Sergei Denisov elected academician by Russian Academy of Sciences
Sergei Denisov, long term Fermilab collaborator and leader of the Russian groups in the DZero collaboration, was recently elected as an academician of the Russian Academy of Sciences (RAS). He is one of about 100 electees, world-wide.
For more information, please visit the RAS website. Please be aware that it is only available in Russian.
Cedar Block visits Fermilab
Cedar Block, a Milwaukee-based ensemble, will perform a variety show titled, "Sexy Results," on Saturday, Feb. 18 at the Turner Hall Ballroom. The show tells the story of, "one man's love of science, the trash-talking particle accelerator that broke his heart, and the much theorized, but we-don't-know-for-certain-it-actually-exists Higgs Boson particle that will answer the Big Question - that's right - Life, The Universe and Everything." As part of the group's preparation, they spent a day visiting with scientists at Fermilab. Check out the above video or click here to learn more.
Fermilab scientist emeriti
Several scientists, retired from Fermilab, received the title of scientist emeritus. It's a status of honor granted in the recognition of the scientist's contributions to the laboratory over his or her career. They are all invited to continue scientific connections with the laboratory, and they each belong to a division or center and may receive Fermilab resources as appropriate.
To initiate the appointment process, scientists must discuss emeritus status with their division or section head, who may then recommend the status to the Directorate. The Directorate may then recommend the appointment to the board, summarizing the candidate’s career accomplishments and major contributions to the laboratory.

Advancing superconducting accelerating technology
A report from the TESLA Technology Collaboration meeting and the ILC-GDE SCRF meeting held in China last month
TESLA, which stands for TeV-Energy Superconducting Linear Accelerator, is the name of a former planned collider using an accelerating technology closely linked with the ILC. To some extent, TESLA can be said to be the predecessor of ILC technology. As time has gone by, TESLA technology has expanded its meaning to include superconducting radiofrequency (SCRF) advances and related accelerator studies across a broad diversity of scientific applications. Last month, from 5 to 8 December, the biannual TESLA Technology Collaboration (TTC) meeting, hosted by the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences together with Peking University and Tsinghua University, was held at IHEP in Beijing. About 100 experts around the world in accelerator field participated.
“The mission of the TTC meeting is to keep open and provide a bridge for communication and sharing of ideas, developments, and testing across associated projects,” said Jie Gao, chair of the Asian Linear Collider Steering Committee and chair of local organising committee.
From Nature, Jan. 5, 2012
Five experiments as hard as finding the Higgs.
As the media spotlight shines on the Large Hadron Collider in Geneva and its high-profile hunt for a certain boson, other scientists are pressing forward with experiments that are just as challenging — and just as potentially transformative.
These often unsung researchers are willing to spend years or even decades getting a finicky instrument to run smoothly; setting up proper controls to minimize spurious results; beating back noise that threatens to swamp their signal; and striving for an ever more painstaking level of precision — a determination and single-mindedness that borders on heroic. Here, Nature describes five such quests.
Spotting distant signs of life
Back in 1999, when David Charbonneau was a graduate student at Harvard University in Cambridge, Massachusetts, he became the first person to measure the tiny dimming caused by the passage of a planet from another solar system across the face of its parent star. Today, such 'transits' are a routine way for astronomers to discover planets.
The year 2011 was a banner year for CMS, as was described in a recent CMS Result. In a single year, the LHC delivered half as much data as the Tevatron did over a full decade. We announced incredible new insights on the mass of the Higgs boson. World-class limits on new physics ideas involving supersymmetry and hypothetical objects smaller than quarks ensures that the research program at the LHC will be an exciting and vibrant one for the next decade.
So what will 2012 bring? If the LHC performs as expected, we can anticipate recording a lot more data than we have so far. However, several decisions need to be made. Originally, the LHC was designed to run at a collision energy of 14 TeV, but a soldering failure in 2008 stopped operations for a year and a half. Pending an extensive reconfiguration of the electrical connections of the entire accelerator, the LHC began operations in 2010 at half the design energy, guaranteeing stable and reliable performance. It was at this 7 TeV collision energy that the experiments’ have achieved their successes of the last year. However, with a solid year of operations with intense beams, it seems that we might be able to safely push the collision energy up to 8 TeV in 2012. If this decision is made, it will increase the production of Standard Model Higgs bosons up 15 percent and will increase the discovery potential for very energetic new physics by as much as a factor of five.
In addition, the LHC was originally designed to collide proton beams every 25 nanoseconds. However, in 2011, the collisions were made to occur at a more leisurely 50 nanoseconds. A nanosecond is a billionth of a second, so leisurely is relative here. This pace is easier to achieve technically, but has the down-side of allowing more simultaneous collisions, which are harder to sort out.
In early February, senior representatives from the LHC and LHC experiments will present all of the options to the CERN Director Rolf-Dieter Heuer. The director will consider all the laboratory’s obligations and make a decision on how the LHC will operate in 2012: 7 vs. 8 TeV, 25 vs. 50 nanoseconds. The predicted amount of beam the experiments will receive in 2012 depend on these decisions, but a repeat of 2011 is essentially assured and an increase of 2-3 times is a possible, although aggressive, goal. Resumed collisions will commence in early March.
What discoveries will 2012 bring? That’s the tricky thing about discoveries. You have to find them first. Still, it is extremely likely that the Higgs boson situation will be definitively sorted out in 2012.
This year will end with a long, two-year, shutdown to undertake the modifications necessary to bring the LHC up to the design energy. The spring of 2015 will open up another frontier.
But first, we must mine the data recorded next year to search for every hint of discovery. With more data, a better understanding of the detector, and fresh new ideas, it seems likely that 2012 will show us that 2011 was just a warm up.
Some Fermilab site roads closed starting Jan. 9
Some roads on site will be closed from Jan. 9 through March 19. With the road closures, crews can maintain the same level of service in critical areas of the site. North Eola Road from Batavia Road to C Road East and Wilson Road from McChesney to B Road will be closed for the winter. In addition, Main Ring Road will be closed to all travel except for emergency and service vehicles. Limited snow removal service in the Main Ring will only provide access for these vehicles. Service levels and access will not change in the F4/A0 and C0 areas.
