PCM Telemetry System for 3-MV Superhilac Injector

Data Compression in Pcm Telemetry Systems

The data capacity of aerospace PCM telemetry systems can be greatly improved by the application of data compression techniques, which exploit the redundancy in typical telemetry data. This paper describes the design concept for a compressed PCM (CPCM) telemetry system, and contrasts system design considerations to those involved in development of a conventional PCM system. Simulation results ar...

3-D CALCULATIONS FOR A 4 kA, 3.5 MV, 2.5 MICROSECOND INJECTOR

The DARHT-2 machine under construction at Los Alamos National Laboratory requires a long-pulse (2.5 sec) 2– 4 kA, 3.5 MV, low-emittance electron beam source. The injector is being designed at LBNL and consists of a largearea thermionic cathode mounted atop a vertical column. The 90 bend between the horizontally emitted beam and the column produces dipole and higher-pole fields which must be cor...

PCM/FM aeronautical telemetry in frequency selective multipath interference

Design and Testing of the 2 Mv Heavy Ion Injector for the Fusion Energy Research Program

The Fusion Energy Research Group at the Lawrence Berkeley Laboratory has constructed and tested a pulsed 2 MV injector that produces a driver size beam of potassium ions. This paper will describe the engineering aspects of this development which were generated in a closely coupled effort with the physics staff. The details of the ion source and beam transport physics are covered in another pape...

Telemetry Re-radiation System

Enclosed weapon bays on modern aircraft interfere with prelaunch, Flight Termination System verification during training test launches. Range safety personnel need to verify the functionality of the flight termination system prior to missile launch. The missile telemetry RF is highly attenuated when the aircraft missile bay doors are closed, limiting the range for which the aircraft can fly dur...
