Instrumentation issues for neutrinoless double beta decay (#4358)

G. Gratta1

1 Stanford University, Stanford, California, United States of America


I will review the technical requirements and instrumentation needs of modern double-beta decay experiments. Several technologies are implemented in various detectors, ranging from massive use of Ge counters, bolometric detectors and large time projection chambers in liquid and gas phase. The common threads are exquisitely low radioactive background and holistic design of the instrumentation, to fully optimize the detector sensitivity and optimally use the source material that, in most cases, requires isotopic enrichment.

Smaller and Sooner: Exploiting new superconductor technology to accelerate fusion’s development (#4360)

Rare-Earth Barium Copper oxide (REBCO) superconductor (SC) tapes are a newly available technology that promise to revolutionize plasma and fusion research. REBCO are superconducting at liquid nitrogen temperature, providing easy access to ~1-2 tesla steady-state magnetic fields in the laboratory and, unlike standard SCs, have no degradation of their critical current at high magnetic fields when sub-cooled. These features allow >23 tesla magnetic coils, double the B-field of standard SC such as used in ITER, as well as the design of demountable SC coils. The implications of such coils have been examined in ARC, a conceptual tokamak fusion pilot plant for electricity production, and in SPARC, an extremely compact rapid-prototype burning plasma device. For example, exploiting the B4 dependence in fusion power density, ARC produces >500 MW in a device 1/8th the volume of ITER. Demountable coils permit modular internal components, a simple liquid immersion blanket for fusion energy extraction, and advanced high surface area topologies for heat exhaust. Compact, high-B tokamaks provide for robust steady-state operational regimes with largely demonstrated physics. Critical science and technology R&D issues towards ARC and SPARC are discussed that would enable this attractive path to smaller, more flexible fusion devices.
