Superconducting devices measure fetal heartbeats and more

By Jeffery Kahn, [email protected]

Scientists have developed a new generation of superconducting electronic devices able to measure extremely faint magnetic fields. Practical and affordable, these "magnetometers" make possible a broad range of new medical instruments and industrial tools.

Materials Sciences Division physicist John Clarke, who led the collaborative effort, says fetal cardiology is likely to be the first commercial usage. The stage was set in 1991 when the collaborators developed the first magnetocardiogram with a high-temperature thin-film magnetometer. The device detects faint magnetic signals produced by the beating of the human heart, creating a waveform which a doctor can examine much like an electrocardiogram.

"Measuring the cardiogram of an unborn child's heart can provide invaluable information," Clarke says. "But after about 22 weeks, it is generally impossible with existing electrical techniques. With the improvements in magnetic field sensitivity we've made, we can now do this with a high Tc magnetometer. You can now imagine having these instruments in a doctor's office."

Superconducting magnetometers have existed for decades but until the recent advent of high transition temperature (high Tc) superconductors that can operate in liquid nitrogen, they relied on low Tc helium-cooled superconductors. These sensors have a variety of applications but their use has been restricted because of the cumbersome and costly nature of helium cooling.

Clarke explains: "The central problem in creating usable high Tc superconducting magnetometers has been that these materials produce considerable `noise.' Through multiple breakthroughs in material science, we have managed to beat the noise power down to one part in ten-million of the level five years ago."

People with heart arrhythmias also should benefit. In Germany and Nova Scotia, for example, studies are under way using arrays of helium-cooled magnetometers to image pathways in the heart magnetically. These arrays paint a picture showing the location within the heart where the electrical short-circuiting responsible for the arrhythmia is occurring. This procedure helps doctors zero in and selectively treat the defective area using catheter ablation.

While extremely promising, this approach is handicapped by the use of helium-cooled materials. The high performance, high Tc magnetometers should help transform this experimental medical program into a more affordable and widely available procedure.

Geophysics and the search for underground natural resources also should be major beneficiaries. Collaborating with Conductus, a private firm based in Sunnyvale, Clarke's team recently field-tested a sensor that provides a three-dimensional measurement of time-varying magnetic fields. The device makes possible a family of instruments useful in oil exploration, geological surveying, and environmental investigative work.

Magnetometers actually consist of two coupled devices, a superconducting quantum interference device (SQUID) and a flux transformer. The flux transformer serves as an amplifier, picking up weak magnetic signals over a large area and inducing a proportional magnetic flux in the tiny hole of the SQUID. The SQUID, which consists of a loop of superconducting film interrupted by two weak links or "Josephson junctions," responds to the magnetic field by producing a corresponding voltage signal.

The magnetometers were developed by a team led by Clarke that includes researchers at LBL, UC Berkeley, and Conductus Inc. The collaboration includes Berkeley postdocs Dieter Koelle and Frank Ludwig; Berkeley graduate students Gene Dantsker, Andy Miklich, and David Nemeth; and Conductus scientists Kookrin Char and Ward Ruby. A Cooperative Research and Development Agreement between LBL and Conductus helped fund the transfer of the technology to industry.

Galvin Task Force tours LBL

Members of the Galvin Task Force on Alternative Futures for the DOE National Laboratories toured LBL on Wednesday, June 15. Formed by Energy Secretary Hazel O'Leary in February, the group of leaders from industry and academia is spending 1994 charting the future of DOE's nine multi-purpose national labs.

The group's final report, expected in early 1995, will focus on ways to develop the national labs, in particular to strengthen ties with the private sector. According to O'Leary, the report's recommendations could involve the redirection, conversion and closure of elements within the DOE laboratory system.

During its afternoon visit, the task force toured the National Center for Electron Microscopy, the Life Sciences facilities at Bldg. 74, and the Advanced Light Source. The group also met with LBL management, which included Lab Director Charles Shank, Deputy Director Pier Oddone, Associate Lab Director of Operations Klaus Berkner and Associate Lab Director of Administration Rod Fleischman. The task force visited Lawrence Livermore National Laboratory Wednesday morning.

Members of the task force visiting LBL included Robert Galvin of the Motorola Corp., who heads the group, Linda Capuano of Conductus Inc., Mark Murphy of Strata Production Co. and Ben Rosen of Compaq Corp. Michelle Donovan, Staff Director for the task force, also participated.

Lab to start leasing most of its vehicles

In a move that should result in newer vehicles and reduced monthly mileage charges for Motor Pool customers, the Lab is transferring management of most of its DOE vehicles to the General Services Administration (GSA). The move is also projected to save the Lab some $140,000 per year.

The first phase of the transition began last week, when 161 DOE-owned vehicles received new GSA license plates. The move followed months of planning and negotiation with GSA. LBL already leases 89 vehicles from GSA.

"Our fleet was the oldest in the DOE family," says Motor Pool supervisor Fred Schirmer. "With capital equipment money becoming scarce at the Lab, we started looking at leasing as a way of improving the fleet." A cost analysis study commissioned by Rod Fleischman, Associate Lab Director for Administration, determined that allowing GSA to manage the LBL fleet would save the Lab money, and nearly eliminate capital equipment costs for replacement vehicles.

"GSA has agreed to bring our fleet up to date within five years--and may do it much faster as vehicles are transferred from military bases that are being closed down," Schirmer says. "The GSA's standard is to replace sedans every three years or 30,000 miles, pickups every six years or 50,000 miles, and large trucks every eight years or 70,000 miles." A new fleet will mean increased reliability and decreased repair costs for departments that use Laboratory vehicles, as well as decreased fuel consumption and pollution.

Another advantage of using GSA, according to Schirmer, is the increased flexibility in managing vehicles. Since the vehicles will be leased rather than owned, the fleet can be quickly modified to meet changing needs at the Lab. "For example, users will be able to get rid of vehicles they no longer need, or switch from a van to a pickup without costing the Lab money in terms of capital equipment losses."

Schirmer says the Motor Pool will still be the coordinating group for all vehicle activities. "We'll still take care of maintenance, repair, and replacement for all of the GSA vehicles."

Stack parking a choice for some commuters

To lessen the parking pinch at LBL, Lab managment has designated several "stack" parking areas around the Hill. Stack parking involves parking one car behind another, blocking one or more cars in front. This plan works well for employees who do not usually move their cars during the day.

If you plan to use stack parking, please remember to observe the following regulations; otherwise, you may be subject to citation:

Stack parking cards are available from the Reception Center at X6155, or via cc-mail or Mac Quickmail.

LBL PEOPLE:

Tony Hansen, a physicist with LBL's Human Genome Center, attended the May 12-13 meeting of the Gore-Chernomyrdin Science and Technology Committee, which met in Washington, D.C., to discuss ways to streamline U.S.-Russian cooperative efforts. At the meeting, Hansen presented an example of a successful U.S.-Russian collaboration. Two years ago he and other American scientists teamed up with the Russians to solve the mystery of the Arctic plumes, an unusual cloud formation thought at one time to be methane gas bubbling up through the ocean. The project "illustrated that cooperation is possible, that it can be vital and rewarding and yield good scientific results," Hansen said.
