CERN Accelerating science

Dear Colleagues, dear Members of the EP Department, dear CERN Users,

We are in the middle of a fantastic year for CERN. After a difficult restart the LHC experiments are now taking data in full swing...

A new energy frontier for heavy ions

by John Jowett

This week, just under three decades since the Tevatron reached 1 TeV, the LHC resumed its programme of colliding so-called "heavy ions", reaching 1045 TeV in the collisions, breaking the symbolic barrier of a quadrillion electron-volts, or 1 PeV...

Exit protons, enter ions

by Federico Ronchetti

The 2015 LHC proton run, the first after the long shutdown 1, ended last week with a good performance of the accelerator given the challenges of running at the new collision energy of 13 TeV. 

First Pb beam in NA61/SHINE

by Antoni Aduszkiewicz

December 1st ended a two-week test period with Pb beam in the NA61/SHINE xed-target experiment. Pb ions at momentum of 30A GeV/c were delivered from the CERN SPS to the experiment for the first time. 

Last May, the PH newsletter reported about the two-month pilot run of 2014 and how NA62 was preparing for the 2015 data taking:  this became reality for five months between mid-June and mid-November, an exciting but exhausting period for our operation team!

At their 4th Collaboration meeting on the 10th and 11th of December the MoEDAL Collaboration looked back over a successful year. MoEDAL is a pioneering experiment designed to search for highly ionizing avatars of new physics such as magnetic monopoles or massive (pseudo-)stable charged particles.

The last edition of this letter at the end of 2014 ended with the optimistic remark that CMS after the end of LS1 would be perfectly prepared for the exciting times ahead of us. And indeed the final steps of LS1 went smoothly with CMS ready for the first beams. 

A successful year for the LHCb collaboration

by Patrick Robbe

After the Long Shutdown 1, the LHCb experiment started data taking during this year both during the proton-proton collisions at 13 TeV but also for the first time during the heavy-ion run.

Chronicles of the ATLAS data taking in 2015

by Alessandro Polini

ATLAS undergone an intense programme of upgrade and maintenance preparing for the Run 2 proton collisions at the previously unattained energy of 13 TeV. 

An interview with Dr. Georg Bednorz

by Panos Charitos

Superconductivity remains one of the most fascinating manifestations of the laws of physics. We met Georg Bednorz, who together with K Alex Müller, discovered the high-temperature superconductivity in ceramics; a discovery for which they shared the Nobel Prize in Physics in 1987.

FCC-hh baseline layout and parameter set

by Daniel Schulte (CERN) with Alexandra Welsch (UNILIV)

A team of experts from collaborating institutes work under the study for a Future Circular Collider (FCC) on the parameters of hadron-hadron collider. They have recently reached the first important milestone at the end of September: a baseline for the machine layout and the main parameters of this collider.

The Straw Detector in the NA62 Experiment

by Hans Danielsson

In NA62, the straw tracker is designed to measure the momentum and direction of charged tracks.The design of the NA62 straw tracker was driven by the requirement of low multiple scattering and high efficiency over the full acceptance. 

End of year activities in SFT group

by G. Cosmo, G.Ganis, S. Gleyzer, J.Harvey, A. Naumann

The end of year is traditionally the time when SFT makes new releases of our main software products. It is a very busy time with everyone working energetically to meet various deadlines. All last minute changes and fixes need to be integrated and run through extensive checks to ensure that quality of the performance of the code.

One of PH/ESE’s flagship projects is the Radiation Hard Optical Link project for LHC, a common development for all LHC experiments and other interested collaborations. 

Thank You!

by Rolf Heuer

This is my last message to CERN personnel as Director-General, and the overriding sentiment I’d like to pass on is ‘thank you’: it has been a fantastic seven years. I’ve been privileged to be DG through amazing times, and thanks to the efforts of many we are at the threshold of a golden era for our field.
