Guidance Systems

A second important need for some guidance system lies in stray electric fields. Clearly, a sufficiently large potential arranged transversely to an ion beam can serve to deflect ions away from the intended direction. Such stray fields can be produced easily by sharp edges or points on the inside of a mass spectrometer and even more so in an ion guide itself. Considerable care is needed in the construction and design of mass spectrometers to reduce these effects to a minimum. 

The octopole configuration is similar to the quadrupole and hexapole in affording a good ion guidance system in its all-RF mode. The poles are connected in two pairs of four nonadjacent rods, and each pair is connected to an RF voltage supply, 180° out of phase with each other. The octopole is even more efficient than the hexapole as an ion guide.

As a light, strong metal, beryllium holds considerable promise as a useful engineering material, but because of an inherent directional brittleness, a really significant commercial use, e.g. in the aircraft industry, has not proved possible. It has been used to a limited extent in aerospace applications, and it was employed as heat shields for the Project Mercury space capsule. It has also found use in precision guidance systems when fairly pure environmental conditions can be assured.

A modified version of this semiactive technique has the transmitter located in the missile and the receiver of the reflected energy at some remote point. Computation of the desired flight path takes place at a remote point and suitable commands are sent to the missile. This system is known as a quasi-active homing guidance system...

The name is used both for the monomer and polymers made horn it. The polymers are usually clear oils at RT and non cracking solids at —65°F(—54°C). The typical fluoro-carhons are chemically inert, thermally stable, and nonflammable. The monomer can be prepd similarly to CFE from tribromotiifluoroethane and zinc. BFE polymers are used as flotation fluids for gyros and accelerometers used in inertial guidance systems. Can also be used as CFE (chlorotrifluoroethylene) polymers, but are more expensive Refs 1) Beil 1, 189 2) CondChemDict...
