Abstract
An example smoke detector includes (i) a chamber, wherein gas is disposed in an inner space of the chamber; (ii) an electrode disposed within the chamber; (iii) a magnet configured to generate a magnetic field in the inner space of the chamber; and (iv) a radioactive source generating alpha particles within the inner space of the chamber.
Claims20
A smoke detector comprising:
- a chamber;
- a first electrode disposed within the chamber;
- a magnet disposed within the chamber opposite the first electrode, wherein the magnet is electrically-conductive and is configured as a second electrode, wherein gas is disposed in an inner space of the chamber between the first electrode and the magnet, and wherein the magnet is configured to generate a magnetic field in the inner space of the chamber;
- and
- a radioactive source generating alpha particles within the inner space of the chamber.

A smoke detector comprising:
- a chamber;
- a first electrode disposed within the chamber;
- a second electrode disposed within the chamber opposite the first electrode, wherein gas is disposed within the chamber between the first electrode and the second electrode;
- a radioactive source mounted to the first electrode, wherein the radioactive source is configured to emit alpha particles in the gas disposed between the first electrode and the second electrode;
- and
- a magnet disposed in the smoke detector and coupled to an exterior surface of the chamber adjacent to the second electrode, wherein the magnet generates a magnetic field having magnetic flux lines passing through the gas between the first electrode and the second electrode.

A smoke detector comprising:
- a chamber;
- a first electrode disposed within the chamber;
- a second electrode disposed within the chamber, wherein gas is disposed in an inner space of the chamber between the first electrode and the second electrode;
- a radioactive source emitting alpha particles in the gas disposed between the first electrode and the second electrode;
- a first magnet that is ring-shaped and mounted to an exterior surface of the chamber at a first side of the chamber;
- and
- a second magnet that is ring-shaped and mounted to the exterior surface of the chamber at a second side of the chamber opposite the first side thereof, wherein the first magnet and the second magnet cooperate to generate a magnetic field having magnetic flux lines passing through the gas disposed between the first electrode and the second electrode.
