Professors of German Universities (e.g. Cologne, Heidelberg) in Italy (1400-1550) and the Repertorium Academicum Germanicum (RAG)

The RAG’s task is to collect biographical and social data on those Theologians, Jurists, Physicians, and Masters of Arts, who studied at a university between 1250 and 1550. The information is entered into a prosopographic database that will finally cover the entire territory of the Holy Roman Empire. Non-graduated noble visitors of universities are also taken into account. The RAG, which in the end will be a “who is who” of the scholars of the Old Empire, offers divers new and interdisciplinary perspectives due to its vast collection of data. Qualitative and quantitative statements on the intellectual elite of the Empire, their European networks, as well as institutional and territorial comparisons will be possible. Thus the scholars' role in pre-modern society can be described on a firm empirical basis and explained within the framework of modern educational research, with special reference to social, cultural, and scientific history. Up to 50,000 scholars are to be expected.

Measurement of the drift field in the ARGONTUBE LAr TPC with 266 nm pulsed laser beams

ARGONTUBE is a liquid argon time projection chamber (LAr TPC) with a drift field generated in-situ by a Greinacher voltage multiplier circuit. We present results on the measurement of the drift-field distribution inside ARGONTUBE using straight ionization tracks generated by an intense UV laser beam. Our analysis is based on a simplified model of the charging of a multi-stage Greinacher circuit to describe the voltages on the field cage rings.

What are the causes for the spread of GLE parameters deduced from NM data?

Investigations have shown that the analysis results of ground level enhancements (GLEs) based on neutron monitor (NM) data for a selected event can differ considerably depending the procedure used. This may have significant consequences e.g. for the assessment of radiation doses at flight altitudes. The reasons for the spread of the GLE parameters deduced from NM data can be manifold and are at present unclear. They include differences in specific properties of the various analysis procedures (e.g. NM response functions, different ways in taking into account the dynamics of the Earth’s magnetospheric field), different characterisations of the solar particle flux near Earth as well as the specific selection of NM stations used for the analysis. In the present paper we quantitatively investigate this problem for a time interval during the maximum phase of the GLE on 13 December 2006. We present and discuss the changes in the resulting GLE parameters when using different NM response functions, different model representations of the Earth’s magnetospheric field as well as different assumptions for the solar particle spectrum and pitch angle distribution near Earth. The results of the study are expected to yield a basis for the reduction in the spread of the GLE parameters deduced from NM data.

Das Repertorium Academicum Germanicum (RAG). Ein digitales Forschungsvorhaben zur Geschichte der Gelehrten des alten Reiches (1250-1550)

This article aims at presenting an already existing research project. The Repertorium Academicum Germanicum (RAG) is supposed to be a "Who’s who" of the graduated and noble scholars of the late medieval Empire. It is designed to record biographical and social data of graduated theologians, jurists, physicians and Masters of Art as well as data of nobles from universities between 1250 and 1550. Furthermore, the project focuses on their examinations, networks, fields of activity in ecclesiastical and secular offices as well as their achievements and legacies (books, treatises, tombs etc). Right now, over 49.000 prosopographic entries are stored in the RAG database, partly available online (www.rag-online.org) and combined with digital maps (infographics), which already provide a basis for research in academic mobility determined by the top scholars of the time. In a next step, it should be possible to draw conclusions not only about personnel and knowledge transfer from university to society, its effects on political systems, daily life, the emergence of new occupational groups and professions, but also about cultural exchange within Europe.
