Renegotiating tradition on Radio Zimbabwe

The article focuses on the renegotiation of the Shona past within public service broadcasting as epitomized by Chakafukidza Dzimba Matenga, a popular prime-time talk programme offered by the national languages channel, Radio Zimbabwe. The analysis shows how Shona traditional communicative structures and figures of traditional authority are reconfigured in the context of adult talk-radio intended for male and female listeners located in both traditional (rural) and non-traditional (urban) spaces. The article draws on the theory of the ‘invention of tradition’ by Hobsbawm and Ranger to explore the role of broadcasting in processes of continuity and change in Zimbabwe. The article examines the ‘no sense of place’ that results from the anticipation of the reception of the adult talk in the programme in the context of the ‘shifting social geographies’ that Meyrowitz perceives to be increasingly evident in the way the mass media are experienced in many contemporary societies.

The Design and Construction of the Chips Water Cherenkov Neutrino Detector

International audienceCHIPS (CHerenkov detectors In mine PitS) was a prototype large-scale water Cherenkov detector located in northern Minnesota. The main aim of the R&D project was to demonstrate that construction costs of neutrino oscillation detectors could be reduced by at least an order of magnitude compared to other equivalent experiments. This article presents design features of the CHIPS detector along with details of the implementation and deployment of the prototype. While issues during and after the deployment of the detector prevented data taking, a number of key concepts and designs were successfully demonstrated

Scalable DAQ system operating the CHIPS-5 neutrino detector

International audienceThe CHIPS R&D project focuses on development of low-cost water Cherenkov neutrino detectors through novel design strategies and resourceful engineering. This work presents an end-to-end DAQ solution intended for a recent 5 kt CHIPS prototype, which is largely based on affordable mass-produced components. Much like the detector itself, the presented instrumentation is composed of modular arrays that can be scaled up and easily serviced. A single such array can carry up to 30 photomultiplier tubes (PMTs) accompanied by electronics that generate high voltage in-situ and deliver time resolution of up to 0.69 ns. In addition, the technology is compatible with the White Rabbit timing system, which can synchronize its elements to within 100 ps. While deployment issues did not permit the presented DAQ system to operate beyond initial evaluation, the presented hardware and software successfully passed numerous commissioning tests that demonstrated their viability for use in a large-scale neutrino detector, instrumented with thousands of PMTs
