G. Marx et al., Status of the SHIPTRAP project: a capture and storage facility for heavy radionuclides from SHIP, HYPER INTER, 132(1-4), 2001, pp. 463-468
The ion trap facility SHIPTRAP is being set up to deliver very clean and co
ol beams of singly-charged recoil ions produced at the SHIP velocity filter
at GSI Darmstadt. SHIPTRAP consists of a gas cell for stopping and thermal
izing high-energy recoil ions from SHIP, an rf ion guide for extraction of
the ions from the gas cell, a linear rf trap for accumulation and bunching
of the ions, and a Penning trap for isobaric purification. The progress in
testing the rf ion guide is reported. A transmission of about 93(5)% was ac
hieved.
