The major upgrade of the MAGIC telescopes, Part II: A performance study using observations of the Crab Nebula
Abstrak
MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes located in the Canary island of La Palma, Spain. During summer 2011 and 2012 it underwent a series of upgrades, involving the exchange of the MAGIC-I camera and its trigger system, as well as the upgrade of the readout system of both telescopes. We use observations of the Crab Nebula taken at low and medium zenith angles to assess the key performance parameters of the MAGIC stereo system. For low zenith observations the trigger threshold of the MAGIC telescopes is∼ 50 GeV. The integral sensitivity for sources with Crab Nebula-like spectrum above 220 GeV is (0.66± 0.03)% of Crab Nebula flux in 50 h of observations. The angular re solution at those energies is . 0.07 ◦ , while the energy resolution is 16%. We also re-evaluate the effect of the systematic uncertainty on the data taken with the MAGIC telescopes after the upgrade. We estimate that the systematic uncertainties can be divided in following components: < 15% in energy scale, 11-18% in flux normalization and ±0.15 for the energy spectrum power-law slope.
