 (CANGAROO Collaboration) 

CANGAROO Collaboration has observed a number of objects such as pulsars, 
supernova remnants and active galactic nuclei to detect TeV gamma rays with 
a ground­based telescope of imaging Ÿ 
Cerenkov technique which is located in 
South Australia. Several galactic sources of synchrotron X­rays are found to 
be TeV gamma ray emitter of inverse Compton radiation to put constraint on 
the energy of progenitor electrons and the strength of magnetic field in pulsar 
nebula and supernova remnant. A summary of TeV gamma ray observation by 
CANGAROO is presented as well as the current status and efforts of improving 
detection sensitivity of TeV gamma rays.
