This is a technical schematic diagram for a cryogenic system designed by Brookhaven National Laboratory's Collider-Accelerator Department. The diagram illustrates a complex gas handling and purification system featuring dual adsorber vessels (V1-A/B), multiple heat exchangers (HX-1/2/3), and associated heating elements. The system manages nitrogen gas supply at 36 PSIG/3.5 bar, liquid nitrogen supply at 3.5 bar, and helium backfill capabilities, with return lines to an RS compressor and gas storage facilities.

The equipment specifications indicate ASME BPVC VIII Division 1 U-stamped components with maximum allowable working pressures of 19 bar and full vacuum capability at 322K, minimum design metal temperature of 78K at 19 bar, and maximum allowable external working pressure of 1.013 bar at 322K. Piping is constructed from stainless steel 304L with various diameters and schedules specified throughout. The system includes tubing specifications (⅜"-T-.049-HE-304L, ½"-SCH5, and 1"-SCH5 configurations), heating elements rated at 75W and 1000W at 120VAC, and a vacuum pump for system operations. The document is marked as export-controlled under U.S. Department of Commerce Export Administration Regulations 15 CFR Parts 730-774 as EARR99 Technology and references compliance verification through WindChill electronic approval systems.
