| DRAFT DEFINITION |
| Nier-Johnson geometry |
|---|
| An arrangement for a double-focusing mass spectrometer in which a deflection of ????????????????/2 radians in a radial electrostatic field analyzer is followed by a magnetic deflection of ????????????????/3 radians. |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |

Orange Book Entry
An arrangement for a double-focusing mass spectrometer in which a deflection of ????????????????/2 radians in a radial electrostatic field analyser is followed by a magnetic deflection of ????????????????/3 radians. The electrostatic analyser uses a symmetrical object-image arrangement and the magnetic analyser is used asymmetrically.
