Special Features

  • "Ultra Stabilized (TM)" wide bore magnet at 17.64 T
  • resonance frequency of 1H: 750 MHz
  • 2 RF-channels to produce strong RF-pulses (more than 1000 W) and 1 RF-channel 500 W
  • full digital signal generation (SGU) provides amplitude waveforms ("shaped pulses") and phases can be switched virtually without delay.
  • digital deuteron lock of the magnetic field
  • fast digitizer (up to 10 megasample per second) and broadband receiver (up to 5 MHz)
  • oversampling and digital filtering
  • (CP)MAS up to 7 kHz (7 mm rotor), up to 15 kHz (4 mm rotor) and up to 35 kHz (2.5 mm rotor)
  • triple resonance MAS
  • the RF-pulses can be synchronized with the MAS rotation
  • double rotation (DOR) is possible
  • goniometer probehead 4.2 K to 300 K, with an additional goniometer axis (perpendicular to the first goniometer axis and the static magnetic field (+/- 10 adjustment))
  • gradient pulses using a current of max. 10 A are possible
