ABSTRACT
We have developed light and durable mirrors made of CFRP (Carbon Fiber Reinforced Plastics) laminates for the reflector of the new CANGAROO-II 7 m telescope. The reflector has a parabolic shape (F/1.1) with a 30 m2 effective area which consists of 60 small spherical mirrors. The attitude of each mirror can be remotely adjusted by stepping motors. After the first adjustment work, the reflector offers 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. © 2000 American Institute of Physics.
