We study the sidereal and solar time modulation of multi-TeV cosmic rays using the east-west method with Tibet air shower array data taken from November 1999 to December 2008. The statistics are twice the amount used in our previous paper. In this analysis, the amplitude of the observed sidereal time modulation is about 0.1%, and the modulation shows an excess from about 4 to 7 hours and a deficit around 12 hours in local sidereal time. The sidereal time modulation has a weak dependence on the primary energy of the cosmic rays. However, the solar time modulation shows a large energy dependence. We find that the solar time modulation is fairly consistent with the prediction of the Compton-Getting effect for high-energy samples （6.2TeV and 12.0TeV）, but exceeds the prediction for the low-energy sample （4.0TeV）. Such a discrepancy may be due to the solar modulation or the characteristics of the experimental device in the near threshold energy.

In order to observe gamma rays in the 100 TeV energy region, the 4500 m2 underground muon detector array using water Cherenkov technique is constructed, forming the TIBET Ⅲ＋MD hybrid array. Because the showers induced by primary gamma rays contain much fewer muons than those induced by primary hadrons, significant improvement of the gamma ray sensitivity for TIBET Ⅲ＋MD array is expected. In this paper, the design and performance of the MD-A detector with large Tyvek bag is reported.
