W artykule przedstawiono przygotowanie struktury miedzianej typu TESLA do pracy w laboratoryjnym stanowisku testowym. Krótko opisano podstawowe właściwości wnęki rezonansowej typu TESLA, a także jej zastosowanie do przyspieszania cząstek naładowanych w akceleratorach. Omówiono procedurę strojenia struktury do częstotliwości 1,3 GHz, konstrukcję stanowiska testowego wyniki testów strojenia struktury oraz sterowania wnęką miedzianą poprzez tor RF i elektroniczny system LLRF.

The idea of building a new IVth generation of light sources of high luminosity, which use accelerators, arose in the 80ties of XXth century. Now, in a numerable synchrotron and laser laboratories in Europe, an intense applied research on free electron lasers has been carried out for a couple of years (FEL) [17,18]. Similarly, in this country, free electron laser in Poland - POLFEL [9] is in a design, a coherent light source of the IVth generation, characterized by very short pulses in the range of 10-100fs, of big power 0,2GW and UV wavelength of 27nm, of average power 1W, with effective high power third harmonic of 9nm. The laser consists of a linear superconducting accelerator 100m in length, undulator and experimental lines. It generates a monochromatic and coherent radiation and can be tuned from THz range via IR, visible to UV, and potentially to X-rays. The linac works in quasi-CW or real-CW mode. It is planned by IPJ [9,10] and XFEL-Poland Consortium [16] as a part of the ESFRI [1] priority Euro FEL infrastructure collaboration network [6], part of the European Research Area - ERA [2]. The paper discusses: FEL background in Poland as a part of EuroFEL infrastructure, FEL parameters and performance, FEL research and technical program and FEL networking in Europe and worldwide. Emphasis is put on the usage of superconducting RF TESLA technology and ties linking Polfel and the European X-Ray Free Electron Laser. The Polfel team of researchers is now dissipated worldwide among such projects as Flash and E-xfel in Desy, Cebaf in JLab, Alba in Barcelona, Elettra in Trieste, ILC in Fermilb, LCLS in SLAC. Polfel creates an unique, but quite transient chance to gather and solidly accumulate for a long time this expertise in this country again.

Rozwój techniki akceleratorowej w Polsce jest ściśle powiązany ze współpracą ze specjalistycznymi ośrodkami dysponującymi akceleratorami na świecie. gdzie jest generowana odpowiednia wiedza pozwalająca na budowę dużych i nowoczesnych maszyn. Są to przedsięwzięcia relatywnie kosztowne o charakterze interdyscyplinarnym. Znaczna część z nich jest finansowana lokalnie. Tylko największe maszyny są finansowane wspólnie przez wiele państw jak LHC w Cernie. ILC w Fermilabie i E-XFEL w Desy. Podobnie musi być w Polsce, gdzie trwa obecnie kampania naukowa i polityczna na rzecz budowy dwóch dużych maszyn: Polskiego Synchrotronu w Krakowie oraz Polskiego lasera na swobodnych elektronach POLFEL w Świerku. Wokół tych dwóch bardzo dużych projektów naukowo-technicznych realizowanych jest kilkadziesiąt mniejszych.

The development of accelerator technology in Poland is strictly combined with the cooperation with specialised accelerator centers of global character, where the relevant knowledge is generated, allowing to build big and modern machines. These are relatively costly undertakings of interdisciplinary character. Most of them are financed by the local resources. Only the biggest machines are financed commonly by many nations like: LHC in Cern, ILC in Fermi Lab, E-XFEL in Desy. A similar financing solution has to be implemented in Poland, where a scientific and political campaign is underway in behalf of building two big machines, a Polish Synchrotron in Kraków and a Polish FEL in Świerk. Around these two projects, there are realized a dozen or so smaller ones.
