| MOPIK040 | Value Engineering of an Accelerator Design During Construction | 592 |
|
||
| Value engineering is an important part of the process of designing and realising large-scale installations such as high power accelerators. This typically occurs during the later part of the design stage of the system, however such exercises may also be requested by funding bodies at later stages in order to manage project contingency. Naturally, the later this is done, the more challenging it becomes. In this paper we report on a recently concluded Value Engineering effort at the European Spallation Source. The challenges presented by the initiation of such an exercise during the construction phase are discussed. In addition, we present and discuss the various options that we examined, and indicate the philosophy and figures of merit used to narrow down these options. The final conclusion will be presented. | ||

| MOPVA090 | ESS Superconducting RF Collaboration | 1068 |
|
||
| The European Spallation Source (ESS) project is a neutron-scattering facility, currently under construction by a partnership of at least 17 European countries, with Sweden and Denmark as host nations. The ESS was designated a European Research Infrastructure Consortium, or ERIC, by the European Commission in October of 2015. Scientists and engineers from 50 different countries are members of the workforce in Lund who participate in the design and construction of the European Spallation Source. In complement to the local workforce, the superconducting RF linear accelerator is being prototyped and will be constructed based on a collaboration with European institutions: CEA-Saclay, CNRS-IPN Orsay, INFN-LASA, STFC-Daresbury, Uppsala and Lund Universities. After a description of the ESS collaborative project and its in-kind model for the SRF linac, this article will introduce the linac component first results. | ||

| MOPVA091 | Investigation of HOM Frequency Shifts Induced by Mechanical Tolerances | 1071 |
|
||
| We present Higher Order Mode (HOM) studies on ESS Medium-Beta cavity of INFN-LASA design, including both simulation and measurement results. Mechanical tolerances of the fabrication process might shift HOMs frequencies toward harmonics of the bunch frequency. Both simulation and measurements at room and cryogenic temperature show that INFN LASA cavity is fully compatible with ESS requirements. | ||

A Fireside Talk | |
|
||
| Guest: John Womersley, former CEO of the UK's Science and Technology Facilities Council (STFC), and current Director General of ESS. In his role as CEO of the STFC since 2011, Womersley led one of Europe's largest multidisciplinary research organisations. He was directly involved in the UK's decision to join ESS in 2014. He is also a leading figure in European science policy as the former chair of the European Strategy Forum on Research Infrastructures (ESFRI), the leading forum for prioritizing strategic investment in research infrastructure in Europe. My vision for ESS is that we should look broader than being the world's best neutron scattering facility, said Womersley. We should also aim to be what everyone looks to in terms of Big Science. Later during the session, Mikael Eriksson from MAX IV and Søren Pape Møller from Aarhus University join the discussion. | ||
