Xspress 3X Mk2 Readout Systems (8 and 13 Channels)

Argonne National Laboratory, under the Department of Energy Office of Science, is soliciting quotes for Xspress 3X Mk2 8 and 13-channel readout systems designed for silicon drift detectors (SDD) or high-purity germanium (HPGe) detectors, or domestically manufactured technically equivalent solutions. The procurement requires vendors to submit a completed ANL-70 Request for Quotation, ANL-70B Representations and Certifications form, published price lists, and supporting documentation by 12:00 pm CST on January 21, 2026. Key technical requirements include a full-spectrum readout rate exceeding 100 kHz, deadtime less than 10 percent, energy resolution under 200 eV, timing resolution under 50 nanoseconds, EPICS compatibility, and list mode event tracking capabilities. The readout systems must meet national testing laboratory standards and electrical safety regulations, with a 12-month warranty following installation. The solicitation does not specify explicit evaluation criteria beyond technical compliance with the Statement of Work requirements, and vendors should direct questions to the Contracting Officer.

This procurement carries no set-aside designation and includes no identified incumbent contractors. While specific award values or budget ranges are not disclosed in the solicitation documents, the procurement is classified under NAICS 423490 (Other Professional Equipment and Supplies Merchant Wholesalers) with PSC 6640 (Laboratory Equipment and Supplies). The contract requires a 9-month delivery timeline following award, with installation scheduled at the Advanced Photon Source 19-ID beamline end station. Pricing terms are net 30 days with delivery specified as DAP (Delivered at Place) to Lemont, Illinois, where the equipment will be installed and supported by vendor technical assistance during the on-site implementation phase.
