MEGHA
A Multi-Element Gas Hybrid Array
Designed and constructed in the UK by a collaboration from the Universities of Birmingham, Oxford, Staffordshire, Surrey and York and the CLRC Daresbury Laboratory
Installed at the 14UD accelerator at the Department of Nuclear Physics, RSPhysSE, ANU, Canberra, Australia
Its purpose is to investigate multi-particle breakup reactions to probe the cluster structure of nuclei and to investigate the properties of exotic nuclei
The MEGHA system is an array of detector telescopes for detecting heavy ions and an array of strip detectors for detecting light ions.
Each telescope consists of:
a gas ionisation telescope
to measure D
E for heavy ions.
a two-dimensional position sensitive
silicon detector to give position and energy for heavy ions and
position and D
E for light ions.
CsI scintillation detector coupled
to a photodiode to give energy of light ions.
Each strip detector consists of 16 position sensitive strips, each 3 x 50mm.
The full MEGHA system consists of 44 telescopes mounted in 5 modules, and up to 12 strip detectors.
Dedicated electronics and data acquisition system provides 320 energy channels and 320 timing channels.
The MEGHA array is now fully operational. Experiments run to date include:
studies of clustering in nuclei.
the use of angular
correlations to distinguish reaction mechanisms.
orbiting reactions
studies of the structure
of halo nuclei.
