Abstract

The CRL 34-m radio telescope at Kashima was completed in 1988. The telescope is equipped with low noise receivers from 1.4 GHz to 44 GHz and is able to observe most of the important astronomical masers in this frequency range. We made an automatic maser survey software and started an H20 maser survey at November 1991 for IRAS color selected objects. Until the end of January 1992, about 930 sources were observed with the rms noise level of 0.1 Jy and about 300 sources were detected.
