AbstractAbstract
[en] The HL-LHC has ambitious integrated luminosity goals in the region of 250 fb"−"1 per year. This level of performance will required excellent machine availability. After a definition of terms and assumptions, the availability to date is reviewed while noting the importance of accurate and reliable tracking. Other possible areas of improvement and future challenges which could impact the overall availability are then discussed. Estimates based on extrapolation from present experience are given. Injector availability will also be important for the overall LHC performance and the need for sustained, well-planned consolidation is recalled

AbstractAbstract
[en] Fermilab has proposed the construction of a new 150 GeV accelerator called the Main Injector. This accelerator will replace the existing Main Ring in all its functions. The Main Injector is expected to perform at a significantly higher level than the Main Ring as measured either in protons delivered per cycle, protons delivered per second, or transmission efficiency. It is anticipated that following construction of this machine the antiproton production rate at Fermilab will exceed 1x1011 p/hour and that a luminosity in excess of 5x1031 cm-2sec-1 will be supported in the existing collider. Additional benefits accruing from this accelerator include reduction of backgrounds at the collider detectors, potential development of a third interaction region in the Tevatron, and the availability of slow extracted 120 GeV beams year around. Design criteria and parameters of the Main Injector will be discussed. (author) 1 fig., 3 tabs

AbstractAbstract
[en] Studies aimed at increasing the luminosity of the CERN Linear Collider (CLIC) for a given power by introducing multiple bunches during a single RF fill are described. Long range transverse wakefields are reduced by detuning the dipole mode frequencies and beam loading is compensated by partial section filling and tapered power pulses

AbstractAbstract
[en] The beam parameters in the LHC resulting from the Performance Improvement Consolidation (PIC) activities will be briefly recalled and motivated assuming that LINAC4 will be operational as PS-Booster Injector. The corresponding limitations in the LHC are outlined. Based on the above performance an estimate of the LHC yearly integrated luminosity will be provided. The evaluation of the need and extent of the performance and reliability improvement for some of the PIC items might imply additional information: the necessary machine studies and the specific operational experience required during Run 2 will be summarized

AbstractAbstract
[en] In this lecture an overview is given of the present technology for high field accelerator magnets. We indicate how to get high fields and what are the most important parameters. The available conductors and their limitations are presented followed by the most relevant types of coils and support structures. We conclude by showing a number of recent examples of development magnets which are either pure R&D objects or models for the LHC luminosity upgrade

AbstractAbstract
[en] The project of a new-generation TCF is now under consideration in Novosibirsk. A novel approach of the Crab Waist collision scheme allows reaching a luminosity of 1–2 × 1035 cm-2 s-1. The other features of the facility are as follows: variable energy from 3 GeV to 4.5 GeV (c.m.), electron beam polarization, flexible usage of damping and excitation wigglers to keep high luminosity for all energy levels, etc. We discuss some of the challenges and opportunities available with the development of the project.

AbstractAbstract
[en] We present the possibilities for doing luminosity levelling at the LHC. We explore the merits and drawbacks of each option and briefly discuss the operational implications. The simplest option is levelling with an offset between the two beams. Crab cavities may also be used for levelling, as may a squeezing of the beam. There is also the possibility of using the crossing angle in order to do luminosity levelling. All of these options are explored, for the LHC and other possible new projects, together with their benefits and drawbacks
