From CERN: CERN management confirms new LHC restart schedule

Geneva, 9 February 2009. CERN management today confirmed the restart schedule for the Large Hadron Collider (LHC) resulting from the recommendations from last week’s Chamonix workshop. The new schedule foresees first beams in the LHC at the end of September this year, with collisions following in late October. A short technical stop has also been foreseen over the Christmas period. The LHC will then run through to autumn next year, ensuring that the experiments have adequate data to carry out their first new physics analyses and have results to announce in 2010. The new schedule also permits the possible collisions of lead ions in 2010.

Digging deep
Conventional facilities crew hooks up with European XFEL experts
Thomas Hott (centre) explains the set-up of the future XFEL accelerator tunnel in a life-size mock-up on the DESY campus. |
The small town of Schenefeld just outside Hamburg in northern Germany isn't exactly known for its sights or its tourism. Many Schenefeld citizens, however, have recently become tourists in their own neighbourhood: ever since the construction works for the European XFEL started on 8 January, the building site sees a steady flow of visitors stopping by on or from their way to the shops, checking on progress, curious about their new neighbour. While the whole ILC project can learn a lot from this curiosity (namely establishing good contact with neighbours when construction for the collider starts), one specific group is digging deeper: the 'conventional facilities and siting (CF&S)' team is establishing close contacts to experts working on the European XFEL to learn from them and to help when possible.

Cern: le redémarrage de l'accélérateur de particules LHC à nouveau reporté
Cette nouvelle date a été jugée "prudente" par M. Heuer, car elle permet d'assurer "que tous les travaux nécessaires ont été faits sur le LHC avant qu'il ne redémarre. De plus, elle permet "de commencer les recherches physiques cette année", a-t-il ajouté.

Involving Spain in the ILC R&D programme
Juan Fuster, Chairman of the Spanish Particle Physics National Programme |
We had a nearly two-day meeting with the Spanish particle physics groups to explore collaborations for the ILC last month, immediately following the Funding Agencies for Large Colliders (FALC) meeting in Madrid. During the FALC meeting, Juan A. Fuster Verdú gave an overview of the particle physics programme in Spain, and we had more detailed discussions of the programme and possible collaborations the next two days. These meetings gave us a much better understanding of the capabilities and ambitions of the Spanish groups and gave them a better picture of the opportunities in ILC R&D and design work. We expect to continue these productive discussions, leading up to increased Spanish involvement in the ILC.

Close-up view of a TPC cathode
This copper-clad aluminium cathode used in a Time Projection Chamber (TPC) is patterned with little holes and lines. When the pattern is illuminated with a laser light, the distribution of the emerged electrons – coming from the aluminised areas, provides an instrument to observe irregularities in the electric and the magnetic fields embedding the TPC.
