Prototype of high accuracy single input phase measurement instrument

August 2, 2022
Author(s)
Nicholas G. Paulter Jr., Ioan Tudosa, Francesco Picariello, Pasquale Daponte, Luca De Vito, Sergio Rapuano
A prototype implementation of a phase measurement method (PMM) for a sine-wave signal delivered at the output port of a generator and its experimental assessment is presented. This PMM is capable of measuring the output phase of a sine-wave signal respect

Detection of individual spin species via frequency-modulated charge pumping

February 2, 2022
Author(s)
James Ashton, Mark Anders, Jason Ryan
We utilize the recently developed frequency-modulated charge pumping technique to detect a single charge per cycle, which strongly suggests a single Si/SiO2 interface trap. This demonstration in sub-micron MOSFETs, in which scaling of the gate oxide yields

Using CO2 as a Ventilation Clue

October 7, 2021
Author(s)
Dustin Poppendieck
The science has demonstrated that risk reduction for COVID-19 transmission in classrooms specifically includes implementing masks, increased spacing, outdoor breaks, upgraded filtration, and improved ventilation. Increasing ventilation will reduce the

Surface topography process signatures in nickel superalloy 625 additive manufacturing

September 23, 2021
Author(s)
Jason Fox, Angela Allen, Brigid Mullany, Ed Morse, Romaine Isaacs, Marc Lata, Aarush Sood, Christopher Evans
Prior analyses of surface measurements performed – by several groups – on laser powder bed fused metals have tended to use ISO standard short wavelength filters and focus on weld tracks, "chevrons" (melt pool wake), and particles. This work, utilizing two

Processing Pulses from TES Microcalorimeter X-ray Detectors

August 6, 2021
Author(s)
Terrence Jach, Stephan M. Thurgate
Microcalorimeter x-ray detectors employing a transition-edge sensor are capable of very high energy resolution, but this depends on an understanding of the readout process. The combination of thermal cooling and thermoelectric feedback present in most

Impact ionization-induced bistability in CMOS transistors at cryogenic temperatures for capacitorless memory applications

July 29, 2021
Author(s)
Alexander Zaslavsky, Curt A. Richter, Pragya Shrestha, Brian Hoskins, Son Le, Advait Madhavan, Jabez J. McClelland
Cryogenic operation of complementary metal oxide semiconductor (CMOS) silicon transistors is crucial for quantum information science, but it brings deviations from standard transistor operation. Here we report on sharp current jumps and stable hysteretic

NetSimulyzer: A 3D Network Simulation Analyzer for ns-3

July 16, 2021
Author(s)
Evan Black, Samantha Gamboa Quintiliani, Richard A. Rouil
The increased complexity of network protocols and scenarios simulated using ns-3 is making the verification of simulation correctness and the analysis of simulation outputs a challenging task. In this paper, we present a new and flexible visualization tool

Dipole-Dipole Frequency Shifts in Multilevel Atoms

June 30, 2021
Author(s)
Andre Cidrim, Asier Pineiro Orioli, Christian Sanner, Ross B. Hutson, Jun Ye, Romain Bachelard, Ana Maria Rey
Dipole-dipole interactions lead to frequency shifts which are expected to limit the performance of next generation atomic clocks. In this work, we compute dipolar frequency shifts accounting for the intrinsic atomic multilevel structure in standard Ramsey
