electronvolt

(eV) A unit of energy representing the energy acquired by an electron in passing through a potential difference of 1 volt. 1 eV = (1.6 ± 0.000 07) x 10-19 J.

This is one of the reasons that Daniel Geelen, Johannes Jobst, Sense Jan van der Molen and Rudolf Tromp use slow electrons, carrying low energies of several electron volts (eV, hence 'eV-TEM') instead of the usual tens or hundreds of thousands of electron volts.
They rounded up data for gamma rays with energies above 31 million electron volts -- more than 10 million times greater than the energy of visible light -- and organized them over time, showing how longer exposures improve the view.
According to the observatory's readings, the gamma rays that hit Earth reached levels of over 100 trillion electron volts. To put this figure into perspective, the Large Hadron Collider located underneath the Swiss-French border smashes protons together at a maximum rate of 14 trillion electron volts.
HaloSat detects X-rays with energies between 400 and 2,000 electron volts, which enables it to find emission from ionized oxygen associated with superhot halo gas.
And the measurements were at the combined energy level of 7 trillion electron volts. At last, the multi-billion dollar scientific experiment to smash protons moving at near light-speed has been successful.
Most recently, it's slung subatomic particles into each other at ultra-high speeds and created energy measuring 13 trillion electron volts, breaking its own record of eight trillion electron volts.
These new chips offer an unprecedented level of acceleration, clocking in 300 million electron volts per meter.
Polytellurophenes have a band gap of about 1.4 electron volts, much lower than the 1.9 electron volts common for polythiophenes.
Volts" should be "one joule=6.241506363e+18 electron Volts."
Tuesday's experiment took place at a record total collision energy of 7 billion billion electron volts and at a nano-fraction of a second slower than the speed of light in the 16.8 mile Large Hadron Collider, about a hundred meters below the Swiss-French border.
In a milestone in the 10 billion USD Large Hadron Collider's ambitious bid to reveal details about theoretical particles and microforces, scientists at the CERN collided the beams and took measurements at a combined energy level of seven trillion electron volts. The collisions herald a new era for researchers working on the machine in a 17-mile (27 kilometer) tunnel below the Swiss-French border at Geneva, reported the AP on Wednesday.
