Fair-wind gas cell for the UniCell setup

Abstract

A novel UniCell setup for studies of superheavy elements (SHE) was proposed recently. Here we deploy the concept of the so called ”Fair-wind gas cell” and suggest a new buffer gas stopping cell, that may serve as an optional main part of the UniCell setup. Advantages of this new optional gas cell compared to the previous version for the UniCell setup consists in the use of an intense compulsory buffer gas flow, as a driving force for ion transport through the high-density gas stopping cell, combined with an RF-only funnel. This allows a fast and highly efficient extraction of ions from the gas stopping cell without application of traditional DC gradient fields. For the reduction of the pure buffer gas consumption the intense flow is recirculating in a loop. The functionality of the proposed new gas stopping cell was explored by detailed gas dynamic and Monte Carlo ion-trajectory simulations, the results of which are presented and discussed. They demonstrate the feasibility of the fair-wind gas stopping cell for the application in SHE research.
