In the frame of the material research for future fusion reactors, the construction of a simplified version of the IFMIF plant, the so-called DONES (Demo-Oriented Neutron Early Source), is under preparatory phase to allow materials testing with sufficient radiation damage for the new design of DEMO. The DONES accelerator system will deliver a deuteron beam at 40 MeV, 125 mA. The 5 MW beam will impact onto a lithium flow target to form an intense neutron source. One of the most critical tasks of the accelerator is the beam diagnostics along high energy beam transport, especially in the high radiation areas close to the lithium target. This instrumentation is essential to provide the relevant data for ensuring the high availability of the whole accelerator system, the beam characteristics and machine protection. Of outmost importance is the control of the beam characteristics impinging on the lithium curtain. Several challenging diagnostics are being designed and tested for that purpose. This contribution will report the present status of the design of the beam diagnostics, focusing on the high radiation areas of the high energy beam transport line.
