Towards a muon collider

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

Accelerated lifetime testing of energy storage capacitors used in particle accelerators power converters

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

Control development for an 18 MW pulsed power converter using a real-time simulation platform

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

POPS: the 60MW power converter for the PS accelerator: Control strategy and performances

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

Development of a control strategy for the 18 MW power converter of the CERN PS Booster accelerator

In the frame of the Large Hadron Collider Injectors Upgrade project, a new 18 MW power converter is required for the supply of the main magnets in the PS Booster accelerator. The power converter is composed of an Active Front End (AFE) and a DC/DC converter. A 3.5 MJ energy storage capacitor bank is installed between the AFE and the DC/DC and provides power decoupling between the AC network and the load. The control strategy has been implemented onto a DSP based platform designed by CERN and validated using a 1/10.000 power scaled prototype. The paper presents the control strategy choices and results obtained

Parameter ranges for a chain of rapid cycling synchrotrons for a muon collider complex

A facility for a muon collider brings the big advantages of a compact lepton collider and a collision energy up to several TeV, well above the energy reach of conventional electron circular accelerators.However, the short lifetime of muons drives the design of the accelerator complex and collider, which makes this complex unique. A high muon survival rate and luminosity requires an extremely fast energy increase in combination with intense and ultra-short bunches. The InternationalMuon Collider Collaboration proposes a chain of rapid cycling synchrotrons (RCS) for acceleration from several tens of GeV to several TeV. The minimization of the muon decay during the acceleration process is driven by technological limitations like the maximum magnet ramp and field, and cavity gradient. We will consider different scenarios to reuse as much as possible the existing infrastructure at CERN.We will give some scaling laws for a hybrid RCS to evaluate the frequency shift due to a path variation and the trajectory variation.Finally, we will propose a preliminary parameter range for the different stages of an RCS chain
