Abstract

The Proton Improvement Plan, Stage Two (PIP-II), is a program of upgrades proposed for the Fermilab injection complex, the central part of which is an 800 MeV, 2 mA CW-compatible SRF linac. A prototype of the PIP-II linac front-end called the PIP-II Injector Test (PIP2IT) is being built at Fermilab. As of now, a 15 mA DC, 30 keV H[Formula: see text] ion source, a 2 m long Low Energy Beam Transport (LEBT), a 2.1 MeV CW Radio-Frequency Quadrupole (RFQ), followed by a 10 m Medium Energy Beam Transport (MEBT) have been installed and tested. A Fast Faraday Cup (FFC) installed in the MEBT measures the length of a beamlet cut out of the bunch by a small-size entrance hole of the FFC. The information about the bunch length measured at various settings allows for the reconstruction of the longitudinal beam dynamics and optimization of injection into the first cryomodule.
