| Outline of Final Research Achievements |
We have successfully tested the use of ion surfing rf-carpet, both online and offline. The initial offline results were published last year. Newer offline results have been published in the Master Thesis of Arai Fumiya at University of Tsukuba. These newer results have shown that we can use higher pressure than expected in a large gas cell to be used online at RIKEN. The large gas cell will be the basis of a low-energy nuclear physics facility and higher pressure will mean higher efficiency.
The new rf-carpet has been used in online commissioning of a small gas cell for fusion-evaporation reactions products. The goal of this facility is to measure trans-Uranium elements, eventually providing anchor points for hot-fusion reactions which will aid in precise determination of new super-heavy elements.
The new rf-carpet tested online more than 30% efficiency while providing good differential pumping. Initial results will be published in scientific journals soon.
