	Funding: AIC10-D-000518 and AIC-D-2011-0673. Beam Position Monitors (BPM) are essential elements in the instrumentation for the beam control in hadron therapy accelerators. The measurement of the beam position become more important at the secondary transport lines towards the patient room where this parameter must be completely determined. In this paper we describe the design, construction, read-out electronics and first calibration tests of a new type of BPM based on four scintillating fibers coupled to four photodiodes to detect the light produced by the fibers when intercepting the beam tails. The prototype will serve to evaluate the different design options in the mechanical and the read-out electronics implementation as well as to define the best processing method to get the beam position.

Beam Position Monitors (BPM) are essential elements in the instrumentation for the beam control in hadron therapy accelerators. The measurement of the beam position become more important at the secondary transport lines towards the patient room where this parameter must be completely determined.
