About this file
This document is Attachment D - DWG 2551m0003 Rev 2 5-29-2024.pdf, which provides detailed technical specifications for the 18 MM Button BPM (Beam Position Monitor) assembly to be used in the Hadron Storage Ring of the Electron-Ion Collider (EIC) project.
The key details include: the material requirements (stainless steel housing, solid copper or copper-plated button), fabrication and assembly specifications (laser engraving, UHV compatibility, cryogenic and high-temperature operation, 50-ohm impedance, copper plating), and quality requirements (helium leak test, BSA approvals). The drawing contains multiple views, details, and notes to fully define the design and manufacturing parameters for this component. This attachment is referenced in the related federal contract opportunity for the EIC HSR BPM Button Assembly, which is a solicitation for the design and fabrication of up to 1,390 of these button assemblies across multiple subcontracts.
