CHIPS R&D Compact Mobile Closed-Cycle Cryostat - Combined Sources Sought/Notice of Intent to Sole Sourceview on SAM.gov

***THIS IS A COMBINED SOURCES SOUGHT NOTICE AND NOTICE OF INTENT TO SOLE SOURCE*** The National Institute of Standards and Technology (NIST) is seeking information from sources that may be capable of providing a large sample stage cryostat. If no alternate sources are identified, the Government intends to issue a Sole Source Award to Attocube Systems GMBH, Eglfinger Weg 2, Haar, 85540, Germany (UEI: GUM6Q15FDTG4) under the authority of FAR 12.102(b) The North American Industry Classification System (NAICS) code for this acquisition is 334516. The National Institute of Standards and Technology (NIST) Quantum Measurement Division (QMD) in the Physical Measurement Laboratory (PML) develops novel spectroscopic measurement techniques to probe key physicochemical properties of low dimensional, advanced quantum materials that will enable future technologies to move past conventional digital computing. Determining the fundamental processes of quasiparticles and related charge migration and phase change phenomena are key aspects of work performed in QMD. As part of the CHIPS Act, researchers from NIST are actively pursuing a comprehensive program in metrology research and development aimed at bolstering the U.S. semiconductor industry. A pivotal aspect of their strategic objectives is outlined in one of the seven Grand Challenges—specifically, Grand Challenge 1. This challenge focuses on enhancing metrology tools and measurement science dedicated to assessing the Purity, Properties, and Provenance of materials, which are critical for advancing the semiconductor sector.
