European network on developing techniques for effective slowing down, stopping in a gas cell, and extraction of radioactive ions

Objective

Description:

Objectives:Physics with high-quality, low-emittance and low-energy radioactive ion beams is a forefront topic of current nuclear physics research worldwide. The main objective of the ION CATCHER network is to develop and improve techniques for effective slowing-down and stopping of radioactive ions in a gas cell followed by an efficient extraction. These manipulation must be fast because of short half-lives, efficient because of small production rates and selective to avoid contaminations. The network combines all expertise on this field available in Europe both from Large Scale Facilities and university groups. Project tasks comprise the investigation of the stopping ranges of ions in medium and high-pressure gas (10 mbar to 10 bar), the study of charge and weak plasma effects in the gas cell as well as of the ion chemistry in the cell. Technological developments aim at the development and test of an energy- and range bunching system and an optimisation of gas purification systems. The development of simulation codes combining electrical (RF and DC) guidance fields with gas dynamics will allow for optimized design of new gas cell systems followed by experimental studies. Another objective is the investigation of the use of liquid helium as stopping medium.
