| {{DefName|
| |
| A conversion [[dynode]] is used to increase the secondary emission characteristics for heavy ions and thus reduce the mass discrimination of the detector. A high potential, of opposite polarity to the ions detected, is used to attract these ions to the dynode. [[Secondary electron]]s are produced when the ions hit the dynode and are subsequently recorded via the detector used.

| Surface that is held at high potential so that ions striking the surface produce secondary charged particles that are subsequently detected.
| |
|
| |
| Note: For positive ions, the potential is negative and the secondary particles are electrons and negative ions. For negative ions, the potential is positive and the secondary particles are positive ions.
