If they warm, magnets will quench-transition suddenly to a nonsuperconducting state-and suffer potentially permanent damage.Īn unambiguous indicator of an ample supply, says Kornbluth, was the lifting in March of rationing to the four refiners that draw from the federal helium reserve. Even with their laboratories shut down during the pandemic, scientists have had to periodically add helium to their magnets to keep them at or below liquid helium’s boiling point of 4.2 K. Unlike last year, when some scientists were forced to shut down their superconducting magnets for lack of helium (see Physics Today, April 2019, page 26), researchers now report they have no trouble getting the helium they need. The current supply situation, he says, is “between ample and plentiful.” It went from shortage to an ample supply within a month,” says Kornbluth. “It was like somebody flipped a light switch. Still, many scientists say the already historically high prices for the light element are continuing to rise.Īs demand for party balloons-which account for 10% or more of total helium use, according to market consultant Phil Kornbluth-disappeared in March, and as industrial demand slowed in concert with shelter-in-place orders, the global helium supply crunch of the past two years abruptly ended.
The coronavirus pandemic may have deflated uncounted birthday celebrations, but that’s been good news for physicists and chemists who need an assured supply of helium.

The cryomodules will house superconducting cavities that are cooled with liquid helium.
The future of your loved ones may depend on it.Cryomodules for the x-ray light source LCLS-II, to be located at SLAC in California, are under construction at Fermilab in Illinois. The helium crisis offers an opportunity for professionals from different sectors to come and work together for the common goal of healthcare sustainability.
Scientists and researchers at the University of California- Los Angeles have similarly initiated recycling efforts that have led to recovering over 90% of the helium that gets boiled off after use in a MRI magnet. For example, a collaborative team of physicians, scientists, and researchers at the University of California- San Francisco are finding innovative ways to recycle helium, leading to cost savings of at least $120,000 per year. In addition, finding creative ways to recycle helium have already been suggested and adopted by some institutions across the country. More efficient and judicious use of MRI will likely be needed in the future to ensure sustainability. Industry, tech, and medical professionals must work together to suggest feasible strategies to tackle this critical shortage. This then delays potential lifesaving treatment for your mother, leading to frustration and anxiety for your family. To your dismay, the Emergency Physicians tell you they cannot confirm your suspicion of a stroke diagnosis in your mother because the MRI (Magnetic Resonance Imaging) machine is non-operable. Immediately recognizing that these are the cardinal signs and symptoms of a stroke, you rush her to the Emergency Room to get diagnosed and treated. Imagine waking up one morning to learn that your mother is exhibiting slurred speech, difficulty understanding your words, and has weakness and numbness on one side of her body.
