Web11 jan. 2016 · When implanting in a channeling direction, the spatial distribution of the channeled ions becomes markedly narrow, allowing a higher degree of control over the location of the nitrogen vacancy ( NV−) centers. A contamination layer on the ion entry surface reduces the fraction of channeled ions. WebThe bi-directional fan may be run seamlessly in both direction and flow rate to either cool or heat the cells, with forward, zero, and reverse air flow in order to achieve a desired air temperature. For example, the fan flow rate may be modulated by changing fan RPM (revolutions per minute) in both directions continuously or stepwise, as desired.
