High precision measurements of reaction products in trap systems like
SHIPTRAP
at GSI require an efficient way of stopping and cooling the energetic ions
prior to
their injection into the trap. This can be achieved with buffer gas cells.
The combination of buffer gas cell and extraction RFQ for the SHIPTRAP
facility
at GSI was designed and characterized at the MLL (Maier-Leibnitz-Labor) in
Garching with
a stopping and extraction efficiency (4-8%) that enabled first successful
high precision
mass measurements at SHIPTRAP.
An improved buffer gas cell is presently set up at the MLL, representing
the
base
for further optimizations of the cell performance also at SHIPTRAP as well
as
for
experiments at the MLLTRAP facility in Garching [1].
