The Langmuir probe method is used for measurement. The relative simplicity of the method and the possibility of dispersion of high power on the probe allow its application for the investigation of high-power electron beams. The key element of the method is a rotating thin tungsten wire, which intersects the beam transversely on its axis and collects part of the current by itself. The signals, which are registered in the DIABEAM as a voltage, were taken in the form of amplitude. The conversion of the probe current into the distribution along the beam radius was realised using the Abel's method. A voltage-current characteristic was built for the beam current. The local electron density as well as the electron temperature, the floating potential and the plasma potential were measured and calculated by means of this characteristic.}, language = {en} } @inproceedings{ReisgenSchleserAbdurakhmanovetal.2009, author = {Reisgen, Uwe and Schleser, Markus and Abdurakhmanov, Aydemir and Gumenyuk, Amdrej V.}, title = {Measurement method of electron beam plasma parameters by non-vacuum electron beam welding}, series = {Beam technologies \& laser application : proceedings of the VI international conference, Saint Petersburg, Sept. 23-25, 2009}, booktitle = {Beam technologies \& laser application : proceedings of the VI international conference, Saint Petersburg, Sept. 23-25, 2009}, editor = {Turichin, G.}, publisher = {Politechnical Univ.}, address = {Saint Petersburg}, organization = {Russian Academy of Science}, pages = {259 -- 267}, year = {2009}, language = {en} } @article{KaemperEhrfeldHesseletal.1997, author = {K{\"a}mper, Klaus-Peter and Ehrfeld, W. and Hessel, V. and Lacher, M.}, title = {Market oriented development and production of microdevices.

During handling operations of the powder material, several influencing factors can affect the properties of the powder material and therefore directly influence the processability during manufacturing. Contamination by moisture due to handling operations is one of the most critical aspects of powder quality. In order to investigate the influences of powder humidity on LPBF processing, four materials (AlSi10Mg, Ti6Al4V, 316L and IN718) are chosen for this study. The powder material is artificially humidified, subsequently characterized, manufactured into cubic samples in a miniaturized process chamber and analyzed for their relative density. The results indicate that the processability and reproducibility of parts made of AlSi10Mg and Ti6Al4V are susceptible to humidity, while IN718 and 316L are barely influenced.}, language = {en} }
