ATLAS is now accelerating ions for a broad range of physics experiments 24 hours a day, seven days a week, stopping only for holidays.
"It's a big increase in time-on-target," said ATLAS Operations Manager Richard Pardo. "And seven-day operation is much more efficient than starting and stopping once a week." It takes most of a day to restart the complex machine, a string of magnets and accelerator segments winding almost 500 feet (150 meters) through a maze of large rooms in Building 203.
ATLAS is the world's first heavy-ion accelerator to use superconducting elements for beam focusing and acceleration. Superconducting resonators in ATLAS make possible a continuous beam. Traditional materials would produce too much heat, requiring a pulsed beam.
ATLAS provides nuclear scientists with beams of ions (atoms minus one or more electrons) as heavy as uranium-238 to energies as high as 1.5 billion electron volts. Physicists use the machine to probe the structure of atomic nuclei under extreme conditions by studying the gamma rays and particles emitted when ATLAS beams smash into targets.
A user facility, ATLAS hosted 161 scientists from 22 American universities, five national laboratories and 16 foreign institutions in 1994. Twice as much time on the machine has been requested as is available.
Her four-year term begins in February.
Founded in 1848, AAAS has more than 138,000 members, whose interests lie in all aspects of science, including technology, engineering, education, and policy-making. AAAS is the world's largest federation of scientific and engineering societies, with 287 member organizations cooperating with the society on a variety of projects.
Dehmer has previously served on the Advisory Committee for Physics of the National Science Foundation and on the Council of the Gordon Research Conferences. She has also held a number of elected positions in the American Physical Society (APS).
"I find myself sleeping a lot more than last year," said Grounds Foreman Robert LeClercq (PFS), one of the crew who clears snow from Argonne's streets and sidewalks between 2 a.m. and 7 a.m.
"It has been a light year so far," said Richard A. Pagel, manager of PFS site services. "Before the first of January we hardly had any snow."
Of course, winter isn't over yet. Last year, the PFS division was stretched to the limit as 26 inches of snow fell in February. Argonne, along with the whole Chicago area, nearly ran out of road salt. Pagel said 300 to 400 tons of salt will be needed in a typical year but 2,000 tons were used last year. The price of salt jumped from $30 per ton to $98 per ton as shortages hit. Overall, 1994's severe weather caused Pagel to go $250,000 over budget.
He expects no such problems this year, however. The laboratory has a new dome that can store 1,500 tons of salt, more than twice the old dome's 600-ton capacity.
A crew of 10 grounds specialists and two heavy equipment operators take care of snow removal at Argonne. When a snowstorm hits, Pagel said, the first priority is to keep roads clear. "As people leave, we have one salt truck that keeps the roads passable. We can't do much about parking lots until they clear out," he said. The crew comes in to finish the job at midnight, 2 a.m. or 4 a.m., depending on the amount of snow. They have to clear most of the 36 miles of roads, 45 acres of parking lots and 4.4 miles of sidewalks before 7 a.m. when employees begin to arrive.
Pagel said Argonne uses regular snowplows on the main streets, a 20-foot-wide plow for parking lots, and riding lawn mowers equipped with plows to clear and salt sidewalks. Crews do some hand shoveling and cleaning around handicapped parking spots.
Overall, Pagel says the laboratory is in good shape for the rest of the winter. "So far this winter has been better than normal," he said. "But we are ready for whatever comes. We got a lot of practice last year."
The program's specially-trained counselors will provide help with nutrition, physical exercise, behavior modification and stress management. The four-week program, conducted by Hinsdale Hospital, claims a 90 percent success rate for those who attend all sessions.
An orientation session will be held Wednesday, Jan. 18. Clinic sessions will be held Jan. 23, 25 and 30, and Feb. 1, 6 and 8. All sessions will be held from 8 a.m. to 9 a.m. in the Building 213 cafeteria, conference room B.
The $45 cost will be refunded if the participant remains a non-smoker for six months. For more information, call ext. 2-2813.
Sponsored by the Argonne Chapter of Sigma Xi, the national honor society, Ziemer's talk will begin at noon in the Building 203 auditorium. He will discuss new studies on radon gas, a major contributor to the natural radiation exposure of the average person.
The talk is open to all Argonne employees. Offsite visitors should contact Tony Zeuli (PHY) at (708) 252-5364 to arrange for site access.
A "beach party" will be held in the Building 213 cafeteria Thursday, Jan. 19, from 4:30 to 8 p.m. The party will include music, food and dancing, and a Marriott weekend package will be awarded for the "most creative beach attire."
The pneumatics course provides three hours of college credit in manufacturing technology. Topics include advanced principles of fluids at rest and in motion, fluid system cycling and design of circuitry, pumps, motors, intensifiers, valves, accumulators and piping.
Class will meet on-site for ten weeks on Wednesday afternoons from 4:30 p.m. to 7:15 p.m. For more information, call Karen Kroczek at ext. 2-8764 as soon as possible.
The exam will be offered Feb. 9, from 9:30 to 11 a.m. in Building 202, room E126, rather than Feb. 2 as shown on the printed schedule.
