TECHNOLOGY LICENSING OPPORTUNITY: Multi-Channel Atomic Magnetometer (MCAM)

Scope

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…
