480883 Combined Request for Information and Synopsis: Procurement of Ultra-High Vacuum Compatible Hybrid Pixel Detector System for the Booster Polarimeter

The vendor shall design, fabricate, test, and deliver a complete UHV-compatible hybrid pixel detector system for the Booster Polarimeter at BNL. The system must include a 300 µm thick silicon sensor, pixel pitch of 55 µm × 55 µm or smaller, active area of approximately 28 mm × 24 mm, simultaneous per-pixel Time-of-Arrival and Time-over-Threshold readout, support for external trigger and clock inputs, and a heatsink and metallic enclosure. The detector must be vacuum compatible to ≤ 5×10⁻⁹ mbar, use low-outgassing materials, be bakeable to 80°C, and include a ConFlat flange feedthrough (CF100 max, CF63 preferred). Deliverables include a vacuum/outgassing test report, final design approval, hardware delivery, site acceptance test, and documentation package.
