Advanced technical developments in support of scientific experiments in space

A technique was developed for preparing solid state, lithium-drifted silicon detectors. Hollow cylindrical detectors were built and tested for possible use as anticoincidence shields to replace conventional plastic scintillators and photomultipliers. A fission cell was developed for the Pioneer F/G instruments and the IMP I subsystem. An electron current detector was developed for Jovian belt measurements of electron flux. A number of circuits and semiconductor devices was also developed.
