We present the precision measurement of 2824 daily helium fluxes in cosmic rays from May 20, 2011 to October 29, 2019 rigidity interval 1.71 100 GV based on 7.6×10^{8} nuclei collected with Alpha Magnetic Spectrometer (AMS) aboard International Space Station. The flux and proton ratio exhibit variations multiple timescales. In nearly all time intervals 2014 2018, we observed recurrent a period 27 days. Shorter periods 9 days 13.5 are 2016. strength three periodicities changes rigidity....
We report the properties of sodium (Na) and aluminum (Al) cosmic rays in rigidity range 2.15 GV to 3.0 TV based on 0.46 million 0.51 nuclei collected by Alpha Magnetic Spectrometer experiment International Space Station. found that Na Al, together with nitrogen (N), belong a distinct ray group. In this group, we observe that, similar N flux, both flux Al are well described sums primary component (proportional silicon flux) secondary fluorine flux). The fraction increases for N, Na, fluxes...
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).
Thermal cooling performances of extremely lightweight mechanical carbon fiber support structures with an integrated liquid system for monolithic silicon pixel detectors have been investigated. The high heat removal efficiency using single-phase flow is shown a power density up to 0.5 W/cm2. These solutions provide therefore possibility build detector record radiation length 0.3% per layer, ensuring considerable extensions the physical program investigations quark-gluon plasma in...

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).
