The presentation will give a brief overview on the performance of the machine protection system during the 2010 run with an emphasis on highlighting suspicious events which still need to be fully understood. Improvements and mitigations of potential holes in the protection systems will be discussed along with their impact on the 2011 run. A summary of the currently available tools and...

4. LBDS and abort gap cleaning

A number of possible failure scenarios and estimated occurrence were defined for the LHC Beam Dump System (LBDS). An analysis of the LIBDS performance during the first year of the LHC operation is presented and compared with respect to requirements and expectations. Several qualification tests have been regularly performed to assess the protection provided by the system in the eventuality of a...

5. How low can we go? Getting below 3.5 m b*

The LHC has made remarkable progress during 2010, fulfilling its ambitious goal for the year in terms of luminosity. For 2011, even higher performance has to be reached. One way of further increasing luminosity is to reduce the beam size at the interaction points, which is determined by the optical function beta∗. However, when beta∗ is decreased, so is the margin to the triplet aperture in...

6. Injection protection: are we taking it seriously, how can we make it safer?

V. Kain

08/12/2010, 14:50

The experience with the injection protection system during the 2010 run will be summarized, the setting-up times and stability will be evaluated. Weak points of the protections system at injection which became apparent with first high intensity experience will be discussed and solutions for 2011 presented if possible. The line between injection quality and injection protection issues will be...

7. The human factor

A. Macpherson

08/12/2010, 15:10

The presentation will address the issues of the human risk factor for the machine protection and operation of the LHC and will highlight some of the key risk situations with examples taken from the 2010 run. Emphasis is placed on risk factors that are present in the current modus operandi as well as the foreseen improvements, both procedural and otherwise, that are intended to mitigate the...
