    Abstract: The invention relates to a method of determining an aberration of a charged particle microscope. The method comprises a step of providing a charged particle microscope that is at least partly operable by a user. Then, a set of image data is obtained with said charged particle microscope. The image data is processed to determine an aberration of said charged particle microscope. According to the invention, said set of image data is actively obtained by a user. In particular, the image data may be obtained during normal operation of the microscope by a user, which may include navigating and/or focusing of the microscope. Thus, the set of image data is acquired by said user, and not by the controller thereof. This allows background processing of an aberration, and aberration correction during use of the charged particle microscope. The invention further relates to a charged particle microscope incorporating the method.

    Abstract: Disclosed is a method of using a charged particle microscope for inspecting a sample mounted on a sample holder. The microscope is equipped with a solid state detector for detecting secondary particles emanating from the sample in response to irradiation of the sample with the primary beam, with the solid state detector in direct optical view of the sample. In some embodiments, the sample is mounted on a heater with a fast thermal response time. The method comprises contactless measurement of the temperature of the sample and/or sample holder using the solid state detector.

    Abstract: The invention relates to a charged-particle apparatus having a charged particle source with an optical axis; a magnetic immersion lens comprising a first lens pole and a configurable magnetic circuit; and a first sample stage movable with respect to the optical axis. The apparatus has a first configuration to position the sample, mounted on the first stage, with respect to the optical axis and a second configuration, having a second lens pole mounted on the first stage and intersecting the optical axis, equipped with a second sample stage to position the sample between the two lens poles and is movable with respect to the optical axis, causing the optical properties of the magnetic immersion lens to differ in the two configurations, and can, in the second configuration, be changed by positioning the second lens pole using the first stage, thus changing the magnetic circuit.
