The topics include the history of ion mobility spectrometry, sample introduction methods, ion injection and pulsed sources, drift tubes, the ion mobility spectrum, ion mobility-mass spectrometry, ion characterization and separation: the mobility of gas-phase ions in electric fields, control and effects of experimental parameters, detecting explosives with IMS, chemical weapons, environmental monitoring, biological and medical applications, and current assessments and future developments.
Currently, the power supplies, modulators and klystrons are operating; the ion source and radiofrequency quadropole sections are producing at rated capacity (28 mA of beam current); the beam line is installed and vacuum tested; the drift tubes are installed; and the DTL tanks are in testing prior to 30 MeV operation.
