Description
Secondary beams of radioactive nuclei open up new opportunities in nuclear
structure studies and also bring extra requirements for position sensitive
detectors. Individual incident beam particles often need to be tracked, and then
the angles and energies of reaction products need to be recorded with
extraordinarily high efficiency to compensate for low beam currents of less than
100,000 per second. The UK-led TIARA and CHARISSA collaborations have built and
exploited detection systems for charged particles, and TIARA extends also to
include position dependent gamma ray detection with segmented Ge in the EXOGAM
array. The charged particle detection mainly exploits double-sided and resistive Si
strip detectors, but supplemented by CsI scintillators and gas filled drift
chambers. The implementation and use in experiments of CHARISSA and TIARA at the
GANIL laboratory in France will be described, with examples and an indication of
future developments.
