On the threshold of new territory
Rolf Heuer on the physics potential of the LHC's first long run
Waiting for collisions in the LHC... Image: CERN |
With stable beams regularly circulating and colliding in the LHC, we have started the physics programme at 7 TeV. At a recent workshop in Italy, participants had the chance to take stock of what lies in store for the LHC's first physics run.

ILC Page 1
What would a central machine operations web page for the ILC look like?
A screenshot of LHC Page 1 — the ILC version could look rather different. |
On days when the LHC makes front page news, some web pages get more attention than they usually do. A page that is highly frequented by LHC operators, on display in all control rooms and a favourite link for physicists, but otherwise not all that well known, is LHC Page 1 (aka OP Vistars). One quick look gives you all the important information on the status of the machine. ILC NewsLine wanted to find out: what would an ILC Page 1 look like?

Celebrating first 7-TeV collisions at the LHC
All four LHC experiments saw collisions on 30 March, when 3.5-TeV beams collided for the first time. Image: CERN |
This past week marked the beginning of a new era for particle physics with the much publicised achievement of establishing the first 7-TeV collisions at the CERN Large Hadron Collider (LHC). Both the impressive performance of the accelerator and the fact that the detectors are in an advanced state of readiness bode very well for the early physics research programme. We should soon begin to have a glimpse of Terascale physics from searches for the origin of mass to looking for evidence of a new symmetry in nature that could even explain the dark matter. Even more intriguing is the real possibility for totally unexpected surprises that are awaiting us. We are looking to LHC science to establish what kind of lepton collider will be needed to best exploit the energy frontier in the longer term.

Leaving seminar rooms behind
Two weeks ago, project manager Nick Walker said in his guest Director's Corner that after planning the collider of the future in windowless seminar rooms in Beijing, he had one opportunity to see the Great Wall of China. This photo proves that he did not miss it — and strongly calls for another meeting in Beijing under more favourable weather conditions...
