Report from the ABP Computing Working Group (ABP-CWG) activities in 2017-18

The Accelerators and Beam Physics (ABP) Group is responsible for studying and understanding the beam dynamics over the complete CERN Accelerator Complex through theoretical, simulation and experimental studies. For this purpose, over the years members of the ABP group have developed and/or become proficient users of a large number of simulation codes, needed for all studies covering hadron sources and linear accelerators, machine optics and single particle dynamics, coherent and incoherent collective effects. Use cases are meant to cover not only the current CERN accelerators, but also the design and operating scenarios of future accelerators (e.g. CLIC, FCC). The activities of development, deployment, maintenance and support of the accelerator physics computer codes are coordinated in the framework of the ABP Computing Working Group. The purpose of this note is to introduce the ABP Computing Working Group in terms of mandate and functions, and provide a compact summary of the activities carried out in 2017-18, while highlighting the points that require close follow up.
