BPM located each beam focusing element BPM Measurement Modes There are two modes that need to be supported by the BPM measurements for PIP-II commissioning and operation. The first mode is pulsed beam trajectory is applicable to all BPMs upstream of the MEBT chopper and to all BPMs when the MEBT is off. The second mode is for pulsed beam two trajectories. This occurs for the four BPMs located in the MEBT chopper region and only when the chopper is operational. Table 3.4 the resolution requirements for the BPM system for these two beam modes for beam pulses at least 10 s.

Each BPM is mounted to a quadrupole MEBT doublet or triplet focusing . For a low energy beam the button-type pickups yield good compromise between amplitude and time responses. To test this concept, prototype four-button BPMs have been designed and installed for testing in the PIP-II Injector Test beamline. The left pane of Figure 3.shows the prototype BPM and the right pane shows the BPM mounted to the iron of a MEBT focusing quadrupole magnet. The BPM is 3 maximum diameter 2.7 and a beam aperture 1.12. The prototype BPM is composed of non-magnetic stainless steel and utilizes 20 mm diameter button pickups.
