7 Oct 2011 | | Abstract: | A beam monitor detector based on doped silica and optical fibres has been
designed, constructed and tested, mainly for accelerators used in medical
applications. We conceived a general-purpose device, suitable either for low
currents used in hadrontherapy or for high currents typical for radioisotope
production, as well as for both pulsed and continuous beams. Scintillation
light produced by Ce and Sb doped silica fibres moved across the beam is
measured, giving information on its position, shape and intensity. The coupling
of the doped fibre to an ordinary optical fibre allows the read-out of the
signal far away from the radiation source. Mostly based on commercial
components, the detector is easy to install and operate also in a high
radiation environment due to the absence of any radiation sensitive electronics
located near the fibre. The first successful beam tests triggered new
developments toward the realization of a two-dimensional beam profiler and the
miniaturization of the full device. | | Source: | arXiv, 1110.1583 | | Services: | Forum | Review | PDF | Favorites | |
