摘要：

TAMA300, an interferometric gravitational-wave detector with a 300 m baseline length, has been developed and operated with sufficient sensitivity to detect gravitational-wave events within our galaxy and sufficient stability for observations. The interferometer was operated stably and continuously for intervals longer than 24 It with a strain noise level of 2 x 10(-21) Hz(-1/2). We carried out nine observation runs, and have obtained over 2700 It of data so far. These data are being analysed to look for gravitational-wave signals. In this paper, we review the design of the TAMA300 interferometer and the observation results, and briefly review the data-analysis activities. In addition, recent efforts to improve the detector are also reported.
