Spell out in first use then use acronym for the CERN Courier

no hyphen, no space, not "straight-section" or "straightsection"

Straps are a maximum of 150 characters, including spaces. 

The strap gives added “teaser” information not included in the headline, providing a succinct summary of the most important points of the article. It tells the reader what to expect, and invites them to find out more. 

Remember the strap will always appear with the headline, never on its own, and usually in lists.

Such a list might appear on the site like this (headlines in bold, straps below): 

use hyphen

A neutrino detector in Japan. 

Capital S, capital K, hyphen. 

See their website. 

​Spell out in full for the CERN Courier

Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature. 

Superconducting is preferable to "superconductive" as an adjective (though both are technically correct). 

The superconducting wires on the Large Hadron Collider are maintained at 1.9 K (-271.3 °C) – colder than outer space – by a closed liquid-helium circuit.

Supersymmetry

Capital "S" when referring to CERN's first particle accelerator. Otherwise, lower case. 

A synchrocyclotron is a type of cyclotron in which the frequency of the driving radiofrequency-electric-field is varied to compensate for relativistic effects as particle velocity approaches the speed of light. This is in contrast to the classical cyclotron, where this frequency is constant.

Not "synchro-cyclotron" or other such historical derivations.

A synchrotron is a cyclotron in which the magnetic field strength increases with the energy of the particles to keep their orbital radius constant.
