Sentences with phrase «trapped by magnetic fields»

Not exact matches

They monitored how superconducting balls respond to gravity while trapped floating in ultrastable magnetic fields generated by superconducting coils.

Li's team showed that during CRAND, cosmic rays entering Earth's atmosphere collide with neutral atoms, creating a splash that produces charged particles, including electrons, that become trapped by Earth's magnetic field.

The greenish glow in the center of Io's disk is thought to be caused by high - speed particles that batter the moon's atmospheric oxygen or sodium gas — the particles are trapped in Jupiter's powerful magnetic field.

In breaking this record, Eric Cornell and his colleagues in Boulder cooled rubidium atoms to 5 microkelvin by optical molasses, and then turned off the lasers while keeping the atoms trapped in a magnetic field.

NASA might choose to extend it, but the spacecraft could still succumb any day to the intense radiation from the deadly halos of high - energy particles trapped around the planet by magnetic fields.

The core of the device uses cusp confinement, a sort of magnetic trap in which particles that try to escape are pushed back by rounded, pillowlike magnetic fields.

It detected the first traces of the belts of protons and electrons, trapped by Earth's magnetic field, that bear Van Allen's name.

Scientists on that mission claimed to find protons — perhaps a small radiation belt trapped by Mercury's magnetic field.

Instead of permanently depositing particles through immunoaffinity, anti-EpCAM coated magnetic microparticles were trapped over the untreated PDMS surface by an external magnetic field and were then released by readily removing the magnet for CTC collection.

These defects «pin» in place, or trap, the microscopic magnetic vortices that form when the superconductor is placed in a strong magnetic field, such as those generated by magnets in magnetic resonance imaging (MRI) machines.

Atoms are slowed and cooled by radiation pressure from laser light and then trapped in a bottle whose walls are magnetic fields.

Paul realized that it is possible to design a magnetic field with a local minimum in the field strength, and if the magnetic dipole is originally aligned to seek a position where the field is weakest, it will remain aligned in the «weak field - seeking» orientation [see «Cooling and Trapping Atoms,» by W. D. Phillips and H.].

External magnetic fields exert forces on them, levitate them against gravity and keep them together; the atoms are trapped in a magnetic cage with invisible walls formed by magnetic fields.

The belt, which consists of antiprotons trapped by Earth's magnetic field several hundred kilometers above the planet's surface, may ultimately become a key source of fuel for missions venturing beyond the solar system.

High above Earth, two giant rings of energetic particles trapped by the planet's magnetic field create a dynamic and harsh environment that holds many mysteries — and can affect spacecraft traveling around Earth.

Earth's magnetic field also traps gas escaping from the upper atmosphere after it gets ionised by ultraviolet light from the sun.

The quantum Zeno effect was first observed experimentally in 1989 in laser - cooled ions trapped by magnetic and electric fields.

The team suggests the unexpectedly large quantity of methanol may have two possible origins: either a cloud of gas expelled from Enceladus has been trapped by Saturn's magnetic field, or gas has spread further out into Saturn's E-ring.

Radio astronomers discovered intense belts of radiation surrounding Jupiter created by electrons trapped in its powerful magnetic field — 10x the Earth's!
