X-band Continuous Wave Electron Spin Resonance Spectrometer– 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 high speed, Lock-in/Servo system. If no alternate sources are identified, the Government intends to issue a Sole Source Award to Bruker Biospin Corporation; 15 Fortune Drive, Billerica, MA 01821 (UEI: WWMWFMKJLH33) under the authority of FAR 12.102(b) The North American Industry Classification System (NAICS) code for this acquisition is 334516. The Nanoscale Device Characterization Division seeks to acquire a seamlessly integrated, research-grade continuous wave (CW) X-band Electron Spin Resonance (ESR) spectrometer. A primary strategic focus of the division involves utilizing ESR to resolve the chemical and physical nature of atomic-scale defects in materials. This research is critical for identifying and controlling defect entities essential for quantum sensing applications, such as high sensitivity magnetometry. NIST has a need for a visible range continuous wave tunable laser that meets or exceeds the following draft minimum specifications: Contract Line Item Number (CLIN): 0001 Description: continuous wave x-band ESR spectrometer Quantity: One (1) The spectrometer components shall be seamlessly integrated and turnkey. The magnet component shall: Be of a double yoke design. Have ten-inch pole faces. Support L, S, X, and Q band EPR measurements by having a maximum magnetic field strength of at least 14.5 kG with a pole gap greater than 70 mm. Have a magnetic field uniformity of at least 10 mG over the sample area (approximately 1 cm x 1 cm x 2 cm). Be fully compatible with the below described microwave resonators, variable temperature equipment, and other accessories. Be water cooled. Have a suitable water-cooled matched power supply to allow for the above specifications. The microwave excitation/detection component shall: Be an x-band continuous wave microwave bridge with a matched reference arm design with variable attenuation and variable phase. Be seamlessly integrated with other spectrometer components and controllers for frequency, attenuation, reference phase and attenuation settings. All bridge parameters will be software controlled. Permit manual bridge tuning/matching as well as automatic bridge tuning/matching via software and iris motor compatibility. Have an absolute sensitivity of at least 1 x 109 spins per 1 G linewidth. Produce a signal to noise ratio of at least 3000:1 for a weak pitch spin standard. Have a Gunn diode microwave source. Have a working frequency of at least 9.2 GHz to 9.9 GHz. Have a maximum power output of at least 200 mW in a leveled mode. Contain a built-in frequency counter with 1 kHz resolution. Contain a built-in power meter. Contain a microwave attenuator with a range of at least 0 to 60 dB in 1 dB increments with automatic phase correction over the entire range. Include an automatic frequency co…
