Query: Secondary radiation measurements for particle therapy applications:
  Charged secondaries produced by 4He and 12C ion beams in a PMMA target at
  large angle   Measurements performed with the purpose of characterizing the charged
secondary radiation for dose release monitoring in particle therapy are
reported. Charged secondary yields, energy spectra and emission profiles
produced in poly-methyl methacrylate (PMMA) target by 4He and 12C beams of
different therapeutic energies were measured at 60 and 90 degree with respect
to the primary beam direction. The secondary yields of protons produced along
the primary beam path in PMMA target were obtained. The energy spectra of
charged secondaries were obtained from time-of-flight information, whereas the
emission profiles were reconstructed exploiting tracking detector information.
The measured charged secondary yields and emission profiles are in agreement
with the results reported in literature and confirm the feasibility of ion beam
therapy range monitoring using 12C ion beam. The feasibility of range
monitoring using charged secondary particles is also suggested for 4He ion
beam.
