CANGAROO III Project
An array of four 10m Cherenkov telescopes in Woomera, Australia
for efficient observation of
celestial gamma-rays in the 100 GeV region
|
 | (Four telescopes at dawn: March 2004) |
By observing Cherenkov images of gamma-ray showers
simultaneously with more than one telescope (stereo mode),
we can determine the direction of gamma-rays accurately
as crossing points of image axes.
Thus we can explore the spatial structure of the gamma-ray
objects as well as discriminating backgroud cosmic-ray showers
more easily.
Moreover, the energy resolution of gamma-rays are improved
knowing the production height of Cherenkov light.
The second, third and fourth telescopes will be installed
in 2001, 2002 and 2003, respectively.
