An Optical Re ector System for the CANGAROO-II Telescope
نویسنده
چکیده
We have developed light and durable mirrors made of CFRP (Carbon Fiber Reinforced Plastics) laminates for the re ector of the new CANGAROO-II 7 m telescope. The re ector has a parabolic shape (F/1.1) with a 30 m 2 e ective area which consists of 60 small spherical mirrors. The attitude of each mirror can be remotely adjusted by stepping motors. After the rst adjustment work, the re ector o ers a point image of about 0 .14 (FWHM) on the optic axis. The telescope has been in operation since May 1999 with an energy threshold of 300 GeV.

A new imaging atmospheric Cherenkov telescope with a light-weight re ector has been constructed. Light, robust, and durable mirror facets of containing CFRP (Carbon Fiber Reinforced Plastic) laminates were developed for the telescope. The re ector has a parabolic shape (f/1.1) with a 30 m surface area which consists of sixty spherical mirror facets. The image size of each mirror facet is 0 .08 ...

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. The construction of the fourth telescope was completed in summer 2003, and stereoscopic observations with a local trigger system started in March 2004. Here we report on the status of the system and preliminary results from s...

Preliminary results from CANGAROO-II, a 10 m imaging Cherenkov telescope, in Woomera, South Australia are presented. They include the confirmation of detections of TeV gamma-ray sources we have reported using a 3.8 m telescope, CANGAROO-I. Also the status of the construction of an array of four 10 m telescopes, called CANGAROO-III, is reported. The first telescope of the array was upgraded from...
