XAMS Team Members 1999 (not complete), front: Rupert Perera, Wayne Stolte and Gunnar Öhrwall, standing: Dennis Lindle, Ivan Dominguez, Oliver Hemmers, Lan Dang and Colin.

Dennis Lindle (PI) of the XAMS team in front of the electron-TOF system. The electronic for the data aquisition is in the blue rack at the right and the controll electronic for the vacuum components is at the left (beige rack). The electron-TOF system is shown in full operation at beamline 8.0 at the ALS.


Team Member Oliver Hemmers at one of many beam times at beamline 8.0 with the electron-TOF system can take it easy when the data is rolling in.


The final JAR Samson Group (1997), Professor emeritus James A.R. Samson (sitting) with his former post-docs Wayne Stolte (left) and Ying Lu (right) from the University of Nebraska, Lincoln. Behind is their experimental setup on beamline 9.0.1 at the ALS. They were in the process of testing their new developed electron-TOF analyzer.


Former XAMS Team Member David Hansen is having a good time playing Civilization --- I mean taking data.


Summer student Abbas Risvi


Collaborator Burkhard Langer (left) from the Max-Born-Institute in Berlin, Germany developed the data aquisition software for the electron-TOF system talking with team member Oliver Hemmers who designed and built this electron-TOF system.


Former collaborating Team Members Dragan Lukic (left), graduate student with Ivan Sellin from the UT, Tennessee and Marcelo Sant'Anna LBNL working with the electron-TOF setup at beamline 8.0.


Former Team Member Ivan Dominguez taking data at beamline 8.0.


Summer 1999 REU student Tara Goddard learned the mechanics of taking data.


Graduate Student Lan Dang is collecting data at the ALS.

Arnaldo Naves de Brito (LNLS, Brasil) is working on our magnetic mass analyzer.


Team member Jim Cotter from Reno, NV is working hard to finish his PhD.


Team member (co-PI (DOE EPSCoR)) Paul Neill (right) from Reno, NV and K.Tong Leung a collaborator from Waterloo, Canada with the ion-TOF system of the XAMS endstation. The experiment is setup at beamline 9.3.1 at the ALS and in full operation for ion-ion and electron-ion coincidence measurements.


Carmen Cisneros (UNAM Cuernavaca, Mexico) and Fred Schlachter (ALS) at the ALS in Feb. 1999

Brad Armen a former post-doc from the University of Tennessee with the ion-TOF system of J.C. Levin. The experiment is set up at beamline 6.3.2 at the ALS for precision measurements of the ratios of double to single charged ions.


Marc Simon (middle) a collaborator from Paris, France helps with the setup for ion-ion coincidence measurements with the ion-TOF chamber on beamline 9.3.1 at the ALS. Yasushi Uehara (standing) a collaborator from Mitsubishi Electronic Corp., Japan was on a 1-year sabbatical leave to work with our team at the ALS. David Hansen, a former team member responsible for the ion-TOF setup is listening.
