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.

The LIPAc accelerator is 9-MeV, 125-mA CW deuteron accelerator that aims to validate the technology that will be used in the future IFMIF accelerator (40-MeV, 2 x 125-mA CW). LIPAc is presently under beam commissioning of the second acceleration stage (injector and Radio Frequency Quadrupole) at 5 MeV. In this stage two types of BPM’s are used: four stripline-type to control the transverse position and phase at the Medium Energy Beam Transport line (MEBT), and three other stripline-type mainly for the precise measurements of the mean beam energy at the Diagnostics Plate. All the BPM’s have been successfully tested and served to increase the duty cycle and the average power of the beam delivered down to the beam dump. Moreover, the BPM’s were key devices for the transverse beam positioning and longitudinal beam tuning and validation of the RFQ and re-buncher cavities at the MEBT. In this contribution, an overview of the beam position monitors system installation and characterization in the facility will be reported. First tests of the system with the upgraded acquisition electronics for the next phase will be also presented.
