Four different types of commercial JFET input operational amplifiers were irradiated with ionizing radiation under a variety of test conditions. All experienced significant increases in input offset voltage (V/sub os/) for the worst-case irradiation bias. Microprobe measurement of the electrical characteristics of the de-coupled input JFETs on both non-irradiated and irradiated circuits demonstrates that the increase in V/sub os/ is a result of the mismatch of the pinchoff voltage of the degraded JFETs.

This paper presents the effects of synchrotron radiation (i.e. X-rays of high energies), combined with the associated parasitic radiation, on equipment of a third generation Synchrotron Light Source after seven years of X-ray beam delivery. Dose measurement data is associated with the observed radiation damage. The future ID6 beamline experiment is described. This irradiation bench will be dedicated to test the behaviour of standard materials (mainly electric cables and cooling hoses) with hard X-rays. The aim is to identify more radio-resistant components to replace the damaged ones. Various ways to reduce the electron beam losses are also presented, with their associated effects.

The Standard Radiation Environment Monitor (SREM) was designed in a cooperation between ESA-ESTEC, PSI and Contraves Space-the manufacturer. The monitor detects cosmic particles using 3 direction sensitive Si detectors. Total dose measurement is performed with internal and external RADFETs located at selected positions on the satellite. Their sensitivity towards protons and gammas was characterised for various energies, dose rates and exposure geometry.

We measured the gamma radiation-induced attenuation in custom made phosphorous and germanium-phosphorous doped fibres at different temperatures for doses up to 360 Gy. Two different components in the recovery kinetics were evidenced. For dosimetry, the phosphorous doped fibre may be interrogated at a single wavelength within an optimal wavelength region of 1200 nm to 1400 nm. Alternatively, we studied the possibility of reconstructing the dose using attenuation data at different wavelengths. The necessary condition for this to work is that enough independent information can be obtained from the attenuation data with respect to the disturbing parameters like temperature, varying dose-rates and recovery. This was only the case for the phosphorous doped fibre and low total doses.

The Cosmic Radiation Environment Dosimetry experiment is providing data on particle fluxes and linear energy transfer spectra for inner belt protons, cosmic rays and solar particles in order to correlate with device behaviour in the MPTB experiments and to provide tests of environment models. Particle fluxes are related to geomagnetic co-ordinates in order to explain the observed time variations around the orbit and the differences between odd and even orbits. Cosmic-ray fluxes are slowly decreasing as solar maximum is approached. Outer-belt electrons show large variations and are particularly enhanced during late August to November 1998. Several solar particle events have been observed. Integral linear energy transfer (LET) spectra for these show both lower intensities and a lack of enhancement at high values of LET when compared with the October 1989 event which is commonly used as a worst case.

Single-Event Upset (SEU) immunity for commercial devices were evaluated by irradiation tests using high-energy heavy ions. We show test results and describe the relationship between observed SEU rate and structures/fabrication processes. In this experiment, single-ion Multiple-Bit Upsets (MBUs) in 4 Mbit SRAM, 16 Mbit DRAM and 64 Mbit DRAM were observed. These MBUs were also discussed.

At the CERN Proton Synchrotron (PS), the 24 GeV/c primary beam allows the operation of two new irradiation facilities. One is using directly the primary proton beam and the other one is using secondary particles (mainly /spl sim/1 MeV neutrons) produced in a cavity after a beam stopper. For both facilities, samples to be irradiated are brought to the irradiation positions by means of automatic shuttles. Designs, Monte Carlo simulations of particle spectra and background are presented as well as the performance achieved.
