Tantalum Damascene Coplanar Waveguide Resonators Fabricated Using 300 mm Scale Processes
Ekta Bhatia, Yingge Du, Krishna P Koirala +12
Surface oxides contribute to losses in superconducting transmon devices resulting in degraded performance. We explore the use of the damascene process to replace the sidewall nativ…
Cyclotron Radiation Signal Characterization in Resonant Cavities for the Project 8 Neutrino Mass Experiment
A. Ashtari Esfahani, S. Bhagvati, H. P. Binney +60
Many experimental methods in physics require understanding radiation from single particles into non-trivial electromagnetic mode structures. Such characterization is critical for C…
Dynamics of Magnetic Evaporative Beamline Cooling for Preparation of Cold Atomic Beams
A. Ashtari Esfahani, S. Bhagvati, S. Böser +55
The most sensitive direct neutrino mass searches today are based on measurement of the endpoint of the beta spectrum of tritium to infer limits on the mass of the unobserved neutri…
The real-time data processing and acquisition system for Project 8 Phase II
A. Ashtari Esfahani, A. Banducci, S. Böser +36
In Phase II of the Project 8 neutrino mass experiment, electrons from the decays of tritium or Kr are detected via their 26 GHz cyclotron radiation whil…
Antenna Arrays for CRES-based Neutrino Mass Measurement
A. Ashtari Esfahani, S. Bhagvati, S. Böser +65
CRES is a technique for precision measurements of kinetic energies of charged particles, pioneered by the Project 8 experiment to measure the neutrino mass using the tritium endpoi…
Calorimetric Wire Detector for Measurement of Atomic Hydrogen Beams
M. Astaschov, S. Bhagvati, S. Böser +53
A calorimetric detector for minimally disruptive measurements of atomic hydrogen beams is described. The calorimeter measures heat released by the recombination of hydrogen atoms i…
