Adler Planetarium throws 'Particle Party'

Last week, three young physicists looked expectantly at an audience filling an auditorium at the Adler Planetarium in Chicago, waiting for the next question.
Everyone was there for Adler After Dark, a 21-and-up evening event held the third Thursday of each month to draw in a different crowd from the families and school groups that usually visit the planetarium. September's theme was "Particle Party," which brought physicists and educators together with a crowd of more than 1000 science enthusiasts, most in their 20s and 30s, over foggy drinks served with dry ice.
The physicists had given a presentation about the various types of particle physics research at Fermilab. Marcelle Soares-Santos, a member of an experiment seeking to understand the nature of dark energy, explained during her talk that about 5 percent of the universe is made up of visible matter—all of the rest is the more mysterious dark matter and dark energy.
"How distressing is it that we don't understand 95 percent of the universe?" a man in the audience asked.
Soares-Santos smiled. "I think the word we use is 'humbling,'" she said. "Also, for our generation, it's exciting."
Many of the guests agreed. After the panel ended, sisters Natalie and Andrea Crary, 25 and 23, approached Soares-Santos to find out more.
Natalie said the more we don't know, the more discoveries we have left to make. "It's true, we only understand so much," she said. "But it's going to stay put. And we get to shine our little flashlight around and figure it out."

NAME:
Joe Grange
WHICH UNIVERSITY DID YOU ATTEND?
University of Florida
WHO WAS YOUR ADVISOR?
Heather Ray
ON WHICH EXPERIMENT DID YOU WORK?
MiniBooNE
WHAT IS YOUR RESEARCH FOCUS?
I had lots of fun studying neutrino interactions with the MiniBooNE detector. I focused on optimizing the extraction of information from a neutrino-nucleus cross section.
HOW DID YOU GET INVOLVED IN PARTICLE PHYSICS?
The incredible opportunities to study the most fundamental constituents of our natural world and perhaps contribute to significantly advancing that knowledge were far too compelling to pass up.
WHERE DO YOU SEE YOURSELF IN FIVE OR 10 YEARS?
That's a great question — I admit I don't think about it as often as I perhaps should. For the moment, I'm still very much enjoying contributing to the fantastic culture of science at Fermilab.
DURING GRAD SCHOOL, WHAT WAS THE MOST UNUSUAL OR EXCITING THING YOU DID OUTSIDE OF PHYSICS?
After a conference in Asia, I took an opportunity to explore Nepal. While whitewater rafting with people from all over the world was certainly exciting, the exposure to a completely new and wonderful culture was invaluable for perspective.
WHAT ARE YOU GOING TO DO NOW?
As a postdoc at Argonne National Lab, I'm working on the realization of the crucial Muon g-2 experiment at Fermilab. It's an honor to be a part of a very small team charged with determining the magnetic field in the g-2 ring to a level of precision unprecedented for a magnet of its size.

Is the universe saddle shaped?
From Physics World, Sept. 19, 2013
The geometry of the universe is "open" or negatively curved like a saddle, according to a new model proposed by researchers in Europe who have studied anomalies in the cosmic microwave background radiation. The anomalies were first detected by NASA's Wilkinson Microwave Anisotropy Probe (WMAP) in 2004 and were confirmed earlier this year by the European Space Agency's Planck space mission.

Challenges, capabilities and collaboration

Mike Tartaglia

Michael Tartaglia, deputy head of the Magnet Systems Department in the Technical Division, wrote this column.
Two of the most interesting and exciting aspects of working in Fermilab's Technical Division are the large number and the diversity of advanced projects we have under development. These projects are intrinsically challenging from a technical-requirements standpoint, which reflects the ambitious demands of the Intensity and Energy Frontier machines. For each of many projects competing for our resources, there is also usually a challenge to deliver results on an aggressive schedule. Since other institutions around the United States and the world are engaged in various aspects of this work to develop new approaches and technologies, collaboration has become a very effective way to enhance the pace, spread the expertise and share the benefits.
A recent example illustrates how this has led to rapid progress in developing magnets to focus and steer beam within a superconducting radio-frequency cryomodule, the basic building block of a modern high-intensity linear accelerator. Motivated by discussions focused on building a proton driver and a proposed International Linear Collider, TD engineers designed superconducting magnets for such projects as early as 2005. The requirements for the ILC main-linac focusing magnets presented the greatest challenge; this design was the most interesting to develop, and it also is useful for other machines like ASTA and a future high-intensity proton accelerator at Fermilab. These cryomodules need a high-strength quadrupole magnet of short length, modest field uniformity and very stable magnetic axis over a wide range of operating strengths. An ultra-clean space within the SRF beam tube must be maintained.
Our KEK colleagues in Japan suggested splitting the Fermilab design into halves for clamping around the pre-cleaned beam tube. The coils are then cooled by thermal conduction to a cold pipe rather than immersing the magnet in a complicated liquid-helium vessel. In concert with Japanese industry, we prepared and assembled our magnet into a cryogenic test stand to assess the performance. Preliminary tests were made at KEK and then continued here, where versatile magnet protection and precise measurement systems were quickly configured to create a new test area.
Preliminary results indicate that this magnet meets ILC requirements! Now, two years after Fermilab tests began, we are about to learn how to install and operate a new magnet of this design in the first ILC-type cryomodule at KEK while we prepare for the next test in our new facility.

3-D vertically integrated chip
 |
| This 3-D vertically integrated photon imaging chip, better known as a VIPIC, comprises two interconnected layers of electronics. Designed by PPD's ASIC Development Group at Fermilab, which also organized its fabrication together with others in the HEP community, the roughly 6.5 mm-by-5.5 mm chip was assembled with a pixelated sensor, which is a source of charge signals arising from absorbed radiation. The group successfully met the challenge of mounting a sensor on an already multilayered chip, using solder bump bond technology and working with an industrial partner. By taking advantage of the 3-D design, engineers design chips that can process information from particle collisions or X-ray absorptions more efficiently than if the functionality were implemented in the larger footprint of a classical 2-D chip. The assembly below is ready for tests. Photo: Fermilab ASIC Group |

ESH&Q weekly report, Oct. 1
This week's safety report, compiled by the Fermilab ESH&Q section, contains two incidents.
An employee bent over to take a measurement when his hard hat fell forward off his head. Catching the hard hat and then standing up, he grazed his forehead against a piece of unistrut that protruded from the wall. He received first-aid treatment.
An employee struck her elbow twice on the surround around her desk, and the pain increased over time. The claim is pending.
Find the full report here.
