Upgrades Of the SPS, Transfer Line and LHC Injection Protection Devices For the HL-LHC Era

The challenging High Luminosity LHC (HL-LHC) beam requirements will lead in the future to unprecedented beam parameters along the LHC injector chain. In the SPS accelerator these requests translate into about a factor two higher intensity and brightness than the present design performance. In addition to the challenge of producing and accelerating such beams, these parameters affect the resistance of the existing equipment against beam impact. Most of the protection devices in the SPS ring, its transfer lines and the LHC injection areas will be put under operational constraints which are beyond their design specification. The equipment concerned has been reviewed and their resistance to the HL-LHC beams checked. Theoretical and simulation studies have been performed for the SPS beam scraping system, the protection devices and the dump absorbers of the SPS-to-LHC transfer lines, as well as for the LHC injection protection devices. The first results of these studies are reported, together with the future prospects.Comment: 3 p. Presented at 4th International Particle Accelerator Conference (IPAC 2013

How management control systems can facilitate a firm's strategic renewal and creation of financial intelligence

This chapter presents how management control systems and financial intelligence can facilitate a firm’s strategic renewal. Although the strategic accounting literature has recognized the importance of financial intelligence to a firm’s strategic decision making and formulation of strategy, the question of how a management control system (MCS) can help a firm to revamp and reallocate its resources has been overlooked in the prior strategy literature. In response, this chapter presents a conceptual model, which presents how advanced management accounting systems can foster a firm’s strategic renewal in light of the available theoretical foundations (the strategy implementation view, the dynamic capability perspective, and management accounting). This chapter advances managers’ understanding of firm’s renewal practices through the use of an MCS. Practical examples have been used to illustrate how firms renew their business operations in practice.fi=vertaisarvioitu|en=peerReviewed

Injection protection upgrade for the HL-LHC

The injector complex of the LHC is undergoing important changes in the light of the LIU project to provide brighter beams to the LHC. For this reason and as part of the High Luminosity LHC project the injection protection system of the LHC will be upgraded in the Long Shutdown 2 (2018-2019) to be able to protect downstream elements against injection failures with the high brightness, high intensity HL-LHC beams. The upgraded LHC injection protection system will consist of a segmented injection protection absorber TDIS and auxiliary collimators and masks. The layout modifications are described, and the machine element protection and absorber jaw robustness studies are presented for the new systems.
