1. Introduction and Scope

1.1. PIP II Cryogenic Distribution System (CDS)

1.1.1. Fermi National Accelerator Laboratory (FERMILAB) located in Batavia, IL is building a next generation proton accelerator called the Proton Improvement Plan II (PIP-II). The PIP-II accelerator (Linac) design is based on superconducting radio frequency (SRF) technology employed in twenty-three SRF cryomodules. The linac requires cryogenic helium for operation, which is provided by the Cryogenic Distribution System (CDS).

The CDS comprises the equipment needed to feed and return cryogenic helium from a cryogenic plant to the SRF cryomodules. The CDS includes Distribution Valve Box (DVB), Intermediate Transfer Line (ITL), and Tunnel Transfer Line (TTL). Figure 1.1 presents a schematic overview of the PIP-II CDS. The PIP-II CDS feeds individual cryomodules (CM) in the Linac string with the source of the proton beam emanating upstream.

Figure 1.1 Schematic of PIP-II Cryogenic Distribution System

1.2. Cryogenic control valves in the CDS

1.2.1. The following CDS components use cryogenic valves: The Distribution Valve Box (DVB) in the Cryoplant Building, each CDS Bayonet can, 25 total in the accelerator tunnel, and

1 Turn Around Can in the accelerator tunnel.
