The Alpha Magnetic Spectrometer AMS-02 [1]-[4] is an astro particle physics experiment running on the International Space Station (ISS; see Figure 1) since May 19, 2011. Its missions include search for antimatter and identification of nature dark matter. AMS silicon tracker only subdetector inside permanent magnet that can detect charge a moving to distinguish anti-particle from (see Table 1 nomenclature).
Abstract：The inlet oil temperature of high-speed and light-loaded turbocharger system changes dynamically under the operating conditions long period variables speed, thus changing vibration characteristics rotor even leadi ng to nonlinear accidents.High-speed light-load for a certain type gasoline engine is studied.The variation minimum thickness eccentricity ratios inner film in floating ring bearing with different te mperature analyzed.The dynamic finite element model rotor-floating...
Summary Reliable low frequency content and phase alignment are critical for broadband seismic inversion the prediction of reservoir properties. However, currently there is a lack tools ultra-low (less than 5 Hz) quality assessment. A focusing metric in impedance domain proposed to assess alignment. The method has been applied on real dataset assessment residual correction process conclusion validated by using well information.
The ring‐speed ratio is a comprehensive dynamic index of floating ring bearing structure and operating parameters, which directly affects the behavior turbocharger rotor system. cross stiffness work oil film force are analyzed. influence change on vibration response was studied. finite element model rotor‐floating system constructed; its parameters verified through measured critical speed. Newmark integral method used to analyze nonlinear transient response. results show that when between...
To provide a stable thermal environment for the AMS-Tracker, control system based on mechanically pumped CO2 two-phase loops was developed. It has been operating reliably in space since May 19, 2011. In this article, we summarize design, construction, tests, and performance of AMS-Tracker (AMS-TTCS).
