Previously undescribed oligosaccharides in bovine cheese whey permeate were characterized by a combination of nanoelectrospray Fourier Transform Ion Cyclotron Resonance (nESI-FTICR) mass spectrometry and matrix-assisted laser desorption/ionization Fourier transform ion cyclotron resonance (MALDI-FTICR) mass spectrometry. Oligosaccharide composition was elucidated by collision-induced dissociati...

This report compares results ion-cyclotron range of frequencies (ICRF) plasma production at hydrogen minority regime in Uragan-2M (U-2M) and Large Helical Device (LHD). The condition the presence fundamental harmonic ion cyclotron resonance zone for inside column should be fulfilled this method. scenario is successful both machines weakly sensitive to variation concentration H2+He gas mixture. ...

Detachment of heme prosthetic groups from gaseous myoglobin ions has been studied by collision-induced dissociation and infrared multiphoton dissociation in combination with Fourier-transform ion cyclotron resonance mass spectrometry. Multiply charged holomyoglobin ions (hMbn+) were generated by electrospray ionization and transferred to an ion cyclotron resonance cell, where the ions of intere...

The 88-Inch Cyclotron began regular operation with the ECR (Electron Cyclotron Resonance) source in January 1985. Since then about 80% of the cyclotron operating schedule has been with the ECR source. The light-ion filament source is used only for runs two or more shifts in length using proton, deuteron, 3He, or alpha beams. Occasionally the polarized ion source is used. The heavy-ion PIG sourc...

A new concept to assist in the extraction of ion beams from an electron cyclotron resonance ion source ~ECRIS! by the injection of an electron beam from the extraction side into the ion-source plasma is proposed. In this article, the construction of a test setup is described and first results of experiments with this setup at the 14 GHz ECRIS of the Frankfurt ECRIS-~ve!RFQ facility are reported...

A commercial, position-sensitive ion detector was used for the rst time for the time-ofight ion-cyclotron resonance detection technique in Penning trap mass spectrometry. In this work, the characteristics of the detector and its implementation in a Penning trap mass spectrometer will be presented. In addition, simulations and experimental studies concerning the observation of ions ejected from ...
