Faraday cage

A hollow metal cylinder used to detect ions in mass spectrometry. Ions enter the open end and impact either on the metal walls or the closed end. Each singly charged ion carries a charge of 1.6 x 1019 coulombs; the summed ion current carried by the ions is measured directly.

Faraday,

Michael, English physicist and chemist, 1791-1867.
farad - a practical unit of electrical capacity.

Then their charge polarity and charge density were measured with a Faraday cage. Hence, PP material that generates high charging efficiency with opposite polarity for PVC and XLPE was selected as the material for the charger.
This new AT&T Foundry is equipped with tools, including a 3D printer and a shielded copper testing room called a Faraday Cage that blocks external radio frequency signals, amongst others.
Along with the nickel-plated housing, this forms a conductive shell - or Faraday cage - around the electrical contacts to virtually eliminate electrical interference.
Static electric fields have the highest impedance and are completely controlled by a Faraday cage, which approximates a closed conductive shell.
The conditions at this level include; more complicated metal shapes (Faraday Cage)--still little non-metal substrates; more numerous color change demand (capital investment); smoother films are required (higher cost powder coatings and handling system); there is more stringent film thickness control; and toughness remains as powders core strength.
Then the Professor seriously examines the feasibility of erecting a Faraday Cage around every exam room in the country to render such technology inactive' although, of course, she is much exercised by the question of what human rights issues this measure would raise and she agonises over how a teacher, invigilating an exam, might summon assistance in the event of an emergency, without a mobile phone.
One possible way to stop cheating via mobile phones would be to put a "Faraday Cage" around every exam hall in the country to disrupt the connection, said the report's author, Professor Jean Underwood.
It is suited for use in any isolated environment and can be operated inside a Faraday cage. Radio frequency interference and electromagnetic field interference are non-existent.
Remember that the measured cell currents will be low, so a Faraday Cage should always be used.
Just as the sinuous copper cladding of the Signal Box 4 Auf dem Wolf in Basle also acts as a Faraday cage to protect the electronic equipment inside, so the skin of Dominus is both handsome and functional.
