4. Statutory Authority. 10 USC 2304(c)(1) Only one responsible source and no other supplies or services will satisfy the agency requirement.

5. Justification or Authority for Action. Toptica is the only known manufacturer of a fiber coupled, rack mount laser system for laser cooling and trapping barium ions. This laser system will satisfy the requirements of the trapped ion lab’s experiments and size weight and power reduction goals. This system has been shown in the literature to work well for this experiment. This system is unique to Toptica and they are the only known source of the system described in section 3. If this system is not procured from Toptica, there will be a halt of future experiments of the lab and will cause the inability to meet yearly program milestones. The existing equipment to which this purchase is a part of, is valued at more than and was built using years of work.

6. Efforts Made to Ensure Offers are Solicited from as many Sources as

Practicable.

A Notice of Proposed Contract Action was synopsized as a pre-solicitation notice on BetaSAM (www.Beta.SAM.gov) between 05 May 2020 and 20 May 2020, no responses were received.

7. The Contracting Officer determines that the anticipated cost to the

Government will be fair and reasonable based on a complete analysis of the contractor’s prices in accordance with FAR 15.404-1(b)(2)(vii)Other than certified cost or pricing data was analyzed and FAR 13.106-3(a)(2)(iii)
