Cryogenic gas stopping cell warm tests with ²²³Ra alpha source

Abstract This paper contains information about new setup named as Cryogenic gas stopping cell developed at the Flerov laboratory of nuclear reactions at the Joint institute for nuclear research. The main task of the Cryogenic gas stopping cell (CGSC) is the transformation of the secondary rare ion beams produced in nuclear reactions. These high energy and large emittance beams are converted into low-energy ones with small emittance and low energy spread. Today this setup is under testing stage. The aim of these tests was to obtain the information about optimal technical parameters of the setup and lay the groundwork for the future experiments. The results presented were obtained with the cell at room temperature. This article reports on the initial tests with radioactive sources and covers only a part of the parameters and possible working conditions.
