BL18 In-Vacuum Undulator

The Department of Energy, via SLAC National Accelerator Laboratory, is seeking proposals to design, fabricate, test, and deliver a single BL18 In‑Vacuum Undulator (IVU) for the Stanford Synchrotron Radiation Lightsource (SSRL). The effort includes magnetic design meeting K‑value specifications, mechanical and vacuum system engineering, motion‑control integration, and delivery within 19 months after order receipt to meet an August 2028 installation window. The contract will be a firm‑fixed‑price, best‑value trade‑off award; all proposals must be submitted electronically by 30 Oct 2026. • Scope covers magnetic, mechanical, vacuum, and motion‑control design, manufacturing, testing, and delivery of one IVU (≈ 3.8 m long). • Technical requirements include K_max ≥ 2.20, minimum Cu‑Ni foil width ≥ 65 mm, PT100 temperature sensors, and compliance with Engineering Note M927. • Schedule: baseline 18 months ARO, extended to 19 months ARO; proposal deadline 30 Oct 2026, 5 PM PST; questions due 25 Sep 2026, 5 PM PST.
