- Several prototypes of the Transition Radiation Tracker for the ATLAS experiment at the LHC have been built and tested at the CERN SPS accelerator. Results from detailed studies of the straw-tube hit registration efficiency and drift-time measurements and of the pion and electron spectra without and with radiators are presented.

- The ATLAS Transition Radiation Tracker (TRT) performance depends critically on the choice of the active gas and on its properties. The most important operational aspects, which have led to the final choice of the active gas for the operation of the TRT at the LHC design luminosity, are presented. The TRT performance expected at these conditions is reviewed, including pile-up effects at high luminosity. (C) 2004 Elsevier B.V. All rights reserved.

- In order to reach the EU 2020 goals for the climate, Danish vocational training units are currently in a process of institutional change triggered by the need of providing energy, and new process competences for the skilled and semiskilled workforce active in construction. The aim of the present paper is to analyze enablers and barriers for this institutional change. The vocational education system in Denmark is strongly institutionalised with unions, employer's associations and the schools in central roles. Drawing on institutional theory contributions on labour market -, educational - and professional institutions, the paper presents a study of institutional work inside and across schools and craft disciplines working in SMEs involved in new building and renovation with an energy aspect. Collaboration between four education committees for carpenters, masons, electricians and plumbers and interviews with seven companies come to focus on competences of interdisciplinary collaboration and sustainable innovation in SME. The anticipation of future building regulation of 2015 and 2020 creates an institutional pressure in education for change including handling differentiated demands of customers and contractors, not always just following regulation but occasionally ahead of it. At a time this needs to be balanced with customer needs with a comfort orientation and issues of cost and financing. The committees act in a contradictory, sometimes conservative manner in this change of institutions of knowing. In the future specialization will be supplemented by horizontal and vertical interdisciplinary and innovative competences integrating the complex process industrialized construction sector. Schools, teachers and digital teaching materials need be developed to support this change supported by front running companies and results from innovative building projects. The education committees in Denmark can have a leading role in this development and set high and motivational standards for the improvements. The analysis sees however a lot more barriers than enablers.

DEVELOPMENT OF A HIGH INTENSITY NEUTRON SOURCE AT THE EUROPEAN SPALLATION SOURCE : THE HIGHNESS PROJECT
- 2022

Konferensbidrag (refereegranskat)abstract
- The European Spallation Source (ESS), presently under construction in Lund, Sweden, is a multidisciplinary international laboratory that will operate the world’s most powerful pulsed neutron source. Supported by a 3M Euro Research and Innovation Action within the EU Horizon 2020 program, a design study (HighNESS) is now underway to develop a second neutron source below the spallation target. Compared to the first source, located above the spallation target and designed for high cold and thermal brightness, the new source will provide higher intensity, and a shift to longer wavelengths in the spectral regions of cold (2-20 Å), very cold (VCN, 10-120 Å), and ultra cold (UCN, > 500 Å) neutrons. The core of the second source will consist of a large liquid deuterium moderator to deliver a high flux of cold neutrons and to serve secondary VCN and UCN sources, for which different options are under study. The features of these new sources will boost several areas of condensed matter research and will provide unique opportunities in fundamental physics. Part of the HighNESS project is also dedicated to the development of future instruments that will make use of the new source and will complement the initial suite of instruments in construction at ESS. The HighNESS project started in October 2020. In this paper, the ongoing developments and the results obtained in the first year are described.
