Real time monitoring of hadrontherapy beam intensity and profile is a
critical issue for the optimisation of the dose delivery to the patient
carcinogenic tissue, the patient safety and the operation of the
accelerator complex. For this purpose an innovative beam monitor, based
on the secondary emission of electrons by a nonperturbative, sub-micron
thick Al target placed directly in the extracted beam path, is being
proposed. The secondary electrons, accelerated by an electrostatics
focusing system, are detected by a monolithic silicon position sensitive
sensor, which provides the beam intensity and its position with a
precision of 1 mm at 10 kHz frame rate. The conceptual design and the
engineering study optimised for hadrontherapy, together with the results
of the preliminary tests of the first system prototype, will be
presented.

The isochronous four-sector Cyclotron DC-72 will serve as the basic
facility of the Cyclotron Center of the Slovak Republic in Bratislava. It
will be used for accelerating ion beams of H- to Xe up to energy of
72-2.7 MeV/nucleon.
In the present work a system for external beam diagnostics is presented,
which is intended for on-line acquisition of data on the main parameters
of accelerated beams (current, position, profile, emittance and energy
of the ion beams) to allow effective tuning of the accelerator operation
regime as well as ion beam transport along the transport lines through
the ion optical systems to physical targets and set-ups.
