Electrical discharges caused by opening contacts in an ignitable atmosphere – Part II: Spectroscopic investigation and estimation of temperatures

Autor: Tobias Runge, Carsten Uber, Jens Brunzendorf, Udo Gerlach, Michael Kurrat

Publikováno v: Journal of Loss Prevention in the Process Industries. 61:213-219

Electrical discharges are a potential source of ignition in explosive atmospheres. Spectroscopic investigations of the radiation emitted during such discharges give a better understanding of the processes that take place during ignition. The discharg

Influence of thermal shock of piezoelectric pressure sensors on the measurement of explosion pressures

Autor: Tim Krause, Jens Brunzendorf, Mirko Meier

Publikováno v: Journal of Loss Prevention in the Process Industries. 71:104523

Piezoelectric pressure sensors are susceptible to changing temperatures, because resulting mechanical deformations of the sensor membrane and housing may exert a positive or negative force on the piezo crystal, thus changing the reading of this senso

First measurements of nitrous oxide self-broadening and self-shift coefficients in the 0002-0000 band at 2.26μm using high resolution Fourier transform spectroscopy

Autor: Anton Serdyukov, Olav Werhahn, Jens Brunzendorf, Viktor Werwein, Volker Ebert

Publikováno v: Journal of Molecular Spectroscopy. 323:28-42

Nitrous oxide (N2O) is one of the most important greenhouse gases in the terrestrial atmosphere and is routinely measured with ground-based FTIR networks like the Total Carbon Column Observing Network (TCCON). A spectral window for the TCCON retrieva

High-resolution Fourier transform measurements of line strengths in the 00sup0/sup2-00sup0/sup0 main isotopologue band of nitrous oxide

Autor: Viktor, Werwein, Jens, Brunzendorf, Gang, Li, Anton, Serdyukov, Olav, Werhahn, Volker, Ebert

Publikováno v: Applied optics. 56(11)

Nitrous oxide (Nsub2/subO) is a key greenhouse gas and a major ozone-depleting anthropogenic pollutant monitored by the total carbon column observing network (TCCON) in the 00sup0/sup2-00sup0/sup0-band of its main isotopologue. Here, we present highl

Nitrous oxide line positions in the 0002-0000 band at 2.26 µm as test case for high-resolution FTIR-spectrometer stability

Autor: Volker Ebert, Olav Werhahn, Anton Serdyukov, Gang Li, Viktor Werwein, Jens Brunzendorf

Publikováno v: Imaging and Applied Optics 2016.

2.26 µm 14N2 16O line positions referenced to CO 2-0 were determined and used to analyze linearity and drift of the wavenumber scale of a high-resolution Bruker 125 FTIR-spectrometer over a period of one year.

Rod phantom dimensions - does size matter?

Autor: P. Ambrosi, Jens Brunzendorf

Publikováno v: Radiation Protection Dosimetry. 135:221-225

The international standard ISO 4037-3:1999 recommends a cylindrical polymethyl methacrylate rod phantom of 300 mm length and 19 mm diameter for the calibration of extremity dosimeters worn on the finger. No tolerances are stated. This paper investiga
