Magnetic Spectrometer is a multi-purpose particle physics experiment that has
been carried to the International Space Station with the launch of Space Shuttle
Endeavour flight STS-134, that took place on 16th of May, 2011. During 8 years
period, AMS has collected approximately 150 billion cosmic-ray data and based
on these data, AMS-02 collaboration has published many papers including proton,
electron, positron and helium particle flux and spectrum in Physical Review
Letters. A series of upgrades to AMS-02 were installed to extend its lifespan
to 2028 between December 2019 and January 2020.
AMS-02
is projected to continue to operate as long as the International Space Station
is maintained in space. Due to a dedicated special link to NASA, the Payload
Operations and Control Center (POCC) is now based at CERN. The METU AMS team
published many papers and contributed to shifts and operations in the POCC, to
data analysis and the listed physics goals, especially that of dark matter
search. After that, the team will focus space radiation environment in order to
analyze helium and heavy ion flux under different parameters in low earth orbit
using the data recorded by AMS-02. Additional to the physics analysis, Machine
Learning algorithms will be investigated in order to increase the efficiencies
of measurements and improve calibrations of AMS-02 subsytems such as the
Transition Radiation Dector(TRD) and Electromagnetic Calorimeter(ECAL). Quantum
Computing methods for particle track reconstruction will be also a point of
intereset as this new method of information processing promisses many benefits
and as these algorithms can be used in particle physics experiments including
AMS-02. These attempts will try the improve the performance of the current
Kalman Filter based algorithms.
