Scientists at the U.S. Department of Energy\u2019s Argonne National Laboratory have developed a nanocryotron device to facilitate the operation of new particle colliders.<\/h2>\n

The new device acts like a superconductivity switch, boosting the signal of tiny particles in particle colliders.<\/p>\n

It does this by turning up a particle\u2019s electrical signal high enough to where it turns off the superconductivity of the material.<\/p>\n

\u201cThis work is especially important for collider experiments, such as those that will be performed at the Electron-Ion Collider<\/a> at Brookhaven National Laboratory,\u201d said Argonne Distinguished Fellow and group leader Zein-Eddine Meziani.<\/p>\n

A paper based on the study was published in Applied Physics Letters<\/a>. <\/em><\/p>\n

Why is the new device important?<\/h3>\n

Particle colliders reveal the hidden secrets of the tiniest constituents of our Universe.<\/p>\n

Miniature particles in these devices leave behind faint electrical traces when they are generated in enormous collisions.<\/p>\n

Some detectors use superconductivity to function. But to more accurately observe the behaviour of these particles, the electrical signals left behind need to be multiplied.<\/p>\n

To do this, an instrument capable of turning a faint electrical flicker into a jolt is required.<\/p>\n

Preparing the nanocryotron for a collider experiment<\/h3>\n

Preparing the nanocryotron for a particle collider experiment will take more work because of the high magnetic fields involved.<\/p>\n

Although today\u2019s particle detectors can withstand high magnetic fields, this switch\u2019s performance degrades when exposed to such high magnetism.<\/p>\n

\u201cFinding ways to make the device work in higher magnetic fields is key to incorporating it into a real experiment,\u201d said Argonne graduate research assistant Timothy Draher, one of the study’s authors.<\/p>\n

Modifying the device for use in particle colliders<\/h3>\n

To make the device work in higher magnetic fields, the researchers will change the geometry of the material and introduce defects.<\/p>\n

The defects will help researchers stabilise small superconducting vortices in the material. This movement can lead to an unanticipated disruption of superconductivity.<\/p>\n

The nanocryotron was created using electron beam lithography. This technique uses a beam of electrons to remove a polymer film to expose a region of interest.<\/p>\n

The region is then etched using plasma ion etching.<\/p>\n

\u201cWe basically just strip away the parts that are exposed, leaving behind the device that we want to use,\u201d Draher said.<\/p>\n

Work to perform reactive ion etching of the superconducting films in the experiment was carried out at the Centre for Nanoscale Materials, a DOE User Facility.<\/p>\n

The research was funded by DOE\u2019s Office of Nuclear Physics.<\/p>\n","protected":false},"excerpt":{"rendered":"
