Cosmic ray interaction with detectors of the Planck satellite for the measurement of the cosmic microwave background radiation polarization

Hoang Duc THUONG (AstroParticles and Cosmology - APC)

The Planck satellite of ESA was launched 2009 from Kourou France Guyana. It measure temperature and polarization anisotropies of the cosmic microwave background radiation (CMB).The Planck observe the CMB by two main instruments Low Frequency Instrument and High Frequency Instrument. The work focus on the study of the cosmic rays on the Planck High Frequency Instrument. The high energy particle hitting to the silicon die of polarization sensitive bolometers (PSB) and spider wed bolometers (SWB) deposit energy and produce the long glitches on the scientific data. Therefore the modeling, analysis and simulation are play a vital role to understand and characterize of the long glitches. This understanding allows to better remove the impact of the long glitches on polarization sensitive bolometers data.
