Resonant gravitational wave detectors have evolved from the room temperature bars of J. Weber to the sub-Kelvin bars of the Rome and Padua groups. Their strain sensitivity h = ΔLL is now in the range of 10−19, thought to be enough to detect events

The temperature dependence of the pressure at a constant volume in solid 4He in the low-density hcp phase has been measured. The measurements are analyzed in terms of a localized vacancy model and the free Bose gas model of vacancies in solid helium.

The number of observed cycles of a coalescing binary, the signal-to-noise ratio with matched filtering, the event rate and the accuracies in the determination of the chirp mass, time of arrival and the amplitude are calculated for a spherical detecto

Here we present a status report of the Schenberg antenna. In the past three years it has gone to a radical upgrading operation, in which we have been installing a 1K pot dilution refrigerator, cabling and amplifiers for nine transducer circuits, desi

Large metallic cylinders with a mass of several tons have been cooled to liquid helium temperatures and recently down to T ~ 100 mK leading to the most sensitive gravitational wave detector (NAUTILUS). The sensitivity is still not enough to detect wa

We have achieved high-spin polarizations in concentrated mixtures of 3He in 4He using the rapid-melting method originally suggested by Castaing and Nozieres for pure 3He. Polarizations well above the equilibrium value (greater than 10%) were obtained

International audience; A polarized 3He ion source has been developed at RCNP for intermediate and high energy spin physics. Though we started with an OPPIS (Optical Pumping Polarized Ion Source), it could not provide highly polarized 3He beam becaus
