Operational status of TAMA300 with the seismic attenuation system (SAS) [PDF]
, 2008 TAMA300 has been upgraded to improve the sensitivity at low frequencies after the last observation run in 2004. To avoid the noise caused by seismic activities, we installed a new seismic isolation system —- the TAMA seismic attenuation system (SAS ...
