We describe an experimental arrangement for the investigation of b+-decay
end-point energies based on the use of a surface barrier silicon detector for b-particles and two Ge(HP) detectors for photons in a three-axes
detection geometry. The system was tested using a 58Co source. The positron
end-point energy determined by the Fermi plot analysis of the experimental data was found
to be in good agreement with the values quoted in the literature.
