Puzzling asymmetries

In a recently published paper, the LHCb Collaboration has reported on a possible deviation from the Standard Model. Theorists are now working to calculate precisely this effect and to evaluate the implications that such unexpected result could have on the established theory. >>

Two beautiful new particles

In beautiful agreement with the Standard Model, two new excited states (see below) of the Λb beauty particle have just been observed by the LHCb Collaboration. Similarly to protons and neutrons, Λb is composed of three quarks. In the Λb’s case, these are up, down and… beauty. >>

Life after discovery: a look at the SPS of 2012

Though no longer the newest kid on the block, the SPS remains as essential to CERN’s research programme as it was when it discovered the W and Z bosons back in 1983. The CERN Bulletin takes a look at how the SPS has kept up with younger CERN accelerators... >>

How are we behaving?

It’s almost two years since CERN introduced a Code of Conduct. The results may not be immediately measurable, but I’d like to think it’s made the lab a better place to be. The Code of Conduct is based on values that most of us immediately identify with, and so implementing it comes as second nature. Nevertheless, in an organisation of over 10,000 people, it’s useful to have a set of guidelines and there have been occasions on which it’s been necessary to remind people of them. >>

LHC Report: Rocky re-start

A rocky re-start with beam followed a successful machine development period and the first technical stop of 2012. Today, Friday 11 May, the machine began running again with 1380 bunches. >>

Computing power on the move

You might sit right next to your computer as you work, use the GRID’s computing power sitting in another part of the world or share CPU time with the Cloud: actual and virtual machines communicate and exchange information, and the place where they are located is a detail of only marginal importance. CERN’s new remote computer centre will open in Hungary in 2013. >>

CERN openlab enters new phase

The newest phase of CERN’s openlab framework was inaugurated this week during a meeting of the openlab partners. This phase will last three years and will bring together existing openlab partners and a new contributor: Huawei. >>

Tailor-made training for digital library software

Six librarians and IT engineers from Senegal, Mali, Burkina Faso, Ivory Coast and Morocco are currently spending several weeks at CERN as a follow-up to the 5-day CERN-UNESCO Digital Libraries School held in Dakar, Senegal, last year. During their stay, they are honing their mastery of CERN’s Invenio digital library management platform in order to put it to a variety of uses once they return home. >>

A Monte Carlo code for ion beam therapy

Initially developed for applications in detector and accelerator physics, the modern Fluka Monte Carlo code is now used in many different areas of nuclear science. Over the last 25 years, the code has evolved to include new features, such as ion beam simulations. Given the growing use of these beams in cancer treatment, Fluka simulations are being used to design treatment plans in several hadron-therapy centres in Europe. >>

ARDENT to develop advanced dosimetric techniques

Earlier this week, the EU-supported Marie Curie training network ARDENT kicked off at a meeting held at CERN. The overall aim of the project is the development of advanced instrumentation for radiation dosimetry. The applications range from radiation measurements around particle accelerators, onboard commercial flights and in space, to the characterization of radioactive waste and medicine, where accurate dosimetry is of vital importance. >>

Laser acceleration... now with added fibre

Laser acceleration technology is plagued by two main issues: efficiency and repetition rates. In other words, lasers consume too much power and cannot sustain accelerating particles long enough to produce collisions. ICAN, a new EU-funded project, is examining how fibre lasers may help physicists tackle these issues. >>

The European Nuclear Science network touches base at CERN

ENSAR (European Nuclear Science and Applications Research) is an EU-supported project, which aims at fostering cooperation within the European low-energy nuclear physics community through the active sharing of expertise and best practices. The project also includes a transnational access programme to allow a large community of users to access the participating facilities, which include CERN’s ISOLDE. In the last week of April, CERN hosted the General Assembly and Programme Coordination Committee meetings, about 18 months after the project’s kick-off. >>

Safety brings CERNois together

The World Day for Health and Safety at Work, which was celebrated at CERN on 27 April, provided an opportunity for the safety professionals and members of the CERN personnel to get together to discuss joint concerns. It was a good opportunity for people to learn to distinguish between good and bad habits. >>

Ready, set, move!

This year, the CERN Medical Service is launching a new public health campaign. Advertised by the catchphrase “Move! & Eat Better”, the particular aim of the campaign is to encourage people at CERN to take more regular exercise, of whatever kind. >>

Oxford engineering students to study new solutions for vacuum chambers

Train your brain: Don’t put your password on paper!

I completely acknowledge that constructing a good password can be difficult. And remembering it for some time isn’t easy, either. However, noting it down on a sheet of paper and hiding it in a drawer in your office (or even attaching a sticky note to your monitor) isn’t a valid solution. It violates CERN Computing Rules. >>

Ombud's corner: Use of sensemaking* in ethical decisions

In this series, the Bulletin aims to explain the role of the Ombuds at CERN by presenting practical examples of misunderstandings that could have been resolved by the Ombuds if he had been contacted earlier. Please note that, in all the situations we present, the names are fictitious and used only to improve clarity. >>

News from the Library: Online particle physics information: a unique compilation of information resources in particle physics

Are you looking for some specific information in particle physics? For example, the main literature databases, data repositories or laboratories... >>

C.J. “Kees” Zilverschoon (1923 - 2012)

C.J. was one of the first staff to join CERN, in May 1954 – when there was no laboratory and only the beginnings of an organization, which was formally founded in September 1954. Most people coming to CERN at that time left a well-established position at home, choosing (as J. B. Adams said in an interview) an ‘adventure against job safety’. >>

Piotr Doniec (1987-2012)

It is with great sadness that we learned about the tragic loss of our valued technical student and friend Piotr Doniec. He was taken from us on 29 April, at the age of 25, while following his passion for mountaineering during a descent in the French Alps, near Thônes. >>
