Description
The FAMOUS telescope is a prove-of-concept study for the usage of
silicon based photo sensors (SiPMs) in fluorescence telescopes. Such
telescopes detect the fluorescence light emitted by ultra-high energy
cosmic ray particles impinging on the Earth's atmosphere. Available
instruments, like the fluorescence telescopes of the Pierre Auger Observatory in
Argentina, are using photo multiplier tubes for photon detection. The
FAMOUS camera aims to make use of the advantages of recent developments
in photo detection by SiPM sensors, like increasing the duty cycle due
to the ability to operate SiPMs under bright moon light. Build in a
50 cm-diameter aluminum tube, and employing refractive optics driven by a
Fresnel-lens, a seven-pixel prototype camera has been installed and
developed. First results look very promising. The next stage of the
prototype will be equipped with a 61-pixel camera, a more lightweight
tube, more efficient light concentrators, and a customized and more
stable power supply. The results of the test measurements and the
status of the next stage prototype will be presented.
