Abstract
The main focus of the research program is on studies of hadronic systems (nucleons and light nuclei) by electron scattering (facilities: TJNAF/Jefferson Lab, Newport News and MAMI, Mainz) and on studies of structure and dynamics of heavier nuclei (FAIR facility, Darmstadt), while we also investigate nuclear reactions in which electron shadowing is essential. A fraction of our efforts is dedicated to applied research, in particular analyses involving liquid scintillation spectrometry. Main focus points of research at TJNAF and MAMI: electromagnetic and spin structure of 3H and 3He nuclei, electroweak processes with parity violation on 48Ca nuclei, measurement of spin asymmetry A1n and structure function g2n, measurement of the high-energy part of the GDH integrand, measurement of real Compton scattering at large angles, measurement of inclusive cross-sections on 18Ar, 12C and 16O nuclei, measurement of beam-normal spin asymmetries on 208Pb nuclei. We are involved in the Hall A, Hall B, HallC, Hall D (GlueX) and A1 Collaborations. In parallel with the construction of the Facility for Anti-proton and Ion Research (FAIR), one of the largest fundamental research projects in the world, phase-0 research program is already taking place at the premises and is dedicated to in-beam use of detector systems planned for FAIR, as well as for cutting edge research. This guarantees the operability of FAIR research centre since day one. We have been actively involved in FAIR phase-0 research programme, especially within the NUSTAR physics programme, with studies of the structure and reactions of exotic atomic nuclei, relevant for the creation of the elements in the universe. We have been mostly involved in the HiSpec/DeSpec and SuperFRS collaborations. In The Nuclear Astrophysics Laboratory we study nuclear reactions important for Big-Bang nucleosynthesis. The experiments are performed at our own accelerator and at the Helmholtz Zentrum Dresden-Rossendorf in Germany. We also perform theoretical nucleosynthesis calculations taking into account the effect of electron screening. In the Laboratory for Liquid Scintillation Spectrometry, we continue to develop measurement methods, perform measurements of environmental and industrial samples, participate in the preparation of intercomparison samples and characterization of reference materials, and develop an interactive database.
Significance for science
Research at the TJNAF/MAMI/FAIR facilities The research centers TJANF MAMI and FAIR will enable extraordinary research possibilities with their numerous physics, chemistry, biology and technological programmes in the fields of basic understanding of the creation of matter, astrophysics, material sciences and biomedicine. Research in the Laboratory for Nuclear Astrophysics The Big-Bang theory of the creation of the Universe has three supporting experimental discoveries. These are cosmic microwave background radiation, expansion of the Universe and abundances of light elements in the Universe. The creation of the isotopes of light elements hydrogen, helium and lithium can be well described by the Big-Bang theory. The only problem remains with the abundance of lithium that is predicted to be almost three times as abundant as was observed in the Universe. Our group has added its share to the understanding of this problem. Research at the Laboratory for Liquid Scintillation Spectrometry Fast and accessible measurement methods are interesting for mass use. To be also reliable and traceable, it is necessary to know well their limitations, to carefully prepare calibrations and evaluations of measurement data. This is in principle not in the domain of users who use the method as a tool in other scientific fields, for example in epidemiology, hydrogeology, synthetic chemistry, pharmacy, but on the shoulders of metrology and research laboratories. By accurate validation and upgrading the method for determination of gross ? and ß activity, synchronization of laboratories and modeling the estimation of dose equivalents by measurement results, we will enable the expansion of applications in the field of drinking water, transport of pollutants in groundwater, and offer additional tools to geochemists.
Significance for the country
Basic research facilities The TJNAF, MAMI and FAIR research centres, with their numerous technological programmes and the complexity of its infrastructure, keep providing unprecedented development oportunities and synergies between the academia and the SME segment, in pursuing of new technologies and other high-added-value products. At the same time, such dynamic international working environments offer a unique training experience in technology, leadership and soft skills for young scientists at undergraduate and graduate level. Applied research labs The use of fosil fuels to obtain energy is a highly contentious question in view of the climate change. The main objective of the CleanHME European project is to develop a new, clean, safe, compact and very efficient energy source based on Hydrogen-Metal and plasma systems, which could be a breakthrough for both private use as well as for industrial applications. The new energy source could be employed both as a small mobile system or alternatively as a stand-alone heat and electricity generator. Such a source would not emit greenhouse gases and would present a viable alternative to fossil fuels. The connection of high-tech visionary companies and domestic science is beneficial for both stakeholders, the society and the country: with new knowledge the company gets new momentum and new ideas, science gets new challenges, young intellectuals new opportunities. The competitiveness and visibility of both partners are improved, new jobs and greater added value bring prosperity to the people, and additional resources to the country, which, if it is smart, invests them back into the spiral of success. Several years of cooperation between Melamin d.o.o. and the Laboratory for Liquid Scintillation Spectrometry have been mutually successful, new domestic and foreign entrepreneurs are already knocking on the door, seeing such cooperation as an opportunity. By investing resources and time in understanding the basic laws of measurement methods, we will be better prepared for such cooperation and we will be able to solve the dilemmas of industrial partners by developing liquid-liquid scintillation spectrometry methods for their specific needs more effectively.
