(2022-09-08)This article describes the setup and performance of the near and far detectors in the Double Chooz experiment. The electron antineutrinos of the Chooz nuclear power plant were measured in two identically designed detectors with different average baselines of about 400 m and 1050 m from the two reactor cores. Over many years of data taking the neutrino signals were extracted from interactions in the detectors with the goal of measuring a fundamental parameter in the context of neutrino oscillation, the mixing angle θ13. The central part of the Double Chooz detectors was a main detector comprising four cylindrical volumes filled with organic liquids. From the inside towards the outside there were volumes containing gadolinium-loaded scintillator, gadolinium-free scintillator, a buffer oil and, optically separated, another liquid scintillator acting as veto system. Above this main detector an additional outer veto system using plastic scintillator strips was installed. The technologies developed in Double Chooz were inspiration for several other antineutrino detectors in the field. The detector design allowed implementation of efficient background rejection techniques including use of pulse shape information provided by the data acquisition system. The Double Chooz detectors featured remarkable stability, in particular for the detected photons, as well as high radiopurity of the detector components.
- Habitat Conservation: The dynamics of direct and indirect paymentsConrad, J. M.; Ferraro, Paul J. (2001)This paper examines the dynamic efficiency of direct and indirect payments for habitat conservation, as well as the preferences of donors who make the payments. A direct (or performance) payment is an annual payment to a landowner based on the number of hectares of undisturbed habitat that the landowner has preserved. An indirect payment is an annual payment to a landowner that subsidizes the use of other, non-habitat, inputs to an "eco-friendly" activity (e.g., eco-tourism). Direct payments are dynamically efficient. They can achieve a desired level of preserved habitat at lower levels of the other, non-habitat, inputs. Direct payments, however, may not be preferred by the donor who funds the conservation effort. The analytical model is calibrated to the Ranomafana National Park in Madagascar. For the amount of funds invested in Ranomafana by international conservation organizations, direct payments generate dramatically lower costs for the conservation agent and higher profit levels for the rural residents who control the fate of the ecosystem.

(2022-05-17)Primary challenges for current and future precision neutrino experiments using liquid argon time projection chambers (LArTPCs) include understanding detector effects and quantifying the associated systematic uncertainties. This paper presents a novel technique for assessing and propagating LArTPC detector-related systematic uncertainties. The technique makes modifications to simulation waveforms based on a parameterization of observed differences in ionization signals from the TPC between data and simulation, while remaining insensitive to the details of the detector model. The modifications are then used to quantify the systematic differences in low- and high-level reconstructed quantities. This approach could be applied to future LArTPC detectors, such as those used in SBN and DUNE.
