2G cryogenic magnetometer
Installation and adaptive advancement of the cryogenic magnetometer 2G ENTERPRISES 755 HR. Programming, visualization and remote monitoring. Implementation of a cooling system (- 20°C) for measuring ice cores. Production of a module for the automatic measurement of the sample range. Installation of a compensation mechanism for the improvement of the zero-field.
Automatic sample assembly
Conception, planning and production of an automatic sample assembly for the 2G cryogenic magnetometer. Adaptation at an existing measuring system and programming. Scriptfile modules enable autonomous measurements for up to 96 specimens.
Magnetic susceptibility core logger
Design and manufacturing of an universal logger for measuring magnetic susceptibility. For the first time automated high resolution core measurements on split or whole cores are possible. Integration of a field survey loop and a repsonse sensor for high resolution surface measurements.
Programming
Developing and testing software to control and monitor measuring processes as well as data acquisition and storage using the graphic programming language LabVIEW (LABoratory Virtual instrument engineering Workbench).
CAD - CAM
Construction and documentation using a modern CAD system in 2D and 3D technology. Technical drawings and working models, support of entire production process and start-up.
Research boat “NERIDIS”
Extension of the light research boat "Neridis" (NERItic DIScoverer), equipped with DGPS, PC & WLAN access point, echosounder, deep towed option for magnetometers and intended electromagnetic sensor. Data recording and control by an embedded system. WLAN junction ensures real time access.
GEM-SHARK PROJECT
Development of a electromagnetic profiling system for high-resolution in-situ-measurements in marine systems. Design, development and realization of a fully equipped pressure housing (embedded system, network components various power and communication interfaces) with real-time communication link of standard signal transmission cable (armoured coax-cable up to 10.000m).
- HIGH-RESOLUTION ELECTROMAGNETIC IMAGING OF SUBSURFACE SEDIMENT PROPERTIES
- Real-time communication link
