What this contract is for

Unlike conventional multichannel atomic magnetometers that require one vapor cell and one optical system for each sensing channel, the patented Multi-Channel Atomic Magnetometer (MCAM) architecture from Los Alamos National Laboratory replaces many independent atomic magnetometers with a single shared vapor cell and optical system that simultaneously generates multiple independent sensing channels. MCAM is a non-cryogenic multi-channel optical quantum sensor in a single module that captures ultra-faint biomagnetic signals from the brain, heart and other sources with sensitivity approaching that of the cryogenic SQUID-based systems that have defined the field for decades. MCAM delivers that performance at roughly one-tenth the per-channel cost without a drop of liquid helium. The module pairs one large alkali-metal vapor cell with broad pump and probe laser beams read out by a photodiode array, providing 16 independent sensing channels in a single housing, scaling into helmet-style arrays of hundreds of channels, and flexing around the patient rather than forcing the patient into a fixed cryogenic dewar. Together, these attributes more easily allow for magnetoencephalography, magnetocardiography and magnetic-particle imaging while accelerating overall magnetic imaging workflows. Ongoing development is aimed at extending the sensing architecture from the centimeter scale characterized in the current prototype toward micrometer-scale spatial resolution, opening a path into cellular-scale magnetic imaging that current cryogenic and room-temperature arrays cannot address. How it Works The MCAM module operates on the spin-exchange relaxation-free (SERF) regime, in which atomic spins of alkali-metal atoms inside a large, sealed vapor cell are aligned by a circularly polarized b...

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
Check the set-aside listed above and confirm your business actually qualifies for it before you spend time on a proposal. See our guide to set-asides if the category is unfamiliar.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
