中文摘要	We present a new generation of a scanning microSQUID microscope operating in an inverted dilution refrigerator. The microSQUIDs have a size of 1.21m and a magnetic flux sensitivity of 120 and thus a field sensitivity of 550. The scan range at low temperatures is about 80 m and a coarse displacement of 5 mm in x and y direction has been implemented. The microSQUID-to-sample distance is regulated using a tuning fork based force detection. A microSQUID-to-sample distance of 420 nm has been obtained. The reliable knowledge of this distance is necessary to obtain a trustworthy estimate of the absolute value of the superconducting penetration depth. An outlook will be given on the ongoing direction of development.
