In outer space down to the altitudes routinely flown by larger aircrafts, radiation can pose serious issues for microelectronics circuits. The 88-Inch Cyclotron at Lawrence Berkeley National ...Laboratory is a sector-focused cyclotron and home of the Berkeley Accelerator Space Effects Facility, where the effects of energetic particles on sensitive microelectronics are studied with the goal of designing electronic systems for the space community. This paper describes the flexibility of the facility and its capabilities for testing the bombardment of electronics by heavy ions, light ions, and neutrons. Experimental capabilities for the generation of neutron beams from deuteron breakups and radiation testing of carbon nanotube field effect transistor will be discussed.
Results of optimization studies regarding the composition of silicone rubber films suitable for preparing miniaturized solid-state ion-selective sensors are presented. Using conventional macro ...ion-selective electrodes (ISEs) it was shown that the addition of more lipophilic ionic additives and small amounts of an appropriate plasticizer to the silicone matrix achieved optimal electroanalytical performance. The incorporation of these components into the membrane along with the required ionophore can, however, influence membrane curing time and adhesion of the film to silicon nitride surfaces. Solid-state sensors with optimized silicone membrane compositions exhibit theoretical and reproducible electrochemical performance.
