Abstract:
An apparatus for detecting molecular signals from a sample, the apparatus comprising:(a) a magnetic shielding cage positioned outside of a cryogenic container; (b) a faraday cage contained within the magnetic shielding cage positioned outside of a cryogenic container; (c) a electromagnetic emission detection coil contained within the faraday cage and positioned near to the sample to detect molecular signals from the sample as combined with white noise; (d) a Super Conducting Quantum Interference Device contained within the faraday cage and cryogenic container, and electrically connected to the electromagnetic emission detection coil; (e) a Super Conducting Quantum Interference Device controller external to the magnetic shielding cage and connected to the Super Conducting Quantum Interference Device; (f) an amplitude adjustable white noise generator exterior to the magnetic shielding cage and producing the white noise signal over multiple frequencies; (g) a noise coil contained within the faraday cage and electrically connected to the white noise generator to output the white noise signal over the multiple frequencies; and (h) a dual trace oscilloscope external to the magnetic shielding cage and electrically connected to the Super Conducting Quantum Interference Device controller and the white noise generator.
