Publication number: 20230184696Abstract: The present invention relates to a method to reduce drift of a sample and/or its image in a microscopy system, wherein the method comprises determining an expected thermal drift of the sample, and compensating for the drift of the sample and/or its image based upon the expected thermal drift. The present invention also relates to a corresponding microscopy system and a computer program product to perform the method according to the present invention.Type: ApplicationFiled: December 15, 2022Publication date: June 15, 2023Applicant: FEI CompanyInventors: Hugo VAN LEEUWEN, Edwin VERSCHUEREN, Johannes VAN DEN OETELAAR, Martin VERHEIJEN, Ronald LAMERS, Marcel VAN WENSVEEN

Publication number: 20220404247Abstract: Apparatus and methods are disclosed for vibration-free cryogenic cooling, suitable for TEM and other analytic equipment. A thermal battery includes one or more of: a cryocooler, a thermal switch, a thermal cold storage reservoir, and a cold finger. The thermal reservoir is mounted outside a sample chamber. The cold finger provides thermal coupling between the reservoir and a sample holder inside the sample chamber. In varying embodiments, sample holder and sample temperatures are regulated by a heater or by an inline variable thermal resistor. Cyclic phased operation includes cooling the reservoir, decoupling the cryocooler from the reservoir, and temperature-regulated passive vibration-free thermal energy extraction from sample to reservoir. The described system delivers a stand time of 12 hours at 20 K. Temperature regulation, a hybrid thermal switch, damping of thermal fluctuations, and material selection are described.Type: ApplicationFiled: June 21, 2021Publication date: December 22, 2022Applicant: FEI CompanyInventors: Ronald Lamers, Hans Persoon, Alphons Theophile Augusta Maria de Waele, Theo Ruijl, Hugo van Leeuwen

Patent number: 9865427Abstract: A user interface for operation of a scanning electron microscope device that combines lower magnification reference images and higher magnification images on the same screen to make it easier for a user who is not used to the high magnification of electron microscopes to readily determine where on the sample an image is being obtained and to understand the relationship between that image and the rest of the sample. Additionally, other screens, such as, for example, an archive screen and a settings screen allow the user to compare saved images and adjust the settings of the system, respectively.Type: GrantFiled: May 5, 2015Date of Patent: January 9, 2018Assignee: FEI CompanyInventors: Martinus Petrus Maria Bierhoff, Bart Buijsse, Cornelis Sander Kooijman, Hugo Van Leeuwen, Hendrik Gezinus Tappel, Colin August Sanford, Sander Richard Marie Stoks, Steven Berger, Ben Jacobus Marie Bormans, Koen Arnoldus Wilhelmus Driessen, Johannes Antonius Hendricus W.

Patent number: 8309921Abstract: A compact electron microscope uses a removable sample holder having walls that form a part of the vacuum region in which the sample resides. By using the removable sample holder to contain the vacuum, the volume of air requiring evacuation before imaging is greatly reduced and the microscope can be evacuated rapidly. In a preferred embodiment, a sliding vacuum seal allows the sample holder to be positioned under the electron column, and the sample holder is first passed under a vacuum buffer to remove air in the sample holder.Type: GrantFiled: February 1, 2011Date of Patent: November 13, 2012Assignee: FEI CompanyInventors: Martinus Petrus Maria Bierhoff, Bart Buijsse, Cornelis Sander Kooijman, Hugo Van Leeuwen, Hendrik Gezinus Tappel, Colin August Sanford, Sander Richard Marie Stoks, Steven Berger, Ben Jacobus Marie Bormans, Koen Arnoldus Wilhelmus Driessen, Johannes Antonius Hendricus W.

Publication number: 20100230590Abstract: A compact electron microscope is robust, simple to operate, and preferably requires no special utilities. Imaging can begin shortly after a sample is inserted. A preferred simplified design includes permanent magnets for focusing, lack a vacuum controller and vacuum gauge, and uses a backscattered electron detector and no secondary electron detector.Type: ApplicationFiled: June 7, 2007Publication date: September 16, 2010Applicant: FEI COMPANYInventors: Mart Petrus Maria Bierhoff, Bart Buijsse, Cornelis Sander Kooijman, Hugo Van Leeuwen, Hendrik Gezinus Tappel, Colin August Sanford, Sander Richard Marie Stoks, Steven Berger, Ben Jacobus Marie Bormans, Koen Arnoldus Wilhelmus Driessen, Johannes Antonius Hendricus W.
