Intense and reproducible Kr K X-rays have been generated via the interaction between 3 TW laser pulse and a micron-sized Kr cluster target. A single photon counting technique with an X-ray CCD was used for measurements of the X-ray energy spectrum in a single shot. At the laser irradiance of 8 
10
W/cm
, the averages and standard deviations of the total X-ray yield and K X-ray yield were equal to 
photons/sr and 
photons/sr, respectively. These results indicate that the X-ray energy spectrum was reproducible at 8 10 W/cm.
