Post Mortem will be the key to mastering the full complexity of LHC Operation and the interaction between systems. Many systems will be involved in full optimisation and understanding of performance. Today a few systems are providing data to validate and understand hardware commissioning. This must be extended giving priority to obtaining essential information related to...

15. Beam Instrumentation

Stephane Bart Pedersen (CERN)

The key beam instruments for post-mortem diagnostics in the LHC include:
• the beam position monitors (BPM), • the beam loss monitors (BLM), • the beam current transformers (BCT), • the non-destructive beam profile monitors, • the tune measurement, • the abort gap monitors. Turn by turn (or highest time resolution) data will be provided for all systems...

17. R.F.

Dr Andrew Butterworth (CERN)

The RF acceleration (ACS) and transverse damper (ADT) systems will supply post-mortem data at various acquisition rates. The PLCs controlling the power systems acquire at a few Hz, while high-speed digitizers and acquisition buffers embedded in the low- level hardware acquire transient signals at 80 MSamples/s over time periods ranging from a few milliseconds to several hundred...

18. Kickers

Etienne Carlier (CERN)

17/01/2007, 15:05

Reliable operation of LHC injection, tune/aperture and LBDS kicker systems relies on continuous on-line and off-line surveillances of their critical operational characteristics. Different acquisition techniques like trends logging, shot-by-shot logging or fast transient recording will be used to acquire and record the diverse types of signals existing within kicker systems....

16. Collimators and movable objects

The LHC collimation system is responsible for providing clean beam conditions and hence to assure the protection the equipment in the LHC. A failure of the collimation system may trigger a beam dump to avoid magnet quenches. The post mortem data of the collimation system supplies the following information • Demanded and actual positions of all collimator jaws (millisecond...
