A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. This Review summarises the status and the recent advances on muon colliders design, physics and detector studies. The aim is to provide a global perspective of the field and to outline directions for future work.
Energy storage capacitors are used in large quantities in high power converters for particle accelerators. In this application capacitors see neither a DC nor an AC voltage but a combination of the two. The paper presents a new power converter explicitly designed to perform accelerated testing on these capacitors and the results of the tests.Presented at: EPE 2015, 7-10 September 2015, Geneva, Switzerland Geneva, Switzerland October, 2015 Accelerated lifetime testing of energy storage capacitors used in particle accelerators power converters AbstractEnergy storage capacitors are used in large quantities in high power converters for particle accelerators.

This paper presents an original experience in the design of electrical drives. A complete integration has been realised among the design of the motor, converter and control. This solution became possible thanks to the application of a software tool called Electromechanical System Simulator (EMSS), whose Finite Element Method (FEM) core is Maxwell2D, that allowed the electromagnetic design of the motor and then the generation of a SPICE model of this device so to allow the analysis of the interaction with the Converter and the control structure. This solution presents the interesting aspect of reaching an high detail in the analysis of the electromagnetic field inside the machine without disregarding the circuit-based approach of the converter design.
The main power supply of Proton-Synchrotron (PS) accelerator is one of the biggest at CERN. The old rotating machine system has been replaced with a new NPC based DC/DC power supply named POPS (Power system for PS main magnets) with capacitor banks as energy storage mean. POPS is in operation since February 2011. The operation of the PS accelerator requires a specific design of the control system with very high performance requirements in term of accuracy and precision. This paper describes the main lines of the control strategies analyzing the problems encountered and the solutions adopted. The performances of the converter are presented throughout the paper.

In the frame of the LHC Injectors Upgrade (LIU) project, a new main power supply (MPS) for the PSBooster accelerator is required. The largest element of the new MPS is the 18 MW main power converter (MPC). The paper presents the design of the MPC control software, using Rapid Control Prototyping.Presented at: EPE 2015, 7-10 September 2015, Geneva, Switzerland Geneva, Switzerland October, 2015
