new type cf4 Density Monitors with Low-Cost

In a conventional capacitor, the electric energy is stored statically by charge separation, typically electrons, in an electric field between two electrode plates. The amount of charge stored per unit voltage is essentially a function of the size of the plates, the plate material's properties, the properties of the dielectric material placed between the plates, and the separation distance (i.e ...

  • Development of a New Type Sensor for Micrometeoroid and Space

    Abstract. Several sensor systems are being designed to monitor large (larger than 100 μm) hypervelocity particles in space. Because of the low spatial density of these large particles, the candidate sensor systems must have a large detection area, while the constraints of a space environment deployment require that these systems be low in mass, low in power, robust and low telemetry requirements.
