Descripción
A new series of observation of the Crab Nebula in TeV gamma rays using
an improved camera on the Whipple Observatory 10 m Optical Reflector is
reported. The smaller pixel size results in a lower energy threshold for
gamma-ray detection than that reported in WEA89. The improvement in SNR
compared with the original camera (Cawley et al., 1990) is a factor of
three to four. The results reported here confirm all the salient
features of the detection reported in WEA89, and the significantly
deeper detection now permits the energy spectrum to be derived. It is
also possible to optimize the detection technique so that sources whose
intensity is one-tenth that of the Crab can be detected in 60 hrs of
observation.
