Superconducting cavity transducer for resonant gravitational radiation antennas
Parametric transducers, such as superconducting rf cavities, can boost the bandwidth and sensitivity of the next generation resonant antennas, thanks to a readily available technology. We have developed a fully coupled dynamic model of the system ”antenna– transducer” and worked out some estimates of signal–to–noise ratio and the stability conditions in various experimental configurations. We a...
متن کاملTorsion-bar antenna for low-frequency gravitational-wave observations.
We propose a novel type of gravitational-wave antenna, formed by two bar-shaped test masses and laser-interferometric sensors to monitor their differential angular fluctuations. This antenna has a fundamental sensitivity to low-frequency signals below 1 Hz, even with a ground-based configuration. In addition, it is possible to expand the observation band to a lower limit determined by the obser...
متن کاملRadiation Shielding for Superconducting RF Cavity Test Facility at A0
The results of Monte Carlo radiation shielding study performed with the MARS15 code for the vertical test facility at the A0 north cave enclosure at Fermilab are presented and discussed.
متن کاملHigh Performance Simulation for Resonant-Mass Gravitational Radiation Antennas
In this paper the design and validation of a high performance simulation is discussed that is of critical value to the feasibility study of the GRAIL project, the aim of which is to build a gravitational radiation antenna. Two relatively simple simulation models of this antenna are shown to be too restrictive for our purposes, necessitating the development of a simulation program that utilizes ...
متن کاملRydberg Atoms and Radiation in a Resonant Cavity Ii. Experiments
We present various experiments involving Rydberg atoms interacting with resonant microwave electromagnetic fields inside a cavity, allowing to check different features of the theory presented in the previous paper. We first describe experiments about superradiant emission by Rydberg states in the cavity, also called transient Rydberg atoms maser; the evolution of the system is detected either o...
