SPM (in commissioning)

Scanning positron microscope

The Munich scanning positron microscope permits positron lifetime measurements with a lateral resolution in the μm range and within an energy range of 1 – 20 keV. Thus, this instrument enables the measurement of high-resolved 3D defect maps.

At present, the SPM is commissioned for future user operation.

SPM - scheme

The optical column of the SPM (light gray) connected to the SPM interface. Both is borne by a special frame construction (light yellow), which ensures the vibration decoupling via heavy damper (dark gray, only one shown).
