The central array of the ARGO detector at the YangBaJing Cosmic Ray Laboratory (4300 m a.s.l., Tibet, P.R. China) has been put into operation for physics runs. It is made of 130 identical sub-units of 12 RPCs each ('cluster') covering a surface of about 5800 m**2 with 92% active area. Signals are picked-up by external electrodes of small size, thus allowing the sampling of EAS with high space ... More

A instrument to image medium energy gamma-rays is being designed for the future NASA Advanced Compton Telescope (ACT) mission. This instrument consists of a gas microwell imaging detector with an active detection volume of approximately 1.6 m x 1.6m x 0.5m which is surrounded by a segmented calorimeter. The use of the gas imager allows for the detection and tracking of the recoil elect ... More

The HAWC (High Altitude Water Cherenkov) observatory is a proposed experiment that combines a very high altitude site with the developed and proven Milagro water Cherenkov technology. HAWC is a 150m x 150m pond of water located above 4100 m over see level with a large field of view and a duty cycle higher than 95%. It observes the relativistic particles and secondary gamma rays in extensive ai ... More

Reliable polarization measurements of photons from Gamma Ray Bursts (GRB) would make the understanding of the GRB phenomenon progress enormously. POLAR is a concept for an instrument that would enable such a measurement. We will report about the first results of the performance of a prototype of this instrument and compare it with Monte-Carlo prediction.

The CANGAROO-III telescope system for very-high-energy gamma-ray astrophysics consists of four 10-m atmospheric Cherenkov telescopes located near Woomera, South Australia. We have been observing southern-sky objects since March 2004. Here we report on the status of the system and some recent results from CANGAROO-III observations.

The 17m diameter MAGIC telescope is currently the largest single dish Cherenkov telescope for gamma ray astronomy. Within the year 2007 it will be upgraded with a second telescope MAGIC-II. Stereo observations will improve the sensitivity of the observatory by a factor of 2 and help to lower the energy threshold. The design, status and expected performance of MAGIC-II will be presented.

VERITAS is an atmospheric Cherenkov telescope array designed to study astrophysical sources of very high energy gamma radiation. Located in southern Arizona, USA, the array consists of four 12-m diameter imaging Cherenkov telescopes. All four telescopes have been deployed at the basecamp of the Whipple Observatory and they became fully operational in early 2007. This paper describes the ... More
