Measurement of secondary radiation during ion
beam therapy with the pixel detector Timepix
JINST 6 (2011) C11014
In this contribution we measured the signal behind the head phantom and investigated its
dependence on the beam energy (corresponding to beam range in water 2–30 cm). Furthermore,
the response was measured at four angles between 0 and 90 degrees. At all investigated energies
some signal was registered. Its pattern corresponds to ions. Differences in the total amount of signal
for different beam energies were observed. The time-structure of the signal is correlated with that
of the incoming beam, showing that we register products of prompt processes. Such measurements
are less likely to be influenced by biological washout processes than the signal registered by the
PET technique, coming from decays of beam-induced radioactive nuclei.
