Discusses the development of bilateral transfer components for the treatment of heterogeneous semantics among document collections in libraries with different descriptive cataloguing styles. Viable solution for an essential portion of the question as to how this goal can be achieved; Theoretical and practical aspects; Current state of the developments; Specific instances for application.

A new design of a cryogenic linear 22-pole ion trap has been constructed and tested. It is essentially a copper housing to which opposite inner walls two electrode sets are attached via sapphire insulators. These stainless steel electrodes are electroformed in one piece to guarantee good heat conduction. Connected to an external coil, they form an LC-circuit of about 19 MHz resonance frequency. This circuit is excited with a rf power supply made of a commercial digital synthesizer followed by a 10 W amplifier. Buffer gas-cooled H2D+ ions have been stored in this trap at a nominal trap temperature of 14 K. Spectroscopy of the ions confirmed that the kinetic (Doppler) temperature is in reasonable agreement with this value. [ABSTRACT FROM AUTHOR]
