MiniGRAIL
Gravitational Radiation Antenna In Leiden
Kamerlingh Onnes Laboratory, Leiden University, The Netherlands
The 7th cryogenic run of MiniGRAIL started at 6/11/2004.
Click here for an overview.
Last update: December 6 - 2004
The MiniGRAIL detector is a cryogenic 68 cm diameter spherical
gravitational wave antenna made of CuAl(6%) alloy with a mass of 1400
Kg, a resonance frequency of 2.9 kHz and a bandwidth around 230 Hz,
possibly higher. The quantum-limited strain sensitivity dL/L would be
~4x10-21. The antenna will operate at a temperature of 20 mK. An other
similar detector is being built in São Paulo, which will strongly
increase the chances of detection by looking at coincidences. The
sources we are aiming at are for instance, non-axisymmetric
instabilities in rotating single and binary neutron stars, small
black-hole or neutron-star mergers etc.
