A gridded planar probe has been developed to measure plasma parameters in a dc magnetron sputtering discharge. The gridded probe essentially consists of an outer grid in conjunction with the inner collector forming a stacked electrode configuration. The grid space needs to be less than the Debye length in order to assume the planar plasma-sheath structure. In addition, the grid-to-collector...

Ultra-high vacuum is a key requirement that determines electron beam quality and lifetime for an electron accelerator complex. In operation of the Siam Photon Source (SPS), pressure distribution of storage ring has been monitored using a series of Cold Cathode Gauges (CCGs) installed in proximity to the vacuum pumps around the ring. Pressure between the CCGs was calculated based on the...

The common-envelope process is known as one of the complicated phases in binary evolution. A lot of efforts have been dedicated to study this common-envelope stage, but the many questions related to this process are yet to be answered. If one binary survives the common-envelope, the binary will emerge as a white dwarf accompanied by low-mass main sequence star in close orbit, or often referred...
