Items

  1. a. “Magnetometers”, n.e.s., having a 'sensitivity' lower (better) than 1.0 nT (rms) per square root Hz.
  2. b. “Superconductive” electromagnetic sensors, “components” manufactured from “superconductive” materials and having all the following:
  3. b.1. Designed for operation at temperatures below the “critical temperature” of at least one of their “superconductive” constituents (including Josephson effect devices or “superconductive” quantum interference devices (SQUIDS));
  4. b.2. Designed for sensing electromagnetic field variations at frequencies of 1 KHz or less; and
  5. b.3. Having any of the following characteristics:
  6. b.3.a. Incorporating thin-film SQUIDS with a minimum feature size of less than 2 µm and with associated input and output coupling circuits;
  7. b.3.b. Designed to operate with a magnetic field slew rate exceeding 1 × 10 6 magnetic flux quanta per second;
  8. b.3.c. Designed to function without magnetic shielding in the earth's ambient magnetic field; or
  9. b.3.d. Having a temperature coefficient less (smaller) than 0.1 magnetic flux quantum/K.

Notes

Technical Note: For the purposes of 6A996, 'sensitivity' (noise level) is the root mean square of the device-limited noise floor which is the lowest signal that can be measured.
