“…The design of a muon collider ring faces many of the same challenges as the collider rings of an electron-ion collider, only taken to extreme [66]. To make the most efficient use of expensive muons and reach desired luminosity levels, the muon beams have to be focused into very small spots at the IPs.…”

The genetic algorithm (GA) is a powerful technique that implements the principles nature uses in biological evolution to optimize a multidimensional nonlinear problem. The GA works especially well for problems with a large number of local extrema, where traditional methods (such as conjugate gradient, steepest descent, and others) fail or, at best, underperform. The field of accelerator physics, among others, abounds with problems which lend themselves to optimization via GAs. In this paper, we report on the successful application of GAs in several problems related to the existing Continuous Electron Beam Accelerator Facility nuclear physics machine, the proposed Medium-energy Electron-Ion Collider at Jefferson Lab, and a radio frequency gun-based injector. These encouraging results are a step forward in optimizing accelerator design and provide an impetus for application of GAs to other problems in the field. To that end, we discuss the details of the GAs used, include a newly devised enhancement which leads to improved convergence to the optimum, and make recommendations for future GA developments and accelerator applications.

Superconductivity has been the most influential technology in the field of accelerators in the last 30 years. Since the commissioning of the Tevatron, which demonstrated the use and operability of superconductivity on a large scale, superconducting magnets and rf cavities have been at the heart of all new large accelerators. Superconducting magnets have been the invariable choice for large colliders, as well as cyclotrons and large synchrotrons. In spite of the long history of success, superconductivity remains a difficult technology, requires adequate R&D and suitable preparation, and has a relatively high cost. Hence, it is not surprising that the development has also been marked by a few setbacks.This article is a review of the main superconducting accelerator magnet projects; it highlights the main characteristics and main achievements, and gives a perspective on the development of superconducting magnets for the future generation of very high energy colliders.To be published in Reviews of Accelerator Science and Technology, Vol. 5Geneva, Switzerland CERN-ATS-2013-019February 2013 Superconductivity has been the most influential technology in the field of accelerators in the last 30 years.

One of the possible next steps for HEP research relies on a high-energy hadron or muon collider. Energy of a circular collider is limited by the strength of bending dipoles and its maximum luminosity is determined by the strength of final focus quadrupoles. That is why there has been a permanent interest to higher field and higher gradient accelerator magnets from the high energy physics and accelerator communities. The maximum field of NbTi magnets used in all present high-energy machines including LHC is limited by ~10 T at 1.9 K. The fields above 10 T became possible using the Nb3Sn superconductor. Nb3Sn accelerator magnets can provide operating fields up to ~15 T and significantly increase the coil temperature margin. Accelerator magnets with operating field above 15 T require high-temperature superconductors. This paper discusses the status and main results of the Nb3Sn accelerator magnet R&D and the work towards the 20 T class magnets.
