The commissioning of the high power deuterium accelerator of Linear IFMIF Prototype Accelerator, LIPAc, is presently under progress. During the so-called Phase B, the accelerator is operating with a high current pulsed proton and deuteron. The Phase B operation has the goals of fulfilling an exhaustive characterization of equipment and machine parameters in pulsed beam operation up to 5 MeV and 125 mA at Low Duty Cycle. The LIPAc beam diagnostics are aimed to demonstrate at this first stage of the commissioning the correct performance of the accelerator and are used for a complete characterization of the accelerator matching and tuning parameters. The characterization and calibration of beam diagnostics developed are providing relevant feedback of the accelerator operation. Measurements of the centroid position, beam profile, energy, intensity or emittance have been acquired and analyzed. The experimental results gathered have been compared with beam dynamics simulations. In this contribution, an overview of the main results provided by the beam diagnostics during Phase B operation in proton will be shown, together with the status of each instrument.

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.
