Significance for science
The construction and successful operation of the aerogel Cerenkov counter has now enabled us to do the following important steps in the experimental studies of hadronic systems and processes involving strangeness: * we are now able to measure Lambda and Sigma hyperon production near threshold with large acceptances. All previous measurements (Hall A and Hall C were made with very limited acceptances and therefore suffered in terms of rates). The first results on kaon angular distributions have already been obtained. * we are able to make significant advances in precision studies of the structure of hypernuclei; by measuring the kaon angular distributions, the bound Lambda wave function inside the hypernucleus can be mapped out. This requires the operation of the KAOS magnet as a fully instrumented double spectrometer under zero degree, including the Cerenkov detector. This measurement also makes highest demands on the background suppression on the trigger level and on the momentum resolution. A high-performance Cerenkov counter that we have constructed is therefore one of the key ingredients. * we are now in the position to study the coherent production of K+K- pairs on nuclei. The production of low-momentum phi mesons within nuclei will offer unique possibilities to study the behaviour of strange mesons under quasi-stationary conditions in cold nuclei at normal nuclear density.
Significance for the country
The immediate importance of the executed project for the society and for the industrial companies is twofold. Our research groups works in the field of physics in which the researchers obtain an unusually broad spectrum of knowledge, and these researchers become highly sought-after in the work market after they complete their education or research cycle within our group, and mostly act as leaders in the respective companies. At the same time, by getting to know the different new technologies (mostly highly sensitive photon detection as well as custom-made electronic circuits for data acquisition at high count rates) within this project, the researchers will now be able transfer these techniques and the accompanying know-how into Slovenia, where they will be made accessible to various high-tech companies. The finished project has also had a large influence on the promotion of the country, on the access to foreign know-how, on the way physicists overlap internationally, as well as on the education of young researchers. By collaborating in the MAMI/A1 Collaboration at Mainz, where presently more than 100 physicists from several European countries, Japan, and the United States participate, we have been at the very front of hadronic physics research. At the same time, our group itself has contributed to the knowledge of this large and experienced group of physicists and thereby contributed to the promotion. We have always been treated as equal partners, coming from sound, high-quality research and education environments. Education has been one of the main by-products of our research work at the MAMI facility at Mainz. In this finished project, above all young propulsive researchers have shown their best, got educated at the best source of knowledge, and have absorbed this know-how and port it to their home institution.
