Tip Enhanced Raman Scattering (TERS, nanoRaman) is the technique for enhancement of weak Raman signals and for superresolution Raman imaging with spatial resolution less than 10 nm. As a result of comprehensive research performed together with NTMDT SI customers and partners, we are now able to offer to AFMRaman customers mass produced reproducible TERS probes. TERS imaging requires prolonged tipsample contact at each scanning point but Contact AFM is destructive for both the tip and the sample. Thereby, HD mode is a superior technique for cantilevertype TERS since it noticably increases the tip lifetime and makes possible TERS imaging of soft, loose and fragile samples. Vacuum measurements in amplitude modulation (AM) mode requires unacceptably low scanning speeds because of extremely high Qfactor of AFM probes. Being a nonresonant mode, HD mode allows at least 10 times faster imaging speed.

This magnetic system is specially designed for non-destructive testing of pumped vacuum devices, that required the creation of a uniform magnetic field not only in the center of the operating bore, but in the toroidal region of large size. The system is assembled on the basis of NdFeB permanent magnets. Field direction:axial Field uniformity in a specified toroidal area:up to ±2% Magnetic flux density (for existing modifications):from 0.1 to 0.4 T Bore diameter:120 mm and more
