Expert Group Microprocessor Systems and Analog Instrumentation (MSA)

MSA_Querschnitt

The group is developing customized electronic modules and systems for applications in the fields of measuring and control technology as well as data acquisition and processing. Emphasis is put on high-precision analog circuits for signal conditioning, microcontroller-based sensor devices, and complex multichannel measurement and monitoring systems.

Key competences are: 

  • Analog and digital circuit design, high-frequency technology, and optoelectronics
  • Hardware and firmware design for microcontroller-based embedded systems
  • Development of application-specific measurement technology for (large-scale) experiments

Our activities cover the complete development process from conceptual design to hardware and software development up to commissioning of the completed systems.
We test the complete system in our RF, optical and EMC characterization facilities.

High power LED modules

Many industrial processes today are based on the purposeful use of light. At IPE researchers develop high power density light engines usable for lacquer curing in printing machines, for instance. For this purpose many high-power LED chips are mounted tightly together into modules which are efficiently cooled by special water cooling blocks. The main challenges include a thermal path with very low resistances between the LED junction and the cooling water as well as a reliable electrical and mechanical connection between the components.

OpticalDataTransmission

Tbit/s Optical Data Transmission in particle physics and photon science

IPE develops a high-speed and energy-efficient optical data transmission system tailored for future detectors. Within this system, electrical input signals are converted into optical output signals by the use of silicon-based electro-optic chips developed at KIT. Researchers at IPE focus on the investigation of electrical and optical packaging, of modulator design, operability and reliability at low temperatures and strong magnetic fields, and optical link aggregation.

MIPAS – Measurement of Trace Gases in the Stratosphere

 

For the MIPAS climate experiment conducted by the Institute of Meteorology and Climate Research, IPE develops complex control and data acquisition systems. The MIPAS instrument measures the weak infrared radiation of trace gases in the stratosphere. These trace gases are considered precursory substances of ozone formation, for instance.


Caribic
CARIBIC

CARIBIC – Ozone Photometer

On behalf of the Institute of Meteorology and Climate Research – Atmospheric Trace Gas and Remote Sounding Division, the electronics and data acquisition were developed and fabricated for an ozone photometer. The ozone photometer serves to measure ozone on a Lufthansa passenger aircraft under the CARIBIC project. The measurement principle is based on the absorption of UV radiation by ozone.


KATRIN Detektorsystem
KATRIN - Detector system

KATRIN - KArlsruher TRitium Neutrino Experiment

The KATRIN experiment will intended to measure the mass of the electron neutrino particle to a yet unequalled accuracy. KATRIN will therefore be the most sensitive weighing machine in the world. IPE is deeply involved in almost any electronics system of KATRIN and is responsible for a number of tasks in the domains of control technology, data acquisition, detector design, but also in a superordinate level for the coordination of interfaces between the control systems of KATRIN sub-units.

HEPHAISTOS

 

The microwave oven HEPHAISTOS developed at KIT is a new heating system for e.g. thermosetting of carbon-fiber-reinforced plastic (CFRP). As the heat is generated inside the material volume, the microwave heating process is fast and energy-efficient. Both are important advantages compared to conventional heating techniques. The system has a unique hexagonal structure and uses up to 36 magnetrons, providing a rather uniform distribution of the electromagnetic field. To further improve the homogeneity of the resulting temperature distribution within the heated components  advanced control methods are being applied e.g. model predictive control (MPC), and magnetronpower is adjusted accordingly to individual magnetrons. The control system shall be adaptive to support components with different materials and geometry shapes without relying on specific parameter values.


Current Projects
