A bouquet of options: Higgs factory ideas bloom

Now that a Higgs-like boson has been discovered at the Large Hadron Collider, proposals to build colliders that churn out the new particle are gathering momentum. Image: Sandbox Studio

If you hurl two oranges together at close to the speed of light, there's going to be a lot of pulp. But, somewhere in the gooey mess will be the rare splinters left over from two seeds colliding.
The Large Hadron Collider at CERN works in a similar way. Protons, each made of quarks and gluons, collide and produce other particles. Roughly once every 5 billion proton collisions, everything aligns and a Higgs-like boson pops out.
It's a messy and inexact process. But that messiness gives scientists a way to observe a broad range of physics. Because all that pulp and the occasional seed collide in a different way almost every time, a huge array of particles can appear.
"It's a broadband machine," says Lyn Evans, the former director of the LHC. "Wherever the Higgs is, it will pop out, out of the noise."
Now that a boson with Higgs-like qualities has been found, physicists are calling for something more precise: a Higgs factory that would collide elementary particles to produce Higgs bosons in droves without all the distracting pulp. By colliding particles that don't break down into composite parts as they produce Higgs-like particles, a Higgs factory could allow a more precise view of the new boson.

Particle physics research: impact and applications
From ISTC Catalyst, November 2012
Editor's note: Bob Kephart, Director of the Illinois Accelerator Research Center, wrote this article.
More than 30,000 particle accelerators are in operation worldwide. Unseen by most of us they quietly implant ions in the microchips of cell phones and computers, destroy cancer tumors, create medical isotopes, fabricate car and airplane components, develop new drugs, and discover the secrets of the universe.
Fermi National Accelerator Laboratory is America's premier national laboratory for the development, construction and operation of particle accelerators. Our seven particle accelerators—the largest of which is two miles around—drive scientists' exploration of the nature of matter, energy, space and time.

100-gigabit Ethernet technology coming to Fermilab
 |
|
Jon Bakken

Jon Bakken, head of the Core Computing Division, wrote this column.
Upgrades are coming to Fermilab's network capabilities. The upgrades will substantially increase the laboratory's off-site bandwidth capacity. Perhaps just as significantly, the upgrades will keep the laboratory's wide-area network infrastructure on the leading edge of network technology. To put things into perspective, after the upgrade our bandwidth will allow us to stream about 25,000 HD Netflix movies simultaneously—but we of course don't do that. We have better things planned.
Today, off-site network connectivity is provided through a metropolitan-area network (MAN) called ChiMAN. ChiMAN is an optical network infrastructure based on 10-gigabit Ethernet (10GE) technology and has been in place at the laboratory since 2006. ChiMAN currently provides eight 10GE channels to the laboratory for an aggregate of 80 gigabit-per-second off-site capacity. Two of these 10GE channels are dedicated for general user traffic such as the use of Web, e-mail and collaborative tools. Five 10GE channels are allocated for high-impact scientific data movement such as LHC CMS data. The remaining 10GE channel is used for network-related R&D activities.
ESnet, the laboratory's Internet service provider, is in the process of rolling out its latest network, ESnet5. ESnet5 is based on an advanced network infrastructure that includes 100-gigabit Ethernet (100GE) technology. Part of ESnet5 will be a new Chicago-area MAN, called ChiExpress, which will replace ChiMAN. The initial configuration of ChiExpress will provide the laboratory with one 100GE channel and three 10GE channels for an aggregate of 130 gigabit-per-second off-site capacity. The 100GE channel will be allocated primarily for moving high-impact scientific data, which makes up 95 percent of the laboratory's off-site network traffic. The excess capacity on that channel will be made available for various network, middleware and application R&D activities. The ChiExpress 10GE channels will be dedicated to general user traffic, in a fashion similar to ChiMAN today.
The initial 100GE deployment at Fermilab will be a router to support the ChiExpress 100GE channel. Internal production network 100GE infrastructure should follow in the coming years as the technology becomes available on a wider and less expensive spectrum of network platforms.

Obituary: Robert E. Shafer June 2, 1936–Nov. 11, 2012
From the Los Alamos Daily Post, Nov. 11, 2012
Editor's note: Robert Shafer, a world-class expert in beam instrumentation for particle accelerators, worked at Fermilab from 1969-1986. He is largely responsible for the Chipmunk and Scarecrow radiation monitoring devices widely used in Fermilab radiation protection systems. He also led the system design efforts for the Tevatron beam loss and position monitors and contributed to beam instrumentation developments at many other accelerator facilities.
Robert E. Shafer died suddenly at his home Sunday, Nov. 11, 2012. Born in Berkeley, Calif., June 2, 1936, he was 76 years old.
He is survived by his wife Ann Shafer, his sister Gretchen Simpkins, and his beloved Scottish terrier Rosie. He was preceded in death by his brother Paul and by his parents Margaret Shafer and Eugene Shafer.
Robert Shafer was a recognized expert in beam instrumentation for charged-particle accelerators. He is best known for his world-class expertise on Beam Position Monitors.
