Avalanche photo diodes

Avalanche Photo-Diodes (APD) are used for detection of very small doses of light or radiation with in some cases very high frequencies. Dependent on Design and application APDs can also be used for single photon counting. APDs are used in various fields in Science and Industry, such as Biology, Medicine, Chemistry, Aviation and more. iseg offers a wide range of power supplies with high stability and low noise in small packaging.


Photomultiplier tubes (PMT) are usually used for detection of weak doses of light in various different applications such as Particle Detectors for Neutrons and Muons (in combination with scintillator materials), medical technologies, optical spectroscopy, electron microscopy and many more. iseg offers standard solutions for many PMT types as well a customer specific designed power supplies for many PMTs and applications.

Solid-state detectors

Particle Detectors based on semiconductive materials, such as Silicon-, Germanium- and Cadmium zinc telluride-detectors and Silicon Photomultipliers are used for the proof and measurement of ionizing radiation. Depending on design and application of the detector, high voltage power supplies with high stability, low noise and specific protective features are necessary. iseg staff has a longstanding experience in design and manufacturing of high voltage power supplies for semiconductive particle detectors and is offering standard products as well as customer specific supplies.

Dosimeters and dose rate meters

Dosimeters and dose rate meters are used for the measurement of radiation doses in radiation protection and by relief units such as fire brigades, police and military(NBC). Depending on Design and application high voltage power supplies are necessary. iseg is providing several manufacturers of dosimeters and dose rate meters.

gas ionisation detectors

Gas ionisation detectors, such as Ionisation Chambers, Straw-Tubes, Wire Chambers, Resisitive Plate Chambers, Gas Electron Multipliers, MicroMegas and more are widely used in different applications for the detection of ionising radiation. For proper operation these detectors often need reliable high voltage power supplies with very high stability and low noise. Depending on detector type, specific protection to prevent damage of the detector can also be necessary. iseg has longstanding experiences with various detector types and a wide product range from single channel devices to systems with several thousands of channels.

Electrostatic Lenses

electrostatic lenses are used for deviation,  focus and control of ion beams. Therefore, depending on the requested reaction, different electromagnetic fields are applied. For the generation of the electromagnetic fields high-voltage power supplies are necessary.  iseg Spezialelektronik GmbH has several years of experience in this application and can use ta wide range of basic products for adaptations.

Mass Spectrometry

For analysis of unknown substances in Biology, Chemics and Medicine, Mass Spectrometers are widely used. Depending on design and application of the mass spectrometer, high voltage power supplies with very high stabilities are necessary for the required analyses. iseg offers standard solutions as well as customer specific designed power supplies.

Particle filter

Particle filter are electrostatic filter and are used for the filtering of exhaust gas, especially in set ups with exhaust particles with big dimensions (e.g. wood gas facilities). The necessary high voltage power supplies have to be ruggedizzed, reliable and easy to install and use. iseg has a longstanding experience in this field and offers a wide range of solutions.

Capacitor Charging

capacitor charging often has high requirements regarding repeatability and constant charging current. iseg has much experience in adapting hogh voltage power supplies for capacitor charging applications and has wide range of already completed basic products.

Electrostatic Chuck

Used for holding wafers during process in vacuum. An electrostatic force clamps the wafer.

Electron Beam Systems

Electron Beam Systems are widely used in Science and Industry (i.e. Electron beam welding, surface-harden, sterilization, perforation, electron beam lithography). For acceleration and deflection of electrons high voltage power supplies are necessary.

Ion Implantation

Ion Implantation is used for insertion of Ions into specific materials (doping) to achieve a specific change of the characteristics of the basic material. This method often used in the semiconductor industry. Several steps of this method (i.e. Acceleration, Separation of Ions, Deflection of Ions) require high voltage power supplies.

Plasma creation

For generation and maintenance of electron plasma for usage in Science and Industry High Voltage Power Supplies with high output power are often used. Usually for Ignition high voltages and for maintenance high current is necessary. iseg Spezialelektronik GmbH has already done several adaptations of basic products for this application.

Material Separation

To separate different materials one from another, one often uses electrical fields, generated by high voltage power supplies. For example to separate and to recycle the materials existing in shreddered electronics waste.

cable test facility

Systems for cable testing, for example for validation of proof voltage, defects analysis, defects repair or diagnosis of additional parameters are fields of usage of iseg high voltage power supplies with output voltages up to 80kV. iseg has a longstanding experience and several cooperations with industrial and scientific partners in this field.

HV Testing

During product or component development in science and industry, sometimes high voltage tests are necessary. These are done to measure the reaction or the durability of components or whole products to exposure to high voltage in short or long time scales. For different setups, high voltage supplies from iseg Spezialelektronik GmbH can be used.

X-Ray Tubes

X-Ray tubes are used for various applications in Science (i.e. Analysis of Materials), Industry (i.e. thickness measurement) and Medicine (i.e. Diagnostics). Often high voltage power supplies with different specifications according to the application are needed for the generation of X-Rays.


Applying electromagnetic fields, electrophorese is used for separation and analysis of mixtures of substances in Biology, Chemistry and Medicine. Depending on the setup of the experiment, high voltage power supplies are used.
