    The coordination for the Hardware Commissioning (HC) activities will involve the handling of a large quantity of documents (test sequences and procedures, technical notes, schedules, test results, etc) which must be related to both the hardware baseline databases and the general planning files. This talk will describe the main ideas on how all the information related to the...

    The installation and commissioning of the LHC will produce a huge amount of data that will be collected and stored on different system databases. The MTF will bring together subsets of these data considered to be relevant for the traceability of test results during hardware commissioning. The talk will describe the interfaces between system databases and the MTF for the Electrical...

    The installation of the LHC control system hardware is a major step to be completed before the start of the LHC hardware commissioning phase. The control of the core LHC systems involved during hardware commissioning (power converters, power interlock system, quench protection system) requires in practice the full installation of most of the LHC control system hardware and associated...

    Applications for LHC hardware commissioning are being built as part of the development effort put in place since 2002 for the LHC era applications. For classic operations, like Power Converters controls, we aim to reuse the software developed for TI8. At the same time a huge effort is underway to introduce new industrial controls for the supervision of several important systems like...

    The prerequisite, requirements and constraints for a sector cool-down will be reminded. The different phases of cool-down, commissioning and operation for magnet powering will be reviewed with particular emphasis on what will be tested or verified for the first time (i.e. tests which could not be performed on String 1 & 2 and tests on equipments which are commissioned for the first...

    This talk will address the current status of the controls for the LHC, the schedule for the procurement of the tunnel electronics and control logic, the tasks associated with both the QRL reception test and the full LHC sector commissioning, and will give some comments on the feasibility with respect to the official LHC schedule. The cryogenic instrumentation and controls are...

    The DFBs, DSLs and connection cryostat, once installed and connected, form an integral part of the magnet powering scheme as well as the cryogenic system. This is reflected in the hardware commissioning. The test activities comprise: pressure and leak tests, high voltage tests (warm, before and after connecting and cold), instrumentation checks, control procedure validation...

    Hardware commissioning of the magnet systems comprises the test of its individual components as much as their interaction within the system. Only the latter operation shall be addressed in the Hardware Commissioning Review. The tests of the magnets are therefore discussed as a pre-requisite. On this basis, their initial state is defined and shall be taken into account for the...

    The basic problems in operating electrical circuits containing superconducting elements and the essential safety issues are recalled. There from, the relative importance of the various safety- related components are deduced and their impact on the schedule and operation, in case of failure, explained.

    The various steps of electrical quality assurance prior and during the powering tests will be discussed. Possible interference with the individual system tests of the quench protection and energy extraction system will be addressed. After a short review of the individual system tests prior to hardware commissioning, the test programme required for the proper qualification of the...

    The main topic of this talk is the validation of the warm part of the electrical circuit (power converters and DC cables) before powering tests with the magnets. In the first part, reception tests and installation of equipments are presented: reception tests of power converters in surface halls, installation of the power converters, installation and initial tests of the DC cables....

    On reception of the hardware for each Warm Magnet Interlock Controller (WIC) installation, the system will be constructed in the lab. This will facilitate testing of the hardware and the correct operation of the systems software and functionality. All input signals will be stimulated and the expected response of the system and the output for the respective power converter can then be...

    Before installation in the tunnel, the powering interlock controller (PIC) will be completely assembled and tested on all its functionality on the surface. One powering subsector in the tunnel will be managed by one dedicated powering interlock controller (two in the case of the long arc cryostat). For this, a dedicated test system is able to emulate all signals that the later on...

    The main topic of the talk is the validation for operation of the electrical circuits as a single system. In the light of the previous talks and the hardware commissioning documentation, each step of the powering tests will be revisited and their time durations justified. Risks, failure scenarios, and foreseen fall back solutions will be presented. The requirements and priorities for...

    The Beam Interlock System (BIS) forms the backbone of the LHC Machine Protection System, allowing 100’s of distributed User Systems to inhibit beam operation and request Beam Dump from all around the LHC. he requirement for rapid response time of the BIS is coupled with very high safety constraints, as whilst providing a secure and robust protection. The system should not be a source...

    Installation of the various accelerator equipment will begin shortly. It is based on a very tight schedule. In order to be ready for hardware commissioning many basic equipment tests will have to be done during this installation period, such as cabling, basic hardware operation and some of the power tests. Those will all be done under the responsibility of the corresponding...

    The “proper” hardware commissioning will start once the machine and experimental elements in the tunnel are installed and the individual systems tests are done, in both sectors around an even point. This implies co-activities between the two phases; as for example individual systems tests (such as short circuit tests, etc.) will be done during the installation phase without...
