Proton Improvement Plan II (PIP-II) is Fermilab’s plan to upgrade the particle accelerator complex. The linear accelerator (linac) consists of superconductive cavities, which accelerate the particles, and solenoids, needed to steer and to focus the beamline. Cavities and solenoids (also called coldmass assembly) are inserted into a unit called cryomodule (CM). CMs cool and insulate the coldmass assembly from the external environment at room temperature. Superconducting cryomodules use an optical monitoring system to check the alignment of internal components during assembly, testing and operation. This system consists of cameras, known as Boston CCD Angle Monitor “type H” (H-BCAM), and highly reflective targets installed on cavities and solenoids.
