1keV), charge-sensitive preamplifier array have been developed for multistrip Ge-detectors, elaborated at KFA Jülich, Germany. The new generation of detectors needs a large number (200) of high-resolution amplifiers in a small area. Two versions of the pre-amplifier have been realised. The first has a separate input FET that is in the cooled area (liquid nitrogen), the second one is very compact (the size of the PCB is 45 mm by 22 mm) and the last one is the small outline version(27x15mm) these contain the FET on the board.

Further processing element of the detector electronics chain, a shaper amplifier was also developed. On a VME board, the 16 Channel Shaper Amplifier Module, serves to receive the output signals from a set of detectors, preamplifiers. It converts the low-level output signals of the preamplifiers by programmable gain and by jumper selectable integrating and differentiating time constants into suitable form for further processing (e.g. multi-channel analysing). Typical application is the use of the module as a main shaper-amplifier after multiple charge sensitive amplifiers with multi-strip detectors.

In the frame of project NA49 heavy-ion collision experiment at CERN (Geneva, Switzerland) a large set of measuring instruments, the so called BUDAPEST WALL was developed at KFKI Research Institute for Particle and Nuclear Physics with the participation of our experts. A Constant Fraction Discriminator (CFD) VME board was developed, as part of the 320-channel measuring system. Later the measuring system at NA49 was extended with further 640 channels of our CFD VME modules in a co-operation with German researchers from University of Marburg.

As a further project, a TOF spectrometer system based on a tower of 20 Pestov counters with a new, very compact electronic time measurement and read-out system was installed. The development, testing and production of the 640-channel high-resolution (40/50ps) TDC-System for the TOF spectrometer system was carried out by the experts of MTA-ITA, LAI.

An other field of application: a monitor system for heat-exchangers was developed and built by our nuclear group in co-operation with Paks Nuclear Power Plant (Hungary) and the Institute for Nuclear Technology of the Technical University of Budapest (Hungary). This system is now in use at the Paks Nuclear Power Plant.

In the frame of Cooler Synchrotron Project COSY JÜLICH a Beam Position Monitor Electronics was developed according to the specification of KFA Jülich to diagnostics and optimise the closed beam orbit and to study its dynamic behaviour. The BPM electronics consists of very low-noise preamplifiers (BPMeP), analog signal processing modules (BPMeA) and digital control and decoding modules (BPMeD). The sensing of the particle beam position was carried out by horizontal and vertical beam-detectors connected directly to the BPMeP preamplifiers. Such electronic assembly was installed at 31 points along the 183,4m ring of the COSY. All the above mentioned electronic devices were developed and realised by our experts.
