Positrons from Geminga Now, Hasan Yuksel and Todor Stanev at the University of Delaware and Matthew Kistler at Ohio State University claim that the source of these positrons is Geminga — a nearby and ...

One possibility is that the positrons come from nearby pulsar wind nebulae, which are fast-spinning neutron stars that act as cosmic ray accelerators and produce streams of electrons and positrons.

Experiments reveal that positrons — the antimatter equivalents of electrons — can be rapidly accelerated using a plasma wave. The findings pave the way to high-energy electron–positron ...

These positrons could be trapped in an electromagnetic voltage trap with about 30 percent efficiency, with the resulting antimatter plasma lasting about one minute.

“It’s no longer simply perturbing the ocean, it’s completely remaking it.” This non-linear plasma environment offers high acceleration gradients and focusing for electrons, but the effect on positrons ...

The positrons were registered by counting the coincidences they produce in two Geiger-Müller counters1. The source from which the positron emission was observed was an aluminium strip 10 thick ...

Under the right conditions, positrons and electrons can pair up and orbit one another without touching or annihilating themselves. This paired arrangement, which behaves like a hydrogen atom with ...

The power of positrons Medical imaging: Positron-emission tomography is more expensive and complex than other body-scanning technologies. But, as this case history explains, it has proven its ...

Positrons are the antiparticles of electrons, they have the same properties except that they are positively instead of negatively charged. When a positron hits an electron, both instantly ...

Spinning electrons yield positrons for research Date: June 1, 2016 Source: DOE/Thomas Jefferson National Accelerator Facility Summary: A team of researchers has successfully demonstrated a new ...

Extra positrons make for a cosmological mystery More results are released in this week's issue of Nature that find too many … Matt Ford – Apr 1, 2009 9:00 AM | 15 ...

To measure the abundance of positrons in cosmic rays, the team used data from the instrument PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics), which launched aboard ...
