particle sensor produce in Japan

NASA - Dr. Takashi Oshugi, Particle Physicist and Professor at ...

Takashi Ohsugi is a professor and particle physicist at Hiroshima University, Japan. He joined the Fermi group in 1997. His role was to develop a highly reliable flight silicon microstrip sensor. "At that time no one had experience to utilize 70-80 m2 silicon micro-strip sensors for a tracking detector which requires extremely high quality and reliable sensors," Ohsugi said. "Finally I developed successfully about 100 …

Neutrino detector - Wikipedia

Cherenkov radiation is produced whenever charged particles such as electrons or muons are moving through a given detector medium somewhat faster than the speed of light in that medium. In a Cherenkov detector, a large volume of clear material such as water or ice is surrounded by light-sensitive photomultiplier tubes.

PARTICULATE MATTER IN INJECTIONS TEST

products that produce air or gas bubbles when drawn into the sensor may also require microscopic particle count test-ing. If the viscosity of the preparation to be tested is suffi-ciently high so as to preclude its examination by either test method, a quantitative dilution with an appropriate diluent may be made to decrease viscosity, as necessary, to allow the analysis to be performed. The results obtained in …

Particle arrangement and its application - ScienceDirect

01/12/2000· The final goal of particle arrangement is to produce intelligent materials. However, refinement is necessary to make three-dimensional structures, elimination of noisy particles, more accurate control of particles’ position, etc. We propose an application of the arranging method to an inflammable gas sensor. The detector is an aggregation of n-type semi-conducting particles, such as …

Diesel particulate filter - Wikipedia

Diesel engines produce a variety of particles during combustion of the fuel/air mix due to incomplete combustion. The composition of the particles varies widely dependent upon engine type, age, and the emissions specification that the engine was designed to meet. Two-stroke diesel engines produce more particulate per unit of power than do four-stroke diesel engines, as they burn the fuel-air mix less …

Sensor Principle | RIKEN KEIKI Co.,Ltd.

This gas sensor heats the detectable gas to produce an oxide and measures particles of the oxide using a particle sensor. Maintaining stability over the long term, it exhibits an excellent interference resistance and responsiveness. The particle sensor is based on the same principles as for ionization-based smoke sensors that use radiation.
