Characterisation of NEG St122 sorption properties has been ordered by PerkinElmer Optoelectronics, Wiesbaden, Germany in the frame of long-term cooperation contract with IMT. The NEG samples were selected from the production of channel photomultipliers and analysed by improved standard method, which was introduced at IMT beginning of 2006. Namely, when using a quadrupole mass spectrometer in dynamic mode to analyse the background atmosphere after completing the hydrogen sorption test, several samples showed increased methane formation and in some cases non-negligible argon emission as well.

COBISS.SI-ID: 718762Characterisation of indium eutectic solders InSn and InBi has been ordered by PerkinElmer Optoelectronics, Wiesbaden, Germany in the frame of long-term cooperation contract with IMT. The In solder samples were selected from the production of channel photomultipliers. The main part of characterisation consists of outgassing measurement of liquid In-alloy solders during mechanical stirring in ultrahigh vacuum. Quantity of released gases is measured using an inert spinning rotor gauge in static mode, but their absolute composition using a calibrated quadrupole mass spectrometer in dynamic mode.
