Performing ultra high precision photometry

The Ames Research Center is responsible for the ground system development, mission operations since Decemberand scientific data analysis. The initial planned lifetime was 3. Initially, inthe mission was expected to be extended until[16] but on July 14,one of the spacecraft's four reaction wheels used for pointing the spacecraft stopped turning, and completing the mission would only be possible if all other reaction wheels remained reliable.

The photograph shows the standard blackbody system for the calibration of ear thermometers developed by MD. It is a transportable high-accuracy standard blackbody system that was supplied to overseas institutes such as those in Singapore, and its use contributed effectively to prevention of a SARS epidemic in Asian countries.

It is necessary to utilize a space in which the minimum possible scattering and reflection of waves from the surroundings are ensured to enable accurate measurement of the strengths of electric and magnetic fields and standard antennas. An open-area test site is used as an outdoor measurement field for the frequencies from 30 MHz to 1 GHz.

An electromagnetic anechoic chamber 24 m x 15 m x 9 m with surrounding walls, a ceiling and a floor constructed as close to nonreflecting as possible, is used as an indoor measurement field for frequencies of up to 40 GHz. These spectra have been collected since the s and the data have been made available on the internet freely since They are frequently accessed globally.

The instrument developed at MIJ measures flatness by comparing a specimen with a precisely polished reference optical flat using Fizeau interferometry. It has a mm-diameter measurement area which covers a inch silicon wafer. National standards for gamma-ray are established using the graphite cavity ionization chamber shown in the photograph.

The values of personal monitors used in the vicinity of facilities utilizing ionizing radiation are calibrated on the basis of the reference standards of MIJ.

To calibrate high-accuracy rotary encoders, MIJ succeeded in developing a rotary encoder angle self-calibration system with the world's highest accuracy, enabling calibration at an accuracy of approximately 0.

A film face of a transparent substrate side is heated by a pico-second laser pulse. Heat generated by the pump laser pulse diffuses towards the front surface of the thin film.

The temperature change on the front surface opposite to the heated area is measured by the reflected intensity of probe pico-second laser pulse. The heat diffusion across molybdenum thin films with thickness of 75,and nm has been observed successfully for the first time in the world.

Kepler is a retired space observatory launched by NASA to discover Earth-size planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched on March 7, , into an Earth-trailing heliocentric principal investigator was William J. nine years of operation, the telescope's reaction control system fuel was depleted, and NASA announced.

Based on this technique, MIJ are now developing the thin film thermal diffusivity standard and reference thin films for thermal diffusivity measurements. Common Measures for Chemical Analysis Fig. As methods considered to be potentially the primary methods of measurement in realizing traceability to SI, titrimetry, gravimetric analysis and coulometric titration play major roles, particularly in the field of inorganic analysis.

For example, it is possible to directly compare moles by applying EDTA chelatometric titration to many inorganic standard solutions.

Gravimetric analysis is ultimately traceable to Prototype Kilogram.

Coulometric titration is based on Faraday's law; it is used to realize a mole using current and time without any reference material.The CHaracterising ExOPlanet Satellite (CHEOPS) is a joint ESA-Switzerland space mission (expected to launch in ) dedicated to search for exoplanet transits by means of ultra-high precision photometry.
