About this file
This document is a Statement of Need from the U.S. Geological Survey's Geology Geophysics Geochemistry Science Center requesting the procurement of a new ATL excimer laser source for its Analyte G2 laser system. The current laser source is over 10 years old, uses outdated technology, and has operational issues that are costly to maintain. The new laser source required is an ATL-300i Gen. 3 extended-life, air-cooled excimer laser with 193 nm (ArF) output and a maximum 300 Hz repetition rate. This will allow the Analyte G2 system to be fully operational in the USGS-LTRACE laboratory and support research for the Earth MRI, Mineral Resource Program, and state geological surveys. The related federal contract opportunity is Solicitation Number 140G0224Q0186, issued by the Department of the Interior U.S. Geological Survey Office of Acquisitions and Grants, for the purchase of the new laser source.

Statement of Need
The U.S. Geological Survey, Geology Geophysics Geochemistry Science Center, requests award of a procurement to for the purchase of a new ATL excimer laser source for the Analyte G2 laser system (unique ID Analyte_115051) for the USGS-LTRACE lab. The awarded contractor shall provide a new ATL-300i Gen. 3 extended-life, air-cooled excimer laser 193 nm (ArF) output, 300 Hz max. rep rate, with solid-state trigger, replaceable cassette-mounted mirrors, and an internal energy detector for stabilized energy output. This new laser source will allow the Analyte G2 laser system to be fully operational in the USGS-LTRACE laboratory. The current ATL laser source is >10 years old and uses outdated thyratron technology that is no longer supported by the manufacturer and is difficult to find replacement parts for. The current laser source also has numerous issues including a small vessel leak, causing short times between gas exchanges; which causes higher operational costs.
The Geology Geophysics Geochemistry Science Center operates a RESOlution-SE laser ablation system (RAI-1098) located in the LTRACE lab, Room G, Building 20, Denver Federal Center. The current LA system (RAI-1098) was installed in January 2023 supports research of high priority to Earth MRI (EMRI), the Mineral Resource Program (MRP) and state geological surveys with funded EMRI initiatives. However, in order to meet the analytical needs of the EMRI work, analytical needs of the G3 and analytical needs of MRP funded projects, a second laser system that is currently in the lab needs to be fully operational. Purchase of this replacement laser source will allow this older laser system to be used for analytical work and method development.
