System and method for operating an ionizer using a combination of amplitude modulation and pulse width modulation to control the plasma temperature and the type of ions needed for analytic equipment. Ion density can be controlled by the repetition rate. The ionizer may utilize a non-radioactive ionization source, and be coupled to a differential mobility spectroscopy (DMS) analyzer.

Nonradioactive ionization source driver

Nanoparticles are coated using thick-film techniques with a catalyst to promote the growth of carbon nanotubes thereon. In one example, alumina nanoparticles are coated with a copper catalyst. Such nanoparticles can be selectively deposited onto a substrate to create a field emission cathode, which can then be utilized within field emission devices.

Catalyst for carbon nanotube growth

A method and apparatus for assembly of small structures is disclosed. The present invention discloses electron beams created from one or more nanotips in an array operated in a field emission mode that can be controlled to apply heat to very well defined spots. The multiple electron beams may be generated and deflected and applied to electron beam heating and welding applications.

Nanospot welder and method

By using a large area cathode, an electron source can be made that can irradiate a large area more uniformly and more efficiently than currently available devices. The electron emitter can be a carbon film cold cathode, a microtip or some other emitter. It can be patterned. The cathode can be assembled with electrodes for scanning the electron source.

Large area electron source

A carbon film having an area of insulating material surrounded by an area of conducing material, and an area of material between the area of insulating material and the area of conducting material having a graded dielectric constant which varies from high to low from the area of insulating material to the area of conducting material. An emission site on the carbon film will emit electrons as a function of time, and as a function of distance across an emission site area.

Field emission material

A triode structure code cathode assembly is produced by depositing a carbon emitter material onto a substrate to form a cathode structure. Then, an insulating layer is deposited onto one side of a mesh foil to form a mesh assembly. This mesh assembly is then mechanically attached to the cathode structure so that the insulating layer on the one side of the mesh assembly is contacting the cathode structure. This entire triode cathode assembly can then be used to produce a field emission display device by including an anode structure.
