30TH INTERNATIONAL COSMIC RAY CONFERENCE Study of the performance and capability of the new ultra-fast 2 GSample/s FADC data acquisition system of the MAGIC telescope

Tests of a Prototype Multiplexed Fiber-Optic Ultra-fast FADC Data Acquisition System for the MAGIC Telescope

Ground-based Atmospheric Air Cherenkov Telescopes (ACTs) are successfully used to observe very high energy (VHE) gamma rays from celestial objects. The light of the night sky (LONS) is a strong background for these telescopes. The gamma ray pulses being very short, an ultra-fast read-out of an ACT can minimize the influence of the LONS. This allows one to lower the so-called tail cuts of the sh...

Upgrade of the MAGIC Telescope with a Multiplexed Fiber - Optic 2 GSamples / s FADC Data Acquisition system

In February 2007 the MAGIC Air Cherenkov Telescope for gamma ray astronomy was fully upgraded with a fast 2 GSamples/s digitization system. The upgraded readout system uses a novel fiberoptic multiplexing technique. It consists of 10-bit 2 GSamples/s FADCs to digitize 16 channels consecutively and optical fibers to delay the analog signals. A distributed data acquisition system using GBit Ether...

30TH INTERNATIONAL COSMIC RAY CONFERENCE The First Observation with the Fluorescence Detectors of the Telescope Array Ex- periment

The fluorescence measurement is the key in observations of ultra high energy cosmic rays and in determinations of their primary energies in the TA experiment. Almost all fluorescence detectors of TA is in operation from June 2007. Here, we describe the characteristics of the telescopes and the status of the associated systems, and also present preliminary results from the first observation run ...

30TH INTERNATIONAL COSMIC RAY CONFERENCE Data acquisition system of air fluorescence detectors for the Telescope Array exper- iment

The construction of the fluorescence detectors (FDs) of the Telescope Array (TA) experiment have been completed in June 2007, and the stereo observation have been started in June 2007. In this paper, we describe the development of the data acquisition (DAQ) system for the TA FD observations. The DAQ system of each TA FD station is comprised of 16 CPUs: 13 for controls of the FD front-end electr...
