AVANCE-II-360 MHz (8.5T/89 mm and 4.7T/89 mm) with probeheads that are tailored in NICPB for solid state NMR experiments, including cryoMAS (10–300 K) probehead for a 1.8×15 mm rotor, high temperature (300–1200 K) probehead for static samples and MAS-probehead for large 10 mm rotors.

Terahertz Spectroscopy and Low Temperature Physics facilities

THz spektromeeter SPS200 (Sciencetech) that can be used with two different measurement devices:

1) TeslaFIR – magnetic field of 0 …  +/- 17 T, with a 0.3K bolometer, measurement range 2.5 – 200cm^–1, that enables the probe temperature to reach the temperature range 2.5-300K and measurements encompass reflection and transmission (Faraday and Voigt configuration),

2) milliK-TeslaFIR – magnetic field 0 … +/- 12T, with a 0.3K bolometer, measurement range 2.5 – 100cm^–1, that enables to measure THz transmission in the temperature region of 150 mK kuni 5K.

Fourier’ spectrometer Vertex 80v (Bruker), equipped with two sample cryostats (‘cold finger’  5-400K, ‘exchange gas’ 2-300K) and allows for zero magnetic field measurements in the range of 10-50 000 cm^–1 and transmission, reflections and ATR spectra.

Helium station equipment

He liquefier CTi-1410 (1979) with piston detander working with two piston compressors, 20 kW each. Productivity: 20 l liquid He per hour using pure gas and 15 lph using impure recovered gas, which is prepurified during the same procedure.

Cryo Unit provides the maintenance and repairing of cryo and vacuum apparatus and devices as well.

The NICPB Helium station is the only one in the Baltic States and equips the University of Tartu and Tallinn University of Technology with liquid helium.

Nonlinear Spectroscopy femtosecond laser

The nonlinear optics lab employs a femtosecond pulsed excitation laser (PHAROS, Light Conversion UAB) combined with a optical parametric amplifier (Orpheus-HE, Light Conversion UAB) and second harmonic generator to produce < 150 fs pulses over a tunable wavelength range of 320 – 2600 nm, with an adjustable repetition rate ≤ 6 kHz. Typical pulse energies of 66 – 150 μJ are ideally suited for nonlinear optical spectroscopy techniques such as two-photon excited fluorescence (2PEF) in liquid samples.
