Progress on the Astrometric Gravitation Probe design
Mario Gai, Alberto Vecchiato, Alberto Riva +13
The Astrometric Gravitation Probe mission is a modern version of the 1919 Dyson-Eddington-Davidson experiment, based on a space-borne telescope with a permanent built-in eclipse, p…
The ASTRA project: a doorway to future astrometry
Mario Gai, Zhaoxiang Qi, Mario G. Lattanzi +15
Astrometric Science and Technology Roadmap for Astrophysics (ASTRA) is a bilateral cooperation between China and Italy with the goal of consolidating astrometric measurement concep…
Systematic errors in the correlation method for Johnson noise thermometry: residual correlations due to amplifiers
Luca Callegaro, Marco Pisani, Massimo Ortolano
Johnson noise thermometers (JNT) measure the equilibrium electrical noise, proportional to thermodynamic temperature, of a sensing resistor. In the correlation method, the same res…
An absolute Johnson noise thermometer
Luca Callegaro, Vincenzo D'Elia, Marco Pisani +1
We developed an absolute Johnson noise thermometer (JNT), an instrument to measure the thermodynamic temperature of a sensing resistor, with traceability to voltage, resistance and…
Very simple FET amplifier with a voltage noise floor less than 1 nV/sqrt(Hz)
Luca Callegaro, Marco Pisani, Alessio Pollarolo
A field-effect transistor (FET) amplifier for small voltage signals is presented. Its design is elementary and the construction can be afforded by anyone. Despite its simplicity, w…
