In Brief

Two meetings on forming international Long-Baseline Neutrino Facility collaboration

The Fermilab directorate invites all principal investigators to participate in one of two meetings on the proposed Long-Baseline Neutrino Facility (LBNF), to be hosted by Fermilab. 

The first meeting takes place at CERN on Dec. 5 from 1-6 p.m. local time. The second meeting takes place at Fermilab on Dec. 12 from 10 a.m.-3 p.m. local time. Both meetings will have identical agendas and will be used to inform the community of the proposed experiment.

An LBNF collaboration-forming process began this summer with the establishment of an interim International Executive Board, which drafted a letter of intent. The letter of intent provides the basis for forming an international collaboration around LBNF.

Meeting attendees will discuss the letter of intent with the goal of developing an international collaboration of scientists interested in taking advantage of LBNF here at Fermilab.

Additional information about the meetings will be available soon. Please see the Fermilab directorate's full memo on these meetings.

Special Announcement

Wilson Hall closed Nov. 8-9 for maintenance

Wilson Hall will be closed for maintenance on Saturday, Nov. 8, and Sunday, Nov. 9, and power to the building will be shut off. Please turn off all electronics before leaving on Friday.

The Fermilab site will still be open to the public from 8 a.m. to 8 p.m., but Wilson Hall will be locked.

Where the hunt for missing antimatter and new physics are one and the same

From Motherboard, Nov. 1, 2014

One of the cosmos' most elusive mysteries may be a bit closer to an explanation with new analysis of a highly odd particle produced at the Large Hadron Collider. The mystery: What happened to the universe's vanished share of antimatter? The particle: the Bs meson, an extremely short-lived pairing of two quarks capable of changing identities between matter and antimatter some three million million times per second.

Vanishing dark matter points to a dark future for our universe

From Gizmag, Nov. 4, 2014

A study conducted at the University of Rome and the University of Portsmouth is suggesting that the amount of dark matter in the cosmos, the catalyst that facilitates the creation of new stars and galaxies, is decreasing as it interacts with dark energy. If this is true it would mean that, as time passes, the Universe could be destined to end up a desolate and nearly featureless place (even more so than it already is).

Obituary: Tullio Regge

From Società Italiana di Relatività Generale e Fisica della Gravitazione, October 2014

Tullio Regge passed away a few days ago. One of the most brilliant and most creative minds of the XX century has left the world stage after a long physical decline that was cause of deep sorrow for all of his friends, colleagues, former co-workers and, of course, relatives. The influence of his ideas and the legacy of his imaginative physical-mathematical constructions will stay with us for ever. New generation scientists, sometimes not even aware of that, will develop constructions whose very conception would be unconceivable without Regge's creations. Those who knew Tullio personally, those who interacted with him both scientifically and/or in other human and cultural activities, will never forget his very original, multi-faced and intriguing personality.

Multilaboratory collaboration brings new X-ray detector to light

A collaboration blending research in DOE's offices of High-Energy Physics (HEP) with Basic Energy Sciences (BES) will yield a one-of-a-kind X-ray detector. The device boasts Brookhaven Lab sensors mounted on Fermilab integrated circuits linked to Argonne Lab data acquisition systems. It will be used at Brookhaven's National Synchrotron Light Source II and Argonne's Advanced Photon Source. Lead scientists Peter Siddons, Grzegorz Deptuch and Robert Bradford represent the three laboratories.

"This partnership between HEP and BES has been a fruitful collaboration, advancing detector technology for both fields," said Brookhaven's Peter Siddons.

This detector is filling a need in the X-ray correlation spectroscopy (XCS) community, which has been longing for a detector that can capture dynamic processes in samples with microsecond timing and nanoscale sensitivity. Available detectors have been designed largely for X-ray diffraction crystallography and are incapable of performing on this time scale.

In 2006, Fermilab's Ray Yarema began investigating 3-D integrated chip technology, which increases circuit density, performance and functionality by vertically stacking rather than laterally arranging silicon wafers. Then in 2008 Deptuch, a member of Yarema's group and Fermilab ASIC Group leader since 2011, met with Siddons, a scientist at Brookhaven, at a medical imaging conference. They discussed applying 3-D technology to a new, custom detector project, which was later given the name VIPIC (vertically integrated photon imaging chip). Siddons was intrigued by the 3-D opportunities and has since taken the lead on leveraging Fermilab expertise toward the longstanding XCS problem. As a result, the development of the device at Fermilab — where 97 percent of research funds come through HEP — receives BES funding.

A 64-by-64-pixel VIPIC prototype tested at Argonne this summer flaunted three essential properties: timing resolution within one microsecond; continuous new-data acquisition with simultaneous old-data read-out; and selective transmission of only pixels containing data.

The results achieved with the prototype have attracted attention from the scientific community.

Deptuch noted that this partnership between BES and HEP reflects the collaborative nature of such efforts at the national labs.

"It truly is a cooperative effort, combining the expertise from three national laboratories toward one specific goal," he said.

The team will grow their first VIPIC prototype tiled, seamless array of chips on a sensor to form a 1-megapixel detector. The collaboration is targeting a completion date of 2017 for the basic functionality detector. Ideas for expanded capabilities are being discussed for the future.
