FACT: Towards Robotic Operation of an Imaging Air Cherenkov Telescope

A. Biland, H. Anderhub, Michael Backes, V. Boccone et autres

The First G-APD Cherenkov Telescope (FACT) became operational at La Palma in October 2011. Since summer 2012, due to very smooth and stable operation, it is the first telescope of its kind that is routinely operated from remote, without the need for …

FACT - The first G-APD Cherenkov telescope (first results)

T. Bretz, D. Dorner, Michael Backes, A. Biland et autres

In October 2011, the first air-Cherenkov telescope utilizing Geiger-mode avalanche photodiodes commenced operations. The silicon-based devices display several advantages compared to classical photomultiplier tubes allowing for a more compact camera design of higher reliability, lower power consumption and bias voltage, and better …

FACT: A novel camera for Cherenkov telescopes for ground-based gamma-ray astronomy

Q. Weitzel, H. Anderhub, Michael Backes, A. Biland et autres

The field of gamma-ray astronomy has expanded rapidly during the last decade. In the energy regime from 100 GeV up to several TeV, Imaging Atmospheric Cherenkov Telescopes (IACT) are the most sensitive detectors. Presently all IACTs use photomultiplier tubes for light detection, …

ISOTOPIC COMPOSITION OF LIGHT NUCLEI IN COSMIC RAYS: RESULTS FROM AMS-01

M. Aguilar, J. Alcaraz Maestre, J. Allaby, B. Alpat et autres

The variety of isotopes in cosmic rays allows us to study different aspects of the processes that cosmic rays undergo between the time they are produced and the time of their arrival in the heliosphere. In this paper, we present measurements of …

RELATIVE COMPOSITION AND ENERGY SPECTRA OF LIGHT NUCLEI IN COSMIC RAYS: RESULTS FROM AMS-01

M. Aguilar, J. Alcaraz Maestre, J. Allaby, B. Alpat et autres

Measurement of the chemical and isotopic composition of cosmic rays is essential for the precise understanding of their propagation in the galaxy. While the model parameters are mainly determined using the B/C ratio, the study of extended sets of ratios can provide …
