Pioneering space based detector for study of cosmic rays beyond GZK Limit

EPJ Web of Conferences (2013)

B. A. Khrenov M. I. Panasyuk G. Garipov Н. Н. Калмыков П. А. Климов

Space-based detectors for study of extreme energy cosmic rays (EECR) are being prepared as promising new direction of EECR study. Pioneering space device – tracking ultraviolet set up (TUS) is at the last stage of its construction and testing. TUS detector description is presented.

Tracking control of electrostatically actuated micromirror with closed-loop feedback circuit

Electronics Letters (2008)

J.H. Park Tae-Young Chung J. A. Jeon H.S. Kim M. Kim

Presented is a closed-loop feedback control of an electrostatically actuated micromirror to track a moving light source and to stabilise fast the tilting angle. The micromirror has been designed and fabricated with single crystalline silicon. Tracking and tilt-angle stabilisation has been tested using a position-sensing detector and analogue feedback control circuit. Successful tracking of a moving light source was achieved. The feedback control has been also verified to improve the tilt-angle stabilisation time of the micromirror significantly.

Approaching the Spectral Knee in High Energy Cosmic Rays with CREAM

Journal of the Physical Society of Japan (2009)

E. S. Seo H. S. Ahn P. Allison T. Anderson M. G. Bagliesi

The balloon-borne Cosmic Ray Energetics And Mass (CREAM) experiment flew for the third time in Antarctica between 19 December 2007 and 16 January 2008. This ∼29-day flight resulted in an accumulation of almost 100 days of exposure for the CREAM payload. The instrument included double layers of finely segmented Silicon detectors and an imaging Cherenkov Camera for charge measurements. A finely segmented tungsten-scintillator fiber ionization calorimeter was used for energy measurements. Energy spectra of cosmic ray particles for 1 ≤ Z ≤26 were measured at the top of atmosphere with excellent charge and energy resolution. CREAM extends direct measurements of cosmic-ray composition to energies where ground-based air shower measurements are possible, thereby providing calibration for those indirect measurements. The instrument performance during the flight and results from the on-going data analysis are presented. The project status, including preparations for the next flight and results from the beam test carried out at CERN in 2007, are also be reported.
