Gwiazdy bozonowe oraz gwiazdy fermionowe mogły powstać we wczesnym Wszechświecie podczas grawitacyjnego przejścia fazowego pierwszego rzędu. Być może część z nich zachowała się do dziś. Poszukiwania ich obejmują przede wszystkim centralne części galaktyk. Soczewkowanie grawitacyjne jest jedną z metod obserwacyjnych, która może pomóc je znaleźć.

Boson stars and fermion stars may have formed in the early universe during a first-order gravitational phase transition. Perhaps some of them have survived till now. The search for them covers mainly the central parts of galaxies. Gravitational lensing is one of the observational methods that can help find them.

ILC machine–International Liner Collider, is one of two accelerators e+e-just under design and advanced consideration to be built with final energy of colliding electron and positron beams over 1 TeV. An alternative project to ILC is CLIC in CERN The ILC machine is an important complementary addition for the research potential of the LHC accelerator complex. The required length of ILC is minimally 30 km, but some versions of the TDR estimates mention nearly 50km. Superconducting RF linacs will be built using well established 1,3 GHz TESLA technology using ultrapure niobium or Nb3Sn resonant microwave cavities of RRR class, of ultimate finesse, working with gradients over 35MV/m, while some versions of the design mention ultimate confinement as high as 50MV/m. Several teams from Poland (Kraków. Warszawa, Wrocław – IFJ-PAN, AGH, UJ, NCBJ, UW, PW, PWr, INT-PAN) participate in the global design effort for this machine – including detectors, cryogenics, and SRF systems. Now it seems that the ILC machine will be built in Japan, during the period of 2016-2026. If true, Japan will turn to a world super-power in accelerator technology no.3 after CERN and USA. The paper summarizes the state-of-the-art of technical and administration activities around the immense ILC and CLIC machines, with emphasis on potential participation of Polish teams in the global effort of newly established LCC –The Linear Collider Consortium.

Artykuł opisuje rozwój wiedzy o budowie materii, poczynając od czasów starożytnych, kończąc na obecnym stanie wiedzy. Omówione zostały starożytne indyjskie i greckie teorie atomu, podejście alchemików, rozwój współczesnej chemii pozwalający na wprowadzenie pojęcia pierwiastka, atomu, elektronu, historyczne modele budowy atomu: model Thomsona, Rutherforda, Bohra i Gryzińskiego. Krótko omówione zostały wybrane zagadnienia chemii kwantowej. Na koniec podsumowano obecny stan wiedzy o budowie atomu a także cząstkach elementarnych.

EN

The development of the knowledge on the matter structure was described, from ancient times to present. The ancient Indian and Greek theories of atom, the alchemists point of view were demonstrated, as well as the development of modern chemistry leading to the concepts of element, atom and electron. The historical models of atom structures of Thomson, Rutherford, Bohr and Gryziński were shortly discussed. The selected problems of quantum chemistry were briefly described. In the conclusion the present state on atom structure and elementary particles was summarized.

Accelerators are basic tools of the experimental physics of elementary particles, nuclear physics, light sources of the fourth generation. They are also used in myriad other applications in research, industry and medicine. For example, there are intensely developed transmutation techniques for nuclear waste from nuclear power and atomic industries. The European Union invests in the development of accelerator infrastructures inside the framework programs to build the European Research Area. The aim is to build new infrastructure, develop the existing, and generally make the infrastructure available to competent users. The paper summarizes the first year of activities of the EU FP7 Project Capacities EuCARD - European Coordination of Accelerator R&D. Several teams from this country participate actively in this project. The contribution from Polish research teams concerns: photonic and electronic measurement - control systems, RF-gun co-design, thin-film superconducting technology, superconducting transport infrastructures, photon and particle beam measurements and control.

Opisano działania koordynacyjne badań naukowych, od podstawowych po wdrożeniowe, w dziedzinie techniki akceleratorowej na terenie Europy w latach 2003-2009. Badania te nie były specjalnie skoordynowane w Europie i raczej skupiały się wokół kilku ośrodków dysponujących dużą infrastrukturą badawczą, takich jak CERN, DESY, GSI, INFN, LAL, PSI. itp. Dzięki tym akcjom koordynacyjnym wiele badawczych ośrodków krajowych mogło znacznie łatwiej pogłębić i rozszerzyć lub wręcz rozpocząć swoją przygodę naukowo-techniczną z techniką akceleratorową. Opisano Europejskie programy ramowe techniki akceleratorowej CARE i EuCARD, ich zakres prac, oraz udział w nich ISE PW.

EN

There are described coordinating actions of the accelerator science in Europe in 2003-2009. The actions embrace basic science, as well as development and applications. The accelerator research was not coordinated in Europe at a global scale but was rather concentrated in a few centers owning large infrastructure. These centers include: CERN, DESY, GSI, INFO, LAL, PSI etc. Such coordinating actions enable a lot of positive processes including new possibilities for research centers in this country. It is much easier for them to extend, deepen or even start from the beginning their adventure with the accelerator technology. There are described two European framework projects CARE and EuCARD on accelerator technology, their extent and the participation of ISE WUT in them.
