  The report deals with the construction of the carbon beam transport line for biomedical research at the Nuclotron accelerator complex, JINR, Dubna. We have studied the scheme and modes of magneto-optical elements of the channel. Used electronics described. We are discussed the compilation and realization of the plan of treating a tumor located at a depth up to 30 cm. Choice of beam scanning schemes and their optimization are shown.

  A monitoring system online controls a therapeutic proton beam by measuring a secondary neutron radiation from the beam losses. The system consists of neutron detectors in the transport path passage from Linac to the facility of proton therapy and terminal controller connected to the computer. The neutron detectors measure a level of the secondary neutron radiation in real time along of the transport channel, near the formative elements. The system of the neutron detectors registers temporal variations of the beam intensity in local areas transport medical channel. These changes arise are due to changes in operating mode of the channels or instability of the elements forming the beam. The monitoring system allows to determine a intensity and temporal structure of the therapeutic beam and to detect mode and instability of the formative elements.
