  The LHC collimation system will require simultaneous management by the LHC control system of more than 500 jaw positioning mechanisms in order to ensure the required beam cleaning and machine protection performance in all machine phases, from injection at 450~GeV to collision at 7~TeV. Each jaw position is a critical parameter for the machine safety which could cause a beam dump. In this paper, the architecture of the LHC collimator controls is presented. The basic design to face the accurate and real-time control of the LHC collimators and the interfaces to the other components of LHC Software Application and control infrastructures are described. The full controls architecture has been tested off-line in dedicated test benches, and in the real accelerator environment in the CERN SPS during beam tests with a full scale collimator prototype. The results and the lessons learned are presented.

  The CNGS project (CERN Neutrinos to Gran Sasso) aims at directly detecting muon neutrinos-tau neutrinos oscillations. An intense muon- neutrinos beam is generated at CERN and directed towards LNGS (Laboratori Nazionali del Gran Sasso) in Italy where tau-neutrinos will be detected in large and complex detectors. An overview of the CNGS beam facility is given. Results from the primary and secondary beam line commissioning performed in summer 2006 are presented. Measurements are compared with expectations.

  The LHC machine will be a very demanding accelerator with large nonlinearities to control. Particle loss in the LHC must be actively controlled to avoid damage to the machine. Therefore any relevant adjustment to the machine must be checked beforehand with a proper modeling tool of the LHC. The LHC On-Line Modeling is an attempt to provide such an analysis tool mainly based on the MAD-X code. The goal is not to provide real-time system to control LHC but rather a way to speed up off-line analysis to give results within minutes. There will be a rich spectrum of applications like closed orbit corrections, beta-beating analysis, optimization of correctors and knob settings to name a few. This report will outline how in detail the On-Line Modeling will be in embedded in the LHC control system. It will also be reported about progress in applying this analysis tool to the SPS machine and to the commissioning of the CNGS.
