In Brief

Scientists celebrate 20th anniversary of top quark discovery at Fermilab

The Top at Twenty workshop takes place from April 9-10 at Fermilab.

Twenty years ago today, scientists on the CDF and DZero experiments announced the discovery of a new particle — the top quark. With this monumental 1995 milestone, scientists confirmed the existence of the final member of the Standard Model's quark sextet.

From April 9-10, the particle physics community will commemorate the event with a workshop titled Top at Twenty, to be held at Fermilab.

The top quark is the heaviest subatomic particle ever observed, and the study of this particle continues to be a vibrant area of particle physics research.

Speakers from CDF and DZero at the Tevatron and ATLAS and CMS at the Large Hadron Collider will present recent results of their top quark studies at the workshop. They will also examine how top quark production and decay illuminate the nature of the Higgs boson; review measurements of the top quark; and discuss how the quark fits into the Standard Model and its potential extensions.

Registration is free. To register and for more information, visit the workshop website.

Explore the Wonders of Science at Fermilab on Sunday, March 15

If you know kids between the ages of 7 and 12, you know how hard it can be to get them excited about science from a textbook. Children need science to come to life before their eyes. They need to be wowed and to experience physical phenomena with eyes wide and jaws dropped.

That's the thinking behind the annual Wonders of Science show, which will again pack Ramsey Auditorium at the U.S. Department of Energy's Fermi National Accelerator Laboratory on Sunday, March 15, at noon. The show, organized and performed by award-winning high school teachers, is celebrating its 28th year at the lab. Tickets are $4.50 per person.

"This is one of our most exciting events every year," said Spencer Pasero, an education program leader at Fermilab. "Everyone has their favorite demonstration, but there's always something new and exciting to look forward to."

Scientists may have solved mystery of matter's origin

From The Washington Post, Feb. 26, 2015

For decades, scientists have puzzled over one of the central, most essential mysteries of physics: Where did all the stuff that makes up the universe come from?

Now researchers at the University of California at Los Angeles think they have an explanation, which they describe in the journal Physical Review Letters this month. Based on observations of the Higgs boson field at Switzerland's Large Hadron Collider, the paper is fairly impenetrable for the lay reader — even the abstract contains few words with less than four syllables.

Tip of the Week: Safety

Extension cord and power strip safety

Extension cords and power strips offer convenience and flexibility, but improper use can create fire hazards and is the most commonly cited problem during safety inspections at Fermilab.

The most frequent violations are:

1. High-power appliances plugged into power strips: According to the rules of safety standards company UL and Department of Energy policy, high-power devices such as space heaters, refrigerators and most counter top kitchen appliances must be connected only to permanent building outlets, not to extension cords or power strips. Heavy-duty extension cords, called appliance cords, may be used for these appliances if a work area cannot be rearranged to eliminate the need. They are available from the Fermilab stockroom, item numbers 1170-092000 and 1170-094000.

2. Daisy chains: A daisy chain is a power strip or extension cord that is plugged into another power strip or cord. Daisy-chaining is not allowed at the laboratory. Each power strip and extension cord must be plugged into a permanent outlet. The stockroom carries a power strip with a 25-foot cord (1170-102300) to help prevent this problem.

3. Improper installations: Extension cords and power strips are considered temporary wiring, so they must be accessible and removable. Cords cannot be attached to or hidden in walls, ceilings or under carpet and flooring. Access to their plugs cannot be blocked by heavy furniture or equipment. To prevent pinching and fraying, cords must not pass through windows or doorways. To protect cords and reduce tripping hazards, cords that cross passageways must have covers. See stockroom number 1125-120000. Power strips cannot hang from their cord or the cords of their loads. The receptacle end of a power strip may be attached to a building or furniture, but it must be removable without tools.

4. Overloads: An appliance's power draw (in watts) is found in the fine print on its bottom or side. The total watts of all loads on cord or power strip must not exceed its capacity. A power strip's capacity is found in its fine print; the capacity of a cord is determined by the size of its wires. A cord's wire size, for example 18 AWG, is stamped into its jacket. The capacity of an 18 AWG cord is 960 watts; for 16, 14, and 12 AWG cords, the watt limits are 1,248, 1,728 and 2,400 respectively.

5. Wear and damage: Cords and power strips that have been damaged or that no longer hold plugs firmly in their receptacles are a fire hazard that must be promptly replaced or repaired by trained personnel.

For more information, please see the Electrical Safety Subcommittee's determinations regarding multiple outlet strips and appliance cords and the Visual Guide to Stockroom Electrical Safety Supplies.
