Ionic crystal generates molecular ions upon positron irradiation

The positron, the antiparticle of the electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of positrons has led ...

Direct observation of the electron and positron capture process

Positrons are anti-particles of electrons. At SuperKEKB B-Factory (SuperKEKB), they are produced in copious amounts and smashed into electrons at world-record luminosity. By studying the hundreds of decay patterns of B mesons ...

Positron luminescence outshines that of electrons

In old cathode ray TVs, a picture is generated when an electron beam excites a phosphor screen, causing the phosphor to radiate light. Now in a new study, researchers have found that a beam of positrons (positively charged ...

Spinning electrons yield positrons for research

Researchers use accelerators to coax the electron into performing a wide range of tricks to enable medical tests and treatments, improve product manufacturing, and power breakthrough scientific research. Now, they're learning ...

BEPCII luminosity sets world record as 1*10^33/cm^2/s

At 22:29 pm, April 5th, the luminosity of the Beijing Electron Positron Collider (BEPCII) reached 1×1033cm-2s-1, a new landmark in the performance of the BEPCII— 100 times better than before it was upgraded. This is also ...

A Flight Simulator for the World's Smallest Beam

(PhysOrg.com) -- Commissioning has begun at the Japan-based Accelerator Test Facility 2, a major technology test bed for future accelerators, including the proposed International Linear Collider, or ILC. During the two-year ...
