HIGH SENSITIVITY MEASURING UNIT WITH A TRAP SYSTEM WITH PARALLEL DIPOLE LINES

摘要

A highly sensitive force measurement unit using a magnetic PDL trap system is provided. In one aspect, the force measurement unit includes: a PDL trap with a pair of dipole line magnets and a diamagnetic rod suspended above the dipole line magnets; an actuator with an extension rod near the PDL trap; a first examination object attached to the diamagnetic rod; and a second examination object attached to the extension rod, wherein the actuating element serves to move the second examination object to or away from the PDL trap by means of the extension rod. A method for force measurement using the present force measurement unit is also provided.
