The Gamma-ray Transients Monitor
Gamma-ray Transients Monitor (GTM) is the first Space telescope, space astronomical telescope of Taiwan. It is a secondary payload on board Formosat-8B (FS-8B), which is a Remote sensing satellites, remote-sensing satellite developed by Taiwan Space Agency, TASA. The goal of GTM is to track Gamma-ray burst, Gamma Ray Bursts (GRBs) and other bright gamma-ray transients with energies ranging from 50 keV to 2 MeV. GTM is made up of two identical modules on opposite sides of the FS-8B. Each module has four sensor units facing different directions, covering half of the sky. The two modules will then cover the entire sky, including the direction obscured by the Earth. The sensor units consist of a Gadolinium gallium garnet, Gadolinium Aluminum Gallium Garnet (GAGG) (a semiconductor) scintillator array (50 mm x 50 mm x 8 mm) that is readout by Silicon photomultiplier, SiPM with 16 pixel channels. GTM is expected to detect approximately 50 GRBs per year. It is expected to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...
