Ristori to take over as CDF

On June 1, Luciano Ristori takes over from Giovanni Punzi as CDF co-spokesperson, joining current co-spokesperson Rob Roser in the role. This will be Ristori's second time serving as a CDF spokesperson.

"Luciano is an ideal person to do this," Roser said. "He is a senior member of the collaboration and one of the founding members of the experiment. He understands the pitfalls, hurdles and challenges ahead and I am sure he will come up with creative solutions for them."

The experimental spokespersons serve a two-year term with alternating election years to ensure overlap between the terms.

The CDF team is in the final stages of its physics analyses. Ristori will help complete CDF's data and infrastructure setup so that future generations can mine its vast trove of data.

"CDF still has a lot to say," Ristori said. "We want to finish analyzing all the data and make sure that the Tevatron's legacy is not wasted."

It will be Ristori's job to motivate the scientists, continue CDF data analysis and preserve the data for the future.

"The Tevatron's data is special because it involved proton-antiproton collisions, whereas the LHC is proton-proton collisions," Ristori said. "I believe that there are measurements we can do with our data that will complement and help us understand what the LHC sees. Ten, fifteen, twenty years from now we might want to look back at it, but we can only do that if we preserve it in a way that will be accessible in the future."

With the Tevatron decommissioned and Fermilab's focus switching to future Intensity Frontier experiments, this term as CDF co-spokesperson is bittersweet. But Ristori is excited that he will be an integral part of preserving CDF's legacy and providing closure to the experiment.

"I've worked on this experiment for 30 of my 40 years as a scientist," Ristori said. "I feel grateful to CDF and Fermilab and I'm going to do my best to gracefully finish what needs to be done so we can close the door for good."

Particle physics: A reminder of the beauty we know

From Nature, May 23, 2012

The most precise measurement so far of the mass of the W boson is reported by researchers in the CDF Collaboration (Aaltonen et al.) at the Tevatron collider, Fermilab, near Chicago, in Physical Review Letters. The W boson is the particle that carries the weak nuclear force, which is responsible for radioactive β-decay. The particle decays in less than one billion-trillionth of a second, and many of the things that it decays to are hard to detect. The measurement of its mass is an experimental tour de force, a consistency test for the standard model of particle physics, and a pointer that will aid the discovery of new phenomena at the Large Hadron Collider (LHC) at CERN, Europe's particle-physics laboratory near Geneva, Switzerland.

The 'standard model' is the rather prosaic name given to the collection of quantum field theories that describes the Universe at the shortest distances and highest energies. You will often hear particle physicists hoping for physics 'beyond the standard model' because an anomalous experimental result might help to resolve some of the issues left unexplained by the model. These problems — including why the Universe contains more matter than antimatter, and where gravity fits in — are discussed so often that it is easy to forget how accurate and economical the standard model is.

DECam team celebrates completion of project

Brenna Flaugher, project manager for the Dark Energy Camera, wrote this week's column.

Brenna Flaugher

The construction, delivery and testing of the 570-megapixel Dark Energy Camera, led by Fermilab to study dark energy, is complete, on budget and on schedule. This is a big success and testament to the dedication and skills of the Fermilab staff and the collaborating institutions.

Over the past year we delivered all the pieces of the camera to our collaborators at the Cerro Tololo Inter-American Observatory in Chile and retested the systems after their arrival. The observatory is now in charge of the installation of the Dark Energy Camera on the telescope, which will be complete soon.

Under the leadership of Fermilab's Josh Frieman, the Dark Energy Survey collaboration is now moving toward operations. Planning for a first light celebration is in progress, with the likely date in early November.

The idea to build one of the largest digital cameras in the world at Fermilab began eight years ago. Under the direction of former Fermilab Director John Peoples, a collaboration was formed in 2004 for the design, construction and testing of the Dark Energy Camera. The experienced staff and the superb infrastructure of PPD's Silicon Detector Facility, developed for the construction of the silicon detectors for CDF, DZero and CMS, provided a strong base for building the camera. The Experimental Astrophysics Group in the Computing Division had gained extensive experience with the Sloan Digital Sky Survey. The Experimental Astrophysics Group and members of the Astrophysics Theory Group provided scientific leadership. Together, we successfully navigated the extensive review process that led us from concept to completion.

The collaboration and project management would like to thank the many groups at Fermilab who contributed to our success. PPD's Electrical Engineering Department faced particular challenges with the very-low-noise readout requirements. PPD's Mechanical Department developed a liquid-nitrogen cooling system that required innovative ideas to solve a number of challenges, and in Lab A the team constructed a full-sized replica of the top of the Blanco telescope to test the camera installation and operation. The skilled, technical support staff at PPD's Technical Centers produced more top-quality CCD assemblies from the sensors delivered by Berkeley Lab than we ever could have hoped for and provided the detailed measurements and alignment of the large support structures. Finally, PPD's budget office and project management support were essential to keep track of our progress and navigate through 14 comprehensive project reviews. Support from the Computing Division contributed to the development of the online data acquisition and controls systems and the Business Services Section provided guidance on many national and international contracts.

In just a few months we will be seeing the first images from DECam. With a 3-square-degree field of view, about eight times larger than the size of the moon as seen from Earth, we will start building the largest, deepest map of the southern sky and take the next steps towards constraining the nature of the mysterious dark energy that is blowing the universe apart.
