Again, Tevatron Sets World Record for Peak Luminosity
On Tuesday, October 25, at 3:28 a.m. the Tevatron improved its world-record peak luminosity to 144.91E30 cm-2sec-1. Significant contributions came from the new electron cooling system, which will be featured in an upcoming luminosity series in Fermilab Today. Congratulations!

Computer Security: Watch Out For Con Artists' Games
In computer security, social engineering describes a non-technical kind of intrusion that often involves tricking other people to break normal security procedures. In short, social engineering is a con game. Consider the following true examples:

Jane enters a government facility by simply talking to employees and 'piggybacking' through the doors. Guards ignore her since she is with a group of employees, some of whom swipe their cards to unlock the door. Once inside, she breaks off from the group and finds her way to the server room. She finds an administrator along the way and convinces him that she works for a vendor, was installing some software and accidentally locked herself out of the server room. He dutifully lets her in the server room without further question. She is left alone with the core servers, well on the way to gaining unauthorized access.

Hundreds Gather to Honor Top Quark Discovery
TTT Celebration
The Wilson Hall Atrium was filled with revelers at the Top Turns Ten Celebration last Friday.
The Wilson Hall Atrium buzzed on Friday as hundreds of Fermilab scientists, employees and visitors gathered to celebrate the 10th anniversary of the top quark discovery. Inside the Atrium, people inspected an array of posters highlighting the discovery's technical aspects, its meaning and the parties that ensued. And in the Ramsey Auditorium, scientists who witnessed the challenges and triumphs of finding the top shared their memories with the audience.

CDF's Doug Glenzinski, a graduate student at the time of the discovery, offered a perspective a young physicist caught up in the excitement. He described fierce internal competition, a lack of sleep and sitting through 5-hour-long meetings in crammed Wilson Hall rooms. "There were no laptops then, so everyone was paying attention," he said wryly. He also reminisced about student camaraderie and lessons learned along the way. "We learned a great deal," he said. "This was our introduction to the Scientific Method." Meenakshi Narain, a DZero postdoc during the discovery, talked about intense debates questioning whether or not to publish early top findings. She said she'll always remember a congratulatory note circulated by the experiment's spokesmen after the discovery: "You don't get to be part of a team that discovers a new elementary particle more than once."

But maybe you can. "This opens up a very broad range of physics," Fermilab Director Pier Oddone said during his closing remarks. "We are no longer just looking for a single thing." With the high energy of CERN's Large Hadron Collider and an increase in luminosity at the Tevatron, Oddone said other discoveries wait ahead. "It's clear we're headed to an area where we all expect a revolution," he said. "The thing that would top the top would be to find something unexpected."

In the News
High Energy Accelerator Research Organization (KEK)Press Release, October 24, 2005:
Request for Candidate Recommendations for the Position of the Next Director General

KEK, the High Energy Accelerator Research Organization, welcomes recommendation of the candidates for the next Director-General whose term will begin April 2006.

KEK is an Inter-University Research Institute Corporation open to domestic and international researchers, and is comprised of the Institute of Particle and Nuclear Studies, the Institute of Materials Structure Science, the Accelerator Laboratory, and the Applied Research Laboratory. KEK pursues a wide range of research activities based on accelerators, such as particle and nuclear physics, material sciences, biosciences, accelerator physics and engineering, etc.

The role of Director-General, therefore, is to promote, with long-term vision and strong scientific leadership, the highly advanced, internationalized, and inter-disciplinary research activities of KEK by getting support from the public. He/she is also expected to carry out the medium-term goals and plans of the organization.

Director's Corner
Top Fun
Friday's celebration of the tenth anniversary
Pier Oddone
Pier Oddone
of the discovery of the top quark by DZero and CDF was a rare treat. It is not often that we hear erudite talks about accelerators and physics alongside talks about the high emotions and the drama behind great discoveries. The search for the top quark was a world-wide saga lasting more than two decades. Many fell by the wayside, as accelerators "sure" to create top quarks fell short of the energy required to produce them. At some point, as the limits on the mass of the top quark rose to higher and higher levels, only the Tevatron remained.

The story of the Tevatron is as rich as the machine is complex and goes back to nearly the beginnings of the laboratory. The real fun of the top discovery started when the accelerator produced a significant rate of collisions. The two collaborations raced to the discovery at a time when they were still trying to understand their detectors. The protagonists told stories about how the excitement of making a great discovery was balanced by the terror of getting the wrong result. They explained with humor and candor the dynamics of the two collaborations and how they affected the way the early results were treated. For those of us who were not there, it was a very special glimpse into the inner workings of these two complex and ultra -competitive enterprises.

Will we have a celebration for another great discovery? We are at a threshold moment when the improvements of the Tevatron to achieve much higher luminosity coupled with the increasingly powerful analysis of data give us a great window for discovery. The race will be even more interesting than for the top quark as the two collaborations race not along one front, but along multiple fronts. If the top celebration was fun, think about how much fun the next one will be.

Congratulations to Peter Limon and Judy Jackson! Peter Limon, a Fermilab physicist in the Technical Division and Judy Jackson, the head of Fermilab Public Affairs, were married on Saturday, October 22. The wedding was at 4:00 p.m. at their home in Naperville with their children in attendance. (Click on image for larger version.)
