  Currently, radiobiology experiments using heavy ions at GANIL(Grand
Accelerateur National d Ions Lourds) are conducted under the supervision of the
CIMAP (Center for research on Ions, MAterials and Photonics). In this context,
a new beam monitoring equipment named DOSION has been developed. It allows to
perform measurements of accurate fluence and dose maps in near real time for
each biological sample irradiated. In this paper, we present the detection
system, its design, performances, calibration protocol and measurements
performed during radiobiology experiments. This setup is currently available
for any radiobiology experiments if one wishes to correlate one s own sample
analysis to state of the art dosimetric references.
