The system, the magnet:

Bruker AVANCE Ultra Shield 500 widebore

Magnetic field of 11.74 T

Our equipment comprises:

Static wide-line probes
- for high and low frequency measurements
- for high temperature measurements, up to T = 500 K
- for low temperature measurements, down to T = 4 K

Automatic Tuning Matching Goniometer (ATMG) probe systems [1]: special designed static wide-line probes for measurements of very wide frequency ranges, equipped with piezoelectric engines for automatic tuning and matching as well as an one-cycle goniometer for orientation dependent NMR measurements of magnetically aligned powder samples.

A double resonance probe for measurements of close frequencies [2].

Magic Angle Spinning (MAS) equipment for double and triple resonance probes:
- 4.0 mm (max. rotation frequency 15 kHz)
- 2.5 mm (max. rotation frequency 35 kHz)
- 2.5 mm (max. rotation frequency 35 kHz) for close frequencies [2]
- 1.3 mm (max. rotation frequency 70 kHz)
