|2020-07-01.||Magnus Holmsten||RISE Research Institutes of Sweden||The national laboratory for temperature at RISE realizes ITS-90 from -189.3442 ░C to 2600 ░C and make accurate traceable temperature measurements with different types of sensors for a broad area of applications within various research projects at RISE.
Furthermore RISE have developed a transportable refractometer, partly within earlier EMPIR-projects, capable of asses density and pressure with very high precision and accuracy.
|2020-07-01.||Aleksandra Foltynowicz||Department of Physics, Umeň University||High-resolution near- and mid-infrared comb-based Fourier transform spectroscopy referenced to absolute pressure/density standard. Experience in multispectral fitting with refined line shape models.|
|2020-06-25.||Markku Vainio||University of Helsinki (UH)||UH has a broadly tunable near-infrared (1520 to 1630 nm) laser, which is phase phase locked to a fully stabilized frequency comb for comb-assisted spectroscopy and which can be combined with CRDS and other spectroscopy methods used in the UH lab. In addition to two near-infrared combs that cover wavelengths between 1 and 2 Ám, UH has two fully stabilized mid-infrared combs that can be operated between 3 and 4 Ám and can be used for direct comb spectroscopy, with an option for comb-assisted spectroscopy. The laboratory is also equipped with a Bruker ISF 120HR FTIR spectrometer, which however is quite old and not set up for the most accurate measurements.|
|2020-06-25.||Daniel Lisak||UMK||UMK has two frequency comb assisted CRDS spectrometers, for visible and near-IR wavelengths and broadband comb-based FT spectrometer for near- and mid-IR. The near-IR CRDS spectrometer also uses the cavity mode width (CMWS) and cavity mode dispersion (CMDS) spectroscopic technique in which both axes of the spectrum are linked to the primary frequency standard. Spectrometers are equipped with high-accuracy pressure and temperature sensors.
UMK has experience in spectral line-shape theory and has its own software to for fitting spectra with advanced line shape models, including Hartmann-Tran (HT) and beyond HT models.
|2020-06-15.||GANG LI||PTB||1)PTB has two large FTIR infrastructure inherited from EMRP EUMETRISPEC program and being constantly tuned and upgraded with latest technology advances. The infrastructure is capable of measuring high resolution spectra up to 0.0015 cm-1 . The spectrometers are coupled with temperature variable cells at different path lengths. The infrastructure is suitable for accurate spectroscopic temperature determination defined in the objectives of the SRT.
2)PTB has its own spectral fitting software including many modern functionalities, including the IUPAC recommended Hartmann-Tran line profiles and line-mixing, which are essential for this SRT. The software has a customized variant to determine rotational temperature from the line intensity distribution of an entire rovibrational band.
3) PTB has experience working with high accuracy ab initio line lists on CO which has a clear advantage of highly precise relative line intensity distribution within a ro-vibrational band.
