A superconducting nanowire single-photon camera with 400,000 pixels.

For the past 50 years, superconducting detectors have offered exceptional sensitivity and speed for detecting faint electromagnetic signals in a wide range of applications. These detectors operate at very low temperatures and generate a minimum of excess noise, making them ideal for testing the non-local nature of reality, investigating dark matter, mapping the early universe and performing quantum computation and communication. Despite their appealing properties, however, there are at present no large-scale superconducting cameras-even the largest demonstrations have never exceeded 20,000 pixels.

Evaluation of a clinical and translational research initiative: Developing and implementing a collaborative evaluation process in CAIRIBU.

Funding for large research initiatives, such as those funded through the National Institutes of Health U mechanism, has increased since 2010; however, there is little published research on how to evaluate the success of such initiatives. Here, we describe the collaborative evaluation planning process undertaken by the Interactions Core of the Collaborating for the Advancement of Interdisciplinary Research in Benign Urology (CAIRIBU) research community, a clinical and translational research initiative funded by the National Institute of Diabetes and Digestive and Kidney Diseases. Evaluation is necessary to measure the impact of our work and to allow for continuous improvement efforts of CAIRIBU activities and initiatives.

Collaborating for the advancement of interdisciplinary research in benign urology (CAIRIBU): outcomes, effectiveness, and future directions of annual CAIRIBU meetings.

The 5 annual CAIRIBU Meeting (CAIRIBU = Collaborating for the Advancement of Interdisciplinary Research in Benign Urology) was held November 29-December 2, 2022 in Bethesda, MD and organized by the CAIRIBU (U24) Interactions Core. Altogether, nearly 100 individuals participated, representing U54 Urology OBrien Centers, P20 Urology Centers, and K12 Urology Career Development Programs currently and previously funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Several NIDDK Program Officers participated in the meeting, including those representing the NIDDK Central Repository and several urologic research consortia.

Self-heating hotspots in superconducting nanowires cooled by phonon black-body radiation.

Controlling thermal transport is important for a range of devices and technologies, from phase change memories to next-generation electronics. This is especially true in nano-scale devices where thermal transport is altered by the influence of surfaces and changes in dimensionality. In superconducting nanowire single-photon detectors, the thermal boundary conductance between the nanowire and the substrate it is fabricated on influences all of the performance metrics that make these detectors attractive for applications.

Large-Area Superconducting Nanowire Single-Photon Detectors for Operation at Wavelengths up to 7.4 μm.

The optimization of superconducting thin-films has pushed the sensitivity of superconducting nanowire single-photon detectors (SNSPDs) to the mid-infrared (mid-IR). Earlier demonstrations have shown that straight tungsten silicide nanowires can achieve unity internal detection efficiency (IDE) up to λ = 10 μm. For a high system detection efficiency (SDE), the active area needs to be increased, but material nonuniformity and nanofabrication-induced constrictions make mid-IR large-area meanders challenging to yield.
