Description
The Advanced Light Source at LBNL is seeking preliminary technical and cost information for a high‑stability monochromator system to serve Beamline 4.3.1. The RFI asks vendors to assess feasibility of double‑multilayer (DMM) and Si(111) configurations, provide budgetary pricing, schedule estimates, and outline engineering approaches for thermal management, angular stability, vacuum integration, and factory acceptance testing. Responses are due 16 Oct 2026 and will inform a future RFP expected in winter‑spring 2027, with system delivery targeted for Dec 2028.
• Evaluate technical feasibility of baseline ~1 % bandwidth DMM at 10 keV & 17 keV and higher‑resolution ≤0.4 % options.
• Assess integration of a Si(111) crystal option and its impact on performance and complexity.
• Provide preliminary cost estimate (≈ $500‑$600 K) and delivery schedule.
• Propose cryo‑cooled multilayer design, thermal‑management, and motion‑feedback concepts to meet 200 nrad RMS angular stability.
• Outline factory acceptance testing (optical, mechanical, thermal, vacuum) and any risks or alternative solutions.
