6. BIS - BIC - SMP

Dr Benjamin TODD (CERN)

20/01/2010, 09:00

The Beam Interlock System (BIS) and Safe Machine Parameters (SMP) system are central to the protection of the Large Hadron Collider (LHC) machine. The BIS has been critical for the safe operation of LHC from the first day of operation. It has been installed and commissioned, only minor enhancements are required in order to accommodate all future LHC machine protection requirements. At...

7. Collimators and beam cleaning: first results and future plans

Chiara Bracco (Ecole Polytechnique Federale Lausanne (EPFL))

20/01/2010, 09:15

The LHC collimation system has been used for beam cleaning and passive machine protection this year for the first time. The hardware commissioning tests carried out in preparation for operations with beam are presented. Setup procedure towards nominal injection settings is analyzed together with reproducibility and total beam time spent for collimator setup. Locations of beam losses are...

9. Beam Dump Systems and Abort Gap Cleaning

Dr Jan Uythoven (CERN)

20/01/2010, 09:35

The performance of the beam dumping systems and the abort gap cleaning are reviewed in the context of the general machine protection system. Details of the commissioning experience and setting up, encountered equipment problems, the experience with and status of the eXternal Post Operational Checks (XPOC) and the importance of operational procedures are presented for the beam dumping system....

10. Injection and dump protection

Wolfgang BARTMANN

20/01/2010, 09:50

Results will be shown from the low-intensity beam commissioning of first, the moveable injection protection devices in the SPS to LHC transfer lines and downstream of the LHC injection kicker and second, the LHC dump protection elements in IR6. The implications of these results and a commissioning status report with the further planning will be addressed.

18. Overall MP and operation and scaling to 2010

Dr Jorg Wenninger (CERN)

20/01/2010, 10:10

Performance, measurements vs. expectations, problems encountered, is related software sufficient, necessary improvements, appropriate for 3.5TeV running?

11. General discussion

20/01/2010, 10:30

More feedback from operational experience- What can be improved?
