Samenvatting

A 2-D dust crystal levitated in the sheath of a modi-fied Gaseous Electronics Conference reference cell is manipulated by heating or cooling the lower electrode. The dust charge is obtained by measuring the global characteristics of the levitated crystal obtained from top-view pictures. From the force balance, the electric field in the sheath is reconstructed. From the Bohm criterion, we conclude that the dust crystal is levitated mainly above and just below the classical Bohm point.
