Technical Solutions for the MAGIC Telescope

Astroparticle, Particle and Space Physics, Detectors and Medical Physics Applications, 2008
The atmospheric Cherenkov telescope MAGIC for ground-based gamma-ray astronomy is operating since late 2003 on the Canarian island La Palma. The telescope’s 17 m diameter mirror is composed of 964 light weight, square all- aluminum mirrors of 234 m2 total area, which allows to lower the energy thresh- old to a value far beyond that of past generation ...

Cherenkov Telescopes and MAGIC

2019
The first source of very-high-energy (vhe) gamma rays, the Crab nebula, was firmly detected by the Whipple collaboration in the 1980s [1]. Their pioneering instrument and analysis method became the basic concept in the field of Imaging Atmospheric Cherenkov Telescopes (iacts) and paved the way for todays third generation telescopes.

Highlights from the MAGIC telescopes

AIP Conference Proceedings, 2012
The MAGIC telescopes are two Imaging Atmospheric Cherenkov Telescopes (IACTs) located on the Canary island of La Palma. With 17m diameter mirror dishes and ultra-fast electronics, they provide the lowest energy threshold among existing IACTs. Reaching down to 50 GeV in standard trigger mode, it is the only IACT that can close the energy gap between ...

The upgraded MAGIC Cherenkov telescopes

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2014
Abstract The MAGIC Cherenkov telescopes underwent a major upgrade in 2011 and 2012. A new 1039-pixel camera and a larger area digital trigger system were installed in MAGIC-I, making it essentially identical to the newer MAGIC-II telescope. The readout systems of both telescopes were also upgraded, with fully programmable receiver boards and DRS4 ...

Pulsar observations with the MAGIC Telescope

AIP Conference Proceedings, 2007
Pulsars were detected by EGRET up to energies below 20 GeV. Observations at higher energies with ground‐based experiments, including MAGIC, so far failed to detect pulsars, indicating a sharp cutoff of the pulsed emission. Here we present, in particular, the results of the search for very high γ‐ray emission from the pulsar PSR B1951+32.

The FADC readout of the MAGIC telescope

AIP Conference Proceedings, 2000
The MAGIC Telescope will use FADCs to sample the camera pixel signals. This allows to analyze features of the Cherenkov time pulses with ∼1 ns resolution and to minimize data taking deadtime and noise. Here we report on the first tests of a 300 MHz FADC 32-channel unit and on some special solutions for enlarging the signal’s dynamical range.

Commissioning and first tests of the MAGIC telescope

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2004
Major Atmospheric Gamma Imaging Cherenkov telescope is starting its operations with a set of engineering runs to tune the telescope subsystem elements to be ready for the first physics campaign. Many technical improvements have been developed and implemented in several elements of the telescope to reach the lowest energy threshold ever obtained by an ...

Observation of GRBs with the MAGIC Telescope

AIP Conference Proceedings, 2009
After three years since the beginning of operation, the MAGIC telescope could observe several GRB events in the prompt and early afterglow phase. Thanks to its innovative design, the telescope could promptly react to incoming GCN alerts and rapidly slew to the burst coordinates within a typical delay of 50 seconds, performing observations with an ...

Observations of AGNs with the MAGIC Telescope

AIP Conference Proceedings, 2007
MAGIC is the currently world’s largest single dish ground based imaging atmospheric Cherenkov telescope. During its first year of operation, very high energy γ‐ray emission from several active galactic nuclei has been detected. Here we present highlights of the data, including brief discussion about spectral and temporal properties of the emission.
