CERN Scientific Team Develops Transportable 'Antimatter Trap'

Antimatter is matter defined in modern physics as being composed of antiparticles of the corresponding particles of “normal” matter. CERN’s BASE team conducts the research, and is behind several antimatter breakthroughs.

A BASE collaboration at CERN (European Organization for Nuclear Research) revealed that it is developing a “transportable antiproton trap”, which will allow the transportation of antiprotons from CERN’s Antimatter Decelerator (AD) to other laboratories to continue examination.

Currently, antiprotons are stored in a device called a Penning Trap, which holds particles in place with a combination of electric and magnetic fields. Those entrapped particles are then fed into a multi-Penning-Trap set-up to measure two frequencies – a cyclotron frequency, which describes a charged particle’s oscillation in a magnetic field, and a Larmor frequency, which describes the so-called precessional motion in the trap of the intrinsic spin of the particle.

As the AD remains the only place in the world where antiprotons are produced daily, the properties can be measured more precisely in a magnetic environment that is calmer than that of the AD. Looking for more precise measurements, the BASE team came up with an antiproton trap – a device named BASE-STEP, which will allow the transportation of antiprotons to places with suitable magnetic environment.

BASE-STEP will consist of a Penning Trap inside the bore of a superconducting magnet capable of withstanding transport-related forces. It will also have a liquid-helium cooling system which will allow it to be transported for several hours without needing electrical power to keep it cool.

The device is anticipated to be 1.9 metres long, 0.8 metres wide, 1.6 metres high and, at most, 1000 kg in weight.

Currently, with its first components under development, the BASE-STEP is expected to be completed in 2022.
