Description
Magnetic measurements of single magnets are essential to making a high-quality insertion device. Kyma R&D lab is constantly working on improving these measurements and looking for new ways of extracting information that could be used for further optimizations of the insertion device manufacturing process.
R&D lab at ESRF successfully demonstrated that the signal measured from a stretched wire system is analogous to the absorption signal of the x-rays used in tomography and can be used to reconstruct 2D magnetic field maps. Following success of the ESRF demonstrator. Kyma lab build a similar system, consisting of a dedicated stretched wire bench, a rotary stage and a Keithley Nanovolt meter. System is controlled by a Raspberry Pi 4 single board computer. Python is used both for motion control/data acquisition and data analysis. Here we present design of the system, principles of operation, first results and possible future usage of the system.
