Eight-year-old Genevieve Steele was a little girl who knew what she wanted. And what she wanted was to play the harp. As soon as she first spotted one, while clog dancing at Sidmouth Folk Festival on England's south coast, she pretty much didn't let it out of her sight.

Maybe it snuck into her subconscious while she was wandering the geometrically perfect street plan of her native Euclid (yes, named after the famous 'Father of Geometry') near Cleveland, Ohio. Maybe it rubbed off on her as she discovered the intricacies of risk and probability while dealing smoky late night blackjack for her father's casino equipment hire business. Or maybe it was just pure chance. But one way or another, mathematics is in Kathy Copic's bones.

Going into his new position with Johannesburg's University of the Witwatersrand ('Wits' for short), Trevor Vickey sees his brief as “a sort of linear combination between a professorship and a Peace Corps assignment”. The tenure-track Senior Lecturer post will take him to a brand new continent, but, he says, he made the original application “on a whim” after five years as an ATLAS postdoc.

For most particle physicists, memories of the dim and distant past when they couldn't yet use a computer are distinctly fuzzy. For Mahsana Ahsan, though, they're a little fresher: “I didn't have a chance to use computers during my studies due to lack of computer labs,” she explains. “When I first went to the US, I was only able to type an email very slowly.”

“I‘m very outgoing,”says Lucie de Nooij, without hesitation.“That may be a Dutch thing, but it‘s also very much me.”

Although he was a self-professed ‘bookworm’ up until his PhD days at Panjab University, Nitesh Soni somehow never expected to become a research scientist. “I was actually preparing for the Indian Administrative Services exam,” he recalls, an essential step on the path to becoming a Police Commissioner or Deputy Commissioner. “So I just joined particle physics research for a second option. But then after four months, my supervisor sent me to Japan, which changed my life.”

As he munches on an all-American breakfast – fresh juice and a bagel hand-delivered by a friend from New York – Jim Degenhardt is the first to admit he’s not a morning person. It’s the aftermath of the 9 a.m. Run Meeting, a daily appointment for Jim as co-run coordinator of the TRT, but the NY-themed sustenance seems to be doing the trick.

It’s hardly a stretch of the imagination to think of ATLAS and CMS as siblings: competing, trying to get ahead, but ultimately friendly and supportive of each other. But for Germán Carrillo, the analogy moves over into the literal, because while he studies for a PhD on ATLAS, older brother Camillo is a six-year CMS devotee.

Thorsten Wengler can still remember exactly where he was when the Berlin wall fell in November 1989: on night guard, sitting atop a pile of arms and ammunition in the woods outside of Potsdam, Germany, alongside three of his fellow East German soldiers.

If a chance meeting hadn’t led Tapas Sarangi to a PhD in Japan, things could have been very different: “I would probably have been in the Indian Navy as a commissioned officer!” he admits.

Looking back, as he can now, from a position of maturity, Nabil Ghodbane is a little embarrassed about the scene that unfolded when he met Peter Higgs. “At the time, I was maybe a bit naïve,” he admits bashfully, as he recounts a tale of waiting outside the toilets after a Scottish summer school talk to greet Professor Higgs on his way out. “We were like groupies!” he laughs at himself and other students who stampeded the reluctant physics celebrity.

As an ATLAS physicist, it’s not often you get to stand back and look at the bigger picture, according to Richard Teuscher: “Not at all! It’s only really when you get a chance to talk to someone about what you’re doing. Day-to-day, you’re writing software or fixing some part of the detector. But at the end you think, ‘Wow, look what we’ve done!’"

Most people at CERN know Claudia Marcelloni as the ATLAS photographer and the exquisite eye behind the ATLAS book, Exploring the Mystery of Matter. But to Claudia, photography is just one tool that she could use to practice her passion: the creative communication of ideas.

For Jochen Schieck, monthly trips to CERN – often spanning just one day – suit him well. The rest of the time he’s based at the Max Planck Institute (MPI) of Physics in Munich.

Osamu Jinnouchi had never left his native Japan when he first came to CERN, as a summer student with KEK, aged 25. “I don’t quite remember, but it was all impressive,” he ponders. “Everything was different here.”

A new multimedia contest has been set up to put talented young filmmakers and science communicators in touch with ATLAS.

Harry Potter fans can probably sympathise with Helenka Przysiezniak Frey’s initial reaction to being profiled for e-News. “My husband tells me: do it,” she wrote in an email, but her latest reading material had left her with some reservations: “[The Harry Potter] equivalent of ATLAS e-News, the Daily Prophet, says all kinds of lies about Harry and co.”

Salsa, singing, sight-seeing and skiing are all high on the list of ways to relax and unwind for up-beat PhD student Laura González Silva. “Dancing, I loved it always. I try to go as often as I can,” she smiles. Back in her hometown of Buenos Aires, Laura was part of a choir too, but in Geneva her vocal talents are mainly consigned to karaoke bars or her shower. “Singing and dancing – they’re a part of me,” she grins. “I forget about everything. And it’s good after spending ten-hours-a-day in front of the computer!”

It was Santa Claus who first introduced TileCal data quality coordinator Andrea Dotti to “serious science”, when he was just 12 years old. “Since I was a small kid, I was more skilled in maths,” he explains. “I never liked to learn poems by heart, history was not my thing…” But the year Andrea received a chemistry set for Christmas he was immediately hooked, his interest fostered by a kind elderly pharmacist who sold him supplies.

ATLAS got a little taste of Tinseltown on February 12th, as director Ron Howard, and actors Tom Hanks and Ayelet Zurer rolled into town to promote their new film – an adaption of Dan Brown’s bestseller Angels and Demons.

Over Christmas, we followed the progress of ATLAS collaborator, Katharine Leney, as she and her boyfriend Pierre drove across Europe and Africa in a beaten up second hand car, to raise money for development charities working in Africa.

Physics, as a discipline, isn’t short of references to symmetry and balance. The tale of Anna and Lucia Di Ciaccio though is almost poetic in the way it weaves. They are non-identical twins, and interviewing them is both slightly surreal and a complete delight.

For SCT Project Leader, Pippa Wells, thoughts of precision, timing, collaborative working, and getting things to work in harmony are familiar to her both in and out of work. Her passion is playing the violin – specifically in orchestras. “It’s always been playing music with other people that has motivated me,” says Pippa, who picked up her first instrument when she was just six years old.

Zuzana Zajacova found her way to ATLAS through a slightly unusual route. Rather than being a particle physicist or engineer, she comes from a background of biomedical physics.

Talking to Steve Lloyd, you can’t help but get the sense that the influence of this softly spoken, polite Brit is woven into the very fabric of CERN. As the author of the improved ATLAS Computing Workbook, he has certainly touched the working lives of all new members of ATLAS since 2005, but his reach extends further than that.

Walk through Restaurant 1 at about 1 p.m. on a weekday, and you can’t fail to notice the plethora of languages being spoken. Not only that, the diversity of accents twisting themselves around English or French conversations reveals just how many nationalities are represented at CERN. Nevertheless, listening to Anthony Morley mid-flow is still a bit of a novelty, given that he’s one of only a handful of Australians working on-site on ATLAS.

Marc Dobson plays something of a lynchpin role at ATLAS; he’s one of those utterly essential people whose true value you only discover when things are going wrong and all Hell is breaking loose.

“I’ve always wanted to do it I guess,” considers ATLAS PhD student Kate Shaw. “It was probably books by Stephen Hawking, Roger Penrose… They inspired me to start with – to understand the fundamentals of the Universe.”

“Of course, at the very beginning, I had no idea how complex it would be. I think most people didn't. I thought it might take two or three years, but not almost six,” says Sergei Malyukov of the ATLAS cabling project which will finally reach its completion at the end of June. As Cabling Project Coordinator, Sergei has certainly had his hands full, both metaphorically and physically.

German Federal Chancellor Angela Merkel made a historic visit to CERN at the end of last month. During her brief 1.5 hours on site, she was taken on a whistle-stop tour of the ATLAS control room and cavern, and given the chance to look down on the largest particle physics experiment in the world from a dizzying height of 100 metres through the access shaft which links the massive underground cavern to the surface.

Polish-born PhD student Katarina Pajchel moved to Norway when she was very young. She studied physics in Bergen and went on to complete a Master’s degree there too, analysing DELPHI data coming off LEP. Now part of the University of Oslo’s experimental HEP group, she has spent the last three years involved in developing Grid computing for ATLAS.

They say there’s no such thing as bad publicity, but how would recent attempts in a Hawaiian court to stop the opening of the LHC because of safety concerns affect the general public’s perception of CERN? The Open Day on 5-6 April gave the ATLAS Collaboration a chance to find out.

Anyone working on the ATLAS experiment right now will agree that it is more than a full-time job. But Monica Dunford is not your average woman. On top of working on the Tile Calorimeter, helping to commission the Level-one Trigger, and coordinating Tile Cal’s operation running, she somehow finds the time and energy to row, ski, run marathons, and tell the world about life here at ATLAS.

Celebrations are underway in the ATLAS Experiment, as the final element of the detector was lowered into the cavern on Friday February 29th, 2008. The second “small wheel” is also the final part of the muon subsystem, but the wheels themselves are small in name only. At 9.3 metres in diameter, and weighing in at 100 tons each, moving them from their construction warehouse, at the north-west tip of the CERN site in Geneva, to the underground ATLAS cavern was a challenge which was anything but small.

We’ve all heard the story about the End Cap Toroid magnets having only a few centimetres clearance on either side as they were eased into place in the detector last year. Well, Tatiana Klioutchnikova and her colleagues are the ones to thank for that carefully controlled close-shave not ending up in a disastrous scrape.

Most ATLAS users know Emil Obreshkov only as a man at the end of a mysterious e-mail address. Ceri Perkins went along to meet the man himself, and find out a bit more about him.

The cables within the ATLAS detector may be thought of as the blood vessels and nervous system of the experiment; they carry power to the detector, they deliver messages to control its functions and they relay the data taken, ready for analysis. Just as blood vessels and nerves criss–cross and connect the organs and tissues of the human body, cables penetrate the whole of the ATLAS volume, reaching each and every one of its elements.

Dave Charlton and his team have a mammoth job on their hands; Charlton has been tasked with coordinating the Full Dress Rehearsal (FDR) of the computing and data analysis processes of the ATLAS experiment, a run–through which he describes as "essential, almost as much as ensuring the detector itself actually works".
