This study describes the successful upgrade of a mechanically pumped CO$_2$
two-phase cooling system in space by designing a new pump module for the Alpha Magnetic Spectrometer-02 on the International Space Station. Key factors for mission success are emphasized, including achieving high coolant filling accuracy within 10% of the target and maintaining system stability within ±1

The role of the NA62 RICH in the $BR(K^+ \to \pi^+ \nu \bar\nu)$ measurement

The NA62 experiment aims to measure the $BR$($K^+$ $\rightarrow$ $\pi^+$ $v$ $\overline{v}$) with a 10% precision. One of the main backgrounds comes from the decay $K^+$ $\rightarrow$ $\mu^+$ $v$ , therefore a highly powerful pion/muon separation is needed. [...]

The Ring Imaging Cherenkov detector of the NA62 experiment at the CERN SPS is a key element of particle identification in the NA62 experimental strategy. The detector fulfills different conditions: to distinguish pions from muons with a muon rejection factor of O(10$^2$) in the NA62 momentum range of operation, between 15 and 35 GeV/c; to measure particle arrival time in the decay region with a precision better than 100 ps; to provide fast signals and reference time to the NA62 trigger system.

NA62 is the last generation kaon experiment at CERN SPS aiming to study the decay K$^+$ $\rightarrow\pi^+ \nu \bar{\nu }$. The goal of the experiment is to measure the decay branching ratio, $O$ (10$^{-10}$) , with 10% precision collecting about 100 K$^+$ $\rightarrow\pi^+ \nu \bar{\nu }$ events in three years of data taking and assuming a 10% signal acceptance.

The beam and detector of the NA62 experiment at CERN
/ NA62 Collaboration
NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays. Such measurements, like the branching fraction of the $K^{+} \rightarrow \pi^{+} \nu \bar\nu$ decay, have the potential to bring significant insights into new physics processes when comparison is made with precise theoretical predictions.

/AMS
A precise measurement of the proton flux in primary cosmic rays with rigidity (momentum/charge) from 1 GV to 1.8 TV is presented based on 300 million events. Knowledge of the rigidity dependence of the proton flux is important in understanding the origin, acceleration, and propagation of cosmic rays. [...]
