Linear IFMIF Prototype Accelerator (LIPAc) is a hadron LINAC developed and operated under the EU-JA collaboration, for validating technologies to accelerate a 9 MeV deuteron beam at CW, and high beam current (125 mA). LIPAc is presently in the commissioning phase namely B+, where the beam line is fully constructed by replacing the superconducting LINAC section between medium and high energy beam transport lines with an intermediate transport line for 5 MeV deuteron beam from RFQ. To compare different measurement method non-interceptive and also interceptive diagnostics, it is important to operate them at low duty cycle. Also, changes in beam properties can be traced by comparing the BPM data. Phase-B+ operation is useful to validate the beam transport codes, by using BPM measurement. This report presents the progress of the BPM with the results of the low duty cycle stage of Phase-B+ in 2021, and about the studies related to RF noise floor of the BPM signals. |
