LARP Collaboration Meeting @LBL, April 26th 2006
The Commissioning of the Technical Systems of LHC
1. The final validation that all the collider components/systems perform as specified.
2. All the tests are performed without beam.
3. The sectors under test are fully installed but installation is going on in other sectors.
4. Also, tests are going on in other sectors.

Esther Barbero SotoDavide BozziniPaul CruikshankReiner DenzBruno PuccioFélix Rodríguez MateosRüdiger SchmidtLuigi SerioHugues ThiesenMarkus Zerlauth
This document describes the sequence of the steps which lead to the commissioning of the complete inner triplet. It gives the backbone of the general procedures and refers to more detailed documents associated to the different systems, which in turn describe the individual system tests and the hardware commissioning procedures.

Amalia Ballarino, Davide BozziniKnud Dahlerup-PetersenReiner Denz, Robin LaucknerBruno Puccio, Félix Rodríguez-Mateos Roberto Saban, Rüdiger SchmidtLuigi Serio, Hugues ThiesenAntonio Vergara, Markus Zerlauth
This document describes the sequence of the steps which lead to the powering of the superconducting circuits of a powering sub-sector to nominal current. It covers the phases after the connection of the power cables to the current leads up to the powering in unison of all the circuits of a sector to nominal current.

failure scenarios failure scenarios during the
commissioning were studied
the objective was to define strategies for at least a few case studies per major system in order to gain in reactivity at the time of failures
evaluate the impact on the program and
define alternatives to carry-on
six sessions of the HCWG were devoted to this study:
Superconducting Electrical Circuits Cooling and Ventilation System Cryogenic System Vacuum System & Leak Tests Electrical Power Distribution Power Interlock Controllers
