Description
Summary:The application of a gas cell filled by noble gas (He or Ar) for thermalizing, storing and transporting trace radioactive ions and atoms has been studied in off-line conditions. Two-step laser resonance ionization has been used to produce ions of stable and long-lived radioactive isotopes inside the cell. The interactions of ions with impurity molecules, with noble gas atoms, with electrons and with electrical fields have been investigated in order to specify the requirements for the gas cell as a source of radioactive rare isotopes for the next generation radioactive ion beam facilities. Extraction and transport of ions by the sextupole ion guide (SPIG) without applying DC electrical field allows to get information about the gas purity and about chemical reactions which take place inside the gas cell.
