The active magnetic field compensation system MFC was developed specifically for electron microscopes and electron beam lithographs based on many years of practical experience. These are mainly used in the areas of research, development, production and quality control. To achieve the best possible results, they need optimal magnetic environmental conditions.<\/p>\n

A passive shielding chamber made of nickel-iron alloy (Mu-metal, Permalloy) is very complex and costintensive, alternatively an active compensation system can be used with little effort. It is also possible to operate a less expensive passive shielding chamber in combination with an active compensation system, thus both advantages can be used.<\/p>\n

The system processes and compensates for static as well as alternating electromagnetic fields in the frequency range from 0 Hz to 20,000 Hz within a field strength of \u00b1 100 \u03bcT (\u00b1 1 G).<\/p>\n
In this process a reduction of the magnetic interference field by a factor of 1,000 (60 dB) is achieved at the location of the control sensor in the frequency range from 0 Hz to 1,000 Hz.<\/p>\n
This means, for example, an interference field with 1 \u03bcT (10 mG) is reduced to 1 nT (10 \u03bcG).<\/p>\n

With the appropriate space coil design and the corresponding control device, very strong magnetic fields up to the
earth’s magnetic field can be compensated, whereby with the increase of the frequency of the interference field the
power of the generated counter field decreases.<\/p>\n
So that the entire earth’s magnetic field is not compensated, offset operation is possible with both control devices.
In the same way, the compensation of the constant field can be switched off.<\/p>\n

Der Magnetfeldsensor und das Hightech-Ger\u00e4t, das magnetisch abgeschirmt werden soll, befinden sich innerhalb der Raumspule.<\/p> Um einen gro\u00dfen Reduktionsbereich innerhalb der Raumspule zu erreichen, wird in der Regel die Raumspule in den Kanten des Raumes verlegt. Falls der Raum zu gro\u00df ist, kann ein freitragendes Ger\u00fcst f\u00fcr die Installation der Raumspule verwendet werden. Falls mehrere Ger\u00e4te in einem Raum magnetisch abgeschirmt werden m\u00fcssen, k\u00f6nnen weitere Kompensationsanlagen direkt nebeneinander installiert und betrieben werden.<\/p> Folgende Darstellung zeigt das Prinzip des r\u00e4umlichen Aufbaus der Raumspule mit dem Magnetfeldsensor:<\/p> [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=\"1_2,1_2\" _builder_version=\"4.20.2\" _module_preset=\"default\" global_colors_info=\"{}\"][et_pb_column type=\"1_2\" _builder_version=\"4.20.2\" _module_preset=\"default\" global_colors_info=\"{}\"][et_pb_image src=\"https:\/\/mende-systemelektronik.com\/wp-content\/uploads\/2023\/03\/Mende-Systemelektronik-Raumspule-740-1.jpg\" alt=\"Mende Systemelektronik - Raumspule\" title_text=\"Mende Systemelektronik - Raumspule\" align=\"center\" _builder_version=\"4.20.2\" _module_preset=\"default\" width=\"60%\" width_tablet=\"60%\" width_phone=\"auto\" width_last_edited=\"on|phone\" custom_margin=\"||30px||false|false\" global_colors_info=\"{}\"][\/et_pb_image][\/et_pb_column][et_pb_column type=\"1_2\" _builder_version=\"4.20.2\" _module_preset=\"default\" global_colors_info=\"{}\"][et_pb_text _builder_version=\"4.20.2\" _module_preset=\"default\" global_colors_info=\"{}\"]<\/p> Anordnung der einzelnen Spulen f\u00fcr jeden Feldvektor, farblich dargestellt.<\/p> Magnetische Achsausrichtung des Magnetfeldsensors zur Raumspule.<\/p> Gegensinnigkeit der Magnetfeldrichtung f\u00fcr jeden Feldvektor, dadurch erfolgt die Ausl\u00f6schung des magnetischen Der Magnetfeldsensor befindet sich zusammen mit dem Hightech-Ger\u00e4t innerhalb der Raumspule.<\/p> [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=\"4.20.2\" _module_preset=\"default\" background_color=\"#e7e7e7\" custom_margin=\"||||false|false\" custom_padding=\"25px|25px|25px|25px|false|false\" border_width_all=\"1px\" border_color_all=\"#0070c0\" global_colors_info=\"{}\"][et_pb_column type=\"4_4\" _builder_version=\"4.20.2\" _module_preset=\"default\" global_colors_info=\"{}\"][et_pb_text _builder_version=\"4.20.2\" _module_preset=\"default\" global_colors_info=\"{}\"]<\/p> [\/et_pb_text][dvmd_table_maker tbl_title_mode=\"on\" tbl_title_text=\"Steuerger\u00e4t MFC 45 \/ MFC 90\" tbl_column_header_count=\"0\" tbl_row_header_count=\"0\" tbl_responsive_break_by=\"row\" tbl_chead_cell_color=\"RGBA(255,255,255,0)\" _builder_version=\"4.20.2\" _module_preset=\"default\" tbl_title_level=\"h4\" tbl_chead_text_font=\"|700|||||||\" tbl_chead_text_text_color=\"#0070c0\" global_colors_info=\"{}\"][dvmd_table_maker_item col_content=\"Arbeits- und Messbereich
