20.500.12556/RUL-101743 Zeemanov upočasnjevalnik cezijevih atomov Zeeman slower for cesium atoms V magistrskem delu opišem eksperimentalni sistem za lasersko hlajenje cezijevih atomov, ki smo ga postavili v Laboratoriju za hladne atome na Institutu Jožef Stefan. Glavni poudarek je na Zeemanovem upočasnjevalniku, ki ga uporabljamo za upočasnitev curka atomov. Predstavljene so teoretične osnove, na podlagi katerih sem naredil njegov načrt, ter postopek izdelave. Primernost narejenega izdelka za uporabo v eksperimentu ovrednotim s simulacijo Monte Carlo upočasnjevanja atomov. V delo vključim tudi meritve, ki smo jih naredili ob prvih preizkusih laserskega hlajenja. Upočasnjevalnik omogoči lovljenje atomov v magneto-optični pasti, v kateri jih nato ohladimo do temperature okoli 1 mK. Končni cilj je ohladitev do nekaj nK. Tu se omejim na opis delov eksperimenta, na katerih smo delali vzporedno z razvojem upočasnjevalnika in ki so neposredno povezani z njegovim delovanjem. In this thesis I describe the experimental setup for laser cooling and trapping of cesium atoms which was developed in the Cold Atoms Laboratory at the Jožef Stefan Institute. I put a special focus on the device which slows down the atomic beam - the Zeeman slower. Its development is described in detail as well as the necessary theoretical background. The suitability of the constructed Zeeman slower is evaluated with the Monte Carlo simulation of the beam slowing process. The description is rounded up with the measurements that were made during the early tests of our laser cooling apparatus. Our Zeeman slower produces a beam of slow atoms which travels towards the magneto-optical trap, where the atoms are cooled down to the temperature around 1 mK. Long-term goal is to achieve the temperatures around few nK, but the entire path towards that goal is not presented in this work. Instead, the description of the experiment is limited only to the components that were developed simultaneously with the Zeeman slower and which are closely related to it. cezij ultravisok vakuum atomski curek lasersko hlajenje Zeemanov upočasnjevalnik magneto-optična past hladni atomi cesium ultrahigh vacuum atomic beam laser cooling Zeeman slower magneto-optical trap cold atoms true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2018-07-01 07:45:07 2018-07-01 07:45:22 2025-08-08 13:20:39 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 87370 3212132 128.pdf 128.pdf 1 39B4D7296E41F9C1F0A540D6238F2B7E ab55d07f1f4cdd661182b16eac8f6e08a9520fbd197aad4eb5a52182666f8789 604356cf-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=111893 Fakulteta za matematiko in fiziko 0 0 0
