14:00 → 17:30 Session 2: Re-commissioning and Testing the Equipment

Aim of the session is to provide information and to give a summary of the most important commissioning and test activities for the CCC & linked systems and all machines that were not running in 2005. This covers the so-called “hardware test phase” from end of installations and modifications up to the cold-check out of the machines. All beam related aspects are covered in Session 3.

14:00 CCC Commissioning

The civil engineering of the CCC building is finished; the furniture and racks have been installed and equipped with computers and servers. The testing of these equipments has started and the room will be handed over to Operations in February. Here we present the schedule for the commissioning of the control room, its communications systems, the access control systems for the room and for the radioactive zones, and for the control systems of the accelerators, technical infrastructure and cryogenics.

14:30 Specific safety Issues for 2006 compared to 2004

Safety Requirements due to installation activities taking place in parallel with commissioning: PS Inflector Zone, LEIR Commissioning. Ionizing Radiation Hazards: Operational dosimeters, PS Bridge Closure. Oxygen Deficiency Hazards: SPS Transfer Tunnels and LHC Cold Tests, Oxymeters, Level 4 Courses. Handling Hazards: Loading/Unloading places. Reserved corridors for load handling with cranes.

Speaker: Paolo CENNINI (CERN)

14:45 Discussion

14:50 Access and safety systems – modifications and tests

This talk will present the changes resulting from the move from the MCR to the CCC for the PS access control system and the displacement of the SPS access consoles in to the CCC respectively. The PS access system has been modified to be able to operate with a console located 4 km’s away. A project to upgrade and replace the PS secondary areas access control has been launched. The same system will be also used for the SPS Experimental areas access control system upgrade. The SPS access system itself will not be modified for the 2006 runs but a number of compensatory measures will have to be added in order to comply with the INB status of the facility. These compensatory measures range from more limited access opportunities to more stringent patrol procedures to a much stricter enforcement of the use of emergency exits. The compensatory measures will later be followed by a major upgrade of the SPS access system and certain preparations for this upgrade will have to be made during 2006. A brief overview of the functional tests and validations planned for both the PS and SPS systems to ensure that they work as expected after the various modifications will also be given.

15:40 PS hardware tests

After the extended shutdown of 2005/6 there has been extensive work on the PS Ring, which will require some special start-up and testing. Mentioned will be the changes to the layout of elements in the straight sections, the main magnet units which have been revised and the auxiliary magnets which after many years of disuse have finally been purged from the machine. I shall present the tests to be done and the planning of the test period, with special mention of the MPS tests and how we will arrange the tests around EJP. The Kickers, Bumpers and Septa tests will also be included as well as the bake-outs required. The tunnel access conditions required for the test and how we shall do tunnel sharing for the remaining outstanding installation work. The modifications to the TT2 line and the tests required. machine tests

16:10 SPS hardware tests

Following the particular extended shutdown of 2004/2005, the main activities on the SPS machine will be presented, focusing on the few activities which could impact on a "standard" restart. A simplified planning shall be presented, underlining the overlap time period during which the hardware tests will be carried out in parallel with the completion of some installation activities. Finally, the access to the SPS machine during this particular test period and the link to the future INB rules shall be briefly described. systems

16:40 Experimental Areas hardware tests

The startup of 2006 will find the SPS beam lines with renovated hardware and control software. The hardware renovation includes a major part of the beam instrumentation, the access system, the vacuum and possibly the magnet control. The new control software is built in unison with the control software for the accelerators thus marking the end of NODAL era for the secondary beams. A first Dry Run (all but the beam!) was conducted in November 2005 where the “commissioning” of two beam lines was successfully tested, while a second one is scheduled for February 2006. For the PS East Hall, apart from the exchange of few magnets no other modifications to the lines or experimental areas are foreseen. Finally concerning the AD experimental areas the possible changes will depend on the recommendations from SPSC on the proposed and planned experiments. The major issues of all the above will be briefly presented.

08:30 Restart and maintenance of the B-train measurements for the PS Complex and the SPS

The responsibility of the Btrain measuring equipment and analog electronics will be taken over by AT-MTM from the accelerator cold check-out in 2006. The transfer of knowledge from AB-PO to AT-MTM has already taken place with the successful commissioning of the LEIR Btrain. The talk will address the issues related to the maintenance of all B-train systems. The interface with the associated real time software level will also be discussed. The planning for the start-up of the B-train systems for 2006 will be presented.

08:55 Recommissioning of Linac2/PSB/ISOLDE from CCC

In 2006, the Linac2, PS Booster and ISOLDE facilities will be re-started from the CCC. While these machines have been running in 2005, and no major hardware changes are planned for the 2005/2006 shutdown, the main challenge will be the full remote operation without the possibility of quick local interventions by the operator. As for the Linac2 and PSB, work has been done to identify and upgrade equipment that is not compatible with this way of running. Concerning the ISOLDE facility, operation will be similar to previous years relying very much on local interventions and direct contact to the users. The main changes of operation from the CCC will be highlighted and a tentative planning for the start-up will be presented.

09:35 PS and East Area re-commissioning with beam from the CCC after a 17 month shut-down

The PS and the East Area experimental zone will be re-commissioned with beam starting on April 8th, 2006. The first beam from PS should then be delivered to the SPS on May 15th. For a ‘normal’ start-up these four weeks should be much more than sufficient. However, the 2006 start-up is far from ‘normal’ and could even be called a ‘challenge’. During the 17 month shutdown between November 2004 and April 2006 many things have been changed and worked on. This presentation tries to give an overview of the implications of all these changes on the start-up. It will address points that need special attention, like for example the impact on the beam performance of the 20 renovated PS main magnets, but also what it means to operate from the CCC. It is also a request for support from the different groups to complete this ‘challenge’ as efficient as possible in the given time. At the end of the presentation a preliminary ‘start-up with beam planning’ will be presented for discussion.

10:45 AD and AD experimental areas: equipment tests and startup with beam

After 18 months of shutdown, the AD and its experimental areas will be re-started in essentially the same configuration as in 2004. Before starting up with beam, a comprehensive test of all AD equipment as well as a cold check-out will be required. This talk will deal with issues concerning the startup planning such as access, beam requirements, status of AD sub-systems and AD modifications. Emphasis will be given to specific problems related to startup and operation from the CCC vs. Local Control Room..

11:00 Discussion

11:10 Recommissioning the SPS and the North area from CCC

Experience tells us that the main ingredient for a successful start up of the SPS is a thorough and well conducted cold check out. Neverteless, the behaviour of certain equipment can only be checked with beam. The number of hardware and software modifications, implemented during a more than one year’s shutdown, imply an extended check-out with and without beam. The classical features to be checked with beam are the alignment and the aperture of the machine, as well as the low level RF. After a long shut down a few more iterations with beam measurements can be necessary in order to find a healthy and clean accelerator. The start-up with beam will have to be performed with new consoles, new software, modified orbit pickups, modified timing and modified interlocks. Parts of all this can only be tested with beam.
