The hitrap and shiptrap projects at gsi - technology and use of traps

Objective



Research objectives and content
By the use of traps now available, exotic and rare particles like highly charged ions can be confined, cooled and observed over long periods of time. The use of these devices in physics for spectroscopy is until now restricted to a few places in Europe. It would be interesting to transfer advanced expertise in the utilisation of this novel technique to other European places. Scientists from GANIL at Caen and the University of Caen, where I have obtained my Ph.D., would like to realise in close collaboration with the GSI team a Penning trap system for the SPIRAL project. In this respect, it is thus major important to acquire experience on the two traps (the HITRAP and SHIPTRAP projects) which must be tested and set up at GSI. The first one, the HITRAP, is planned for g-factor measurements of bound electrons in hydrogen-like ions and for mass measurements of bare and few-electron highly charged ions (MCI) up to U92+ SHIPTRAP is going to store exotic and superheavy elements which can be produced and effectively separated in SHIP facility, for precise measurements of their masses and lifetimes. With the GSI team expert in Penning trap techniques, young researchers can train in highly advanced technologies.
Training content (objective, benefit and expected impact)
These two projects offer a great opportunity to learn both technology and use of traps and in particular to approach all the problems concerning the adjustment and the modifications of facilities at GSI: the cooling of HCI the ion optics for the transfer of HCI from an ion source into an ion trap the vacuum the temporal stability of the magnetic field the technology of superconducting magnets The use of traps requires knowledge about atomic physics with highly charged ions.
