Notice ID Number: NIST-SS26-138
Title: Sources Sought Notice for Pin Well Detector
The purpose of this sources sought notice is to conduct market research and identify potential sources of commercial products/services that satisfy the Government’s anticipated needs.
BACKGROUND
The NIST Radioactivity Group maintains the national standard for radioactivity. The purchase of equipment capable of making 4π gamma-ray measurements provides an alternative method for primary standardization of certain difficult-to-measure radionuclides that decay by electron capture. Electron capture (EC) is a type of radioactive decay that does not produce high-energy beta- or alpha- particles, which are generally easy to detect and count with high efficiency. Instead, the radiations associated with EC are low-energy X rays, medium-energy gamma rays, and/or Auger electrons, which are harder to quantify with the methods currently used by the Radioactivity Group. The Radioactivity Group seeks to acquire a new pin-well detector to complement the existing suite of instruments currently in use in its laboratories and extend its capabilities for 4π gamma-ray measurements, providing an alternate method for the primary standardization of certain difficult-to-measure radionuclides that decay by electron capture. This will enable us to expand our SRM catalog to include several EC nuclides used as radiotracers in medical and environmental research, as well as calibration sources for photon detectors.
NIST is currently seeking a brand name only Mirion Technologies pin well detector system.
The Contractor shall deliver one (1) turnkey pin-well detector system, including an integrated photo-multiplier tube (PMT), cabling, preamps, connections, etc., inclusive of FOB Destination delivery, warranty, technical drawings of the detector, data acquisition and data analysis software, and the line items listed in the Minimum Requirements.
The minimum specifications for the pin well detector system are:
Line Item 0001: Pin well (NaI Detector 3” x 3”)
Description: The system will include a pin well detector, an integrated PMT with high-voltage (HV) supply, preamplifiers, cabling, a Multi-channel analyzer (MCA), an additional backup MCA, and data acquisition and analysis software.
Quantity: One complete system with data acquisition and analysis software
