	A dedicated proton injector Linac (pLinac) for the Facility of Antiproton and Ion Research (FAIR) at GSI, Darmstadt, is currently under construction. It will pro-vide a 68 MeV, up to 70 mA proton beam at a duty cycle of max. 35µs / 4 Hz for the SIS18 synchrotron, using the UNILAC transfer beamline. After further acceleration in SIS100, the protons are mainly used for antiproton production at the Antiproton Annihilation Darmstadt (PANDA) experiment. The Linac will operate at 325 MHz and consists of a novel so called ’Ladder’ RFQ type, followed by a chain of CH-cavities, partially coupled by rf-coupling cells. In this paper we present the beam diagnostics system for the pLinac with special emphasis on the Secondary Electron Emission (SEM) Grids and the Beam Position Monitor (BPM) system. We also describe design and status of our diagnostics testbench for stepwise Linac commissioning, which includes an energy spectrometer with associated optical system. The BPMs and SEM grids have been tested with proton and argon beam during several beamtimes in 2022. The results of these experiments are presented.

The test bench will be initially placed after the RFQ with energies of 1.5 MeV, and in later stages moved to other sections of the Normal Con-ducting Linac for operation at 6 and 17 MeV. The Myrrha EMI will be composed by two slit and grid subsystems for measurement of the phase space in the horizontal and vertical directions. For collimating the beam, graphite slits are used, and the beam aperture is measured in the SEM grids placed downstream. Then, the control system performs signal amplification, data acquisition, and motion control, with the different sys-tems integrated in an EPICs IOC. The system, manufactured by ESS-Bilbao and Proac-tive R&D, has been tested on the ESS-Bilbao 45 keV and soon will be integrated in Myrrha facilities. We present the EMI design, with irradiation analysis and emittance reconstruction, and the integration tests results.
