[[File:CLIC gas cooling vertex.png|thumb|Gas-cooling vertex streamlines|alt=|280x280px]]Strict requirements on the material budget for the vertex and tracking system do not allow the use of conventional [[liquid]] cooling systems for CLICdet. Therefore, it is proposed that a dry gas cooling system will be used for this inner region. Air gaps have been factored into the design of the detector to allow the flow of the [[gas]], which will be air or [[Nitrogen]].<ref name=Duarte-Ramos_Klempt_Nuiry_CLIC_CERN-2016>

}}</ref> To allow for effective air cooling, the average power consumption of the Silicon sensors in the vertex detector needs to be lowered. Therefore, these sensors will operate via a current-based power pulsing scheme: switching the sensors from a high to low power consumption state whenever possible, corresponding to the 50&nbsp;Hz bunch train crossing rate.<ref name="Blanchot_Dannheim_Fuentes_CLIC_CERN-2014">{{cite journal
