CLIC Detector and Physics Status

This contribution to LCWS2016 presents recent developments within the CLICdp collaboration. An updated scenario for the staged operation of CLIC has been published; the accelerator will operate at 380 GeV, 1.5 TeV and 3 TeV. The lowest energy stage is optimised for precision Higgs and top physics, while the higher energy stages offer extended Higgs and BSM physics sensitivity. The detector models CLIC_SiD and CLIC_ILD have been replaced by a single optimised detector; CLICdet. Performance studies and R&D in technologies to meet the requirements for this detector design are ongoing.Comment: Talk presented at the International Workshop on Future Linear Colliders (LCWS2016), Morioka, Japan, 5-9 December 2016.

Ethics Matters: The Integration of Ethical Considerations in Management Accounting Textbooks

This paper examines the integration of ethical considerations in management accounting (MA) education. Drawing on the work of Alisdair MacIntyre, it is argued that MA instruments such as performance measurement are not morally neutral, but instead bear moral implications. Therefore, this paper contends that MA students should be trained to take these moral implications into consideration alongside MA's technical aspects. A content analysis is carried out to examine the integration of ethical considerations in top-ranked MA textbooks. The findings indicate that these textbooks, particularly the introductory textbooks, marginally integrate ethical considerations. Furthermore, the findings point to the risk of detaching ethical considerations from the discussion of MA's technical aspects, which may weaken the potential of the ethical considerations and turn them into ‘afterthoughts’. Finally, this paper offers practical suggestions for the improvement of the integration of ethical considerations in MA education and concludes with directions for future research

Effects of Vacancies near Substitutional Implants on Trapping and Desorption of Helium - A Simulation

Trapping of He by vacancies and drainage of He from substitutional implants (Ag and Kr in W) to nearby vacancies are investigated using static lattice calculations. The calculations indicate that drainage of He will occur to vacancies within a radius of 2.5 lattice units from the implant. Furthermore the trapping probability of substitutional and interstitial random walkers on a bcc lattice by substitutional traps or vacancies is calculated. When implantation-produced vacancies are present in the vicinity of the observed trap a shielding effect occurs. Trapping constants are calculated with two random walk models for both the unshielded and the shielded defect. For the latter several configurations were taken. The results show that shielding of a defect by one vacancy at a distance of three lattice units leads already to a reduction of He trapping by that defect of 30% to 40%.
