Isobaric Separation |
|
|
Due to the nature of the nuclear reactions which produce the RIBs and
the proximity of stable target material elements to the mass of the radioactive
ion, the likelihood of producing a beam containing several species with
nearly identical m/q values is quite high. In order to achieve well defined
experimental conditions by delivering a 'pure' beam to the target, a high
resolution second stage mass separator is utilized to filter out these
'isobars'. The system has been designed to achieve a resolving power of
m/Δm~20,000 with a high quality beam. In practice,
some what lower resolving powers are realized due to energy widths which
are larger than ideal
ΔE>10 eV. A GIOS output
of the optics of this separator is shown here.
