  COLTRIMS  SPECTROMETER SYSTEMS
 
 
 
The Cold Target Recoil Ion Momentum Spectrometer was developed for the spectroscopy of atomic and molecular reactions. Several atomic physics groups contributed to the technique and nowadays so-called Reaction Microscopes provide the most detailed insight in the dynamics of objects on atomic scales, like atoms, molecules and clusters.

The technique involves a supersonic gas jet target, a well-defined electrostatic field and position&time-sensitive particle detectors, e.g. of the RoentDek types DLD and HEX.

RoentDek builds custom-designed COLTRIMS systems ranging from complete setups to individual and modular spectrometer solutions. Complete systems were designed for:
 
 
    IKF, Frankfurt, Germany
    CAB, Bariloche, Argentina
    PUC, Rio de Janeiro, Brasil
    Auburn University AL, USA
    TAGEN, Sendai, Japan
    ANL, Argonne IL, USA
    HU, Zarqa, Jordan
    AIST, Tsukuba, Japan
    NRC, Ottawa, Canada
    LBL, Berkeley CA, USA
    JR MacDonald Lab, Manhattan KS, USA
    University of Rochester NY, USA
    Peking University, Beijing, China
    East China Normal University, Shanghai, China
    Griffith University Brisbane, Australia (in construction)
    Tokyo University (Kashiwa), Japan (in construction)
COLTRIMS setup components (gas jet target parts, spectrometer, detectors) have been delivered to:

    ETH, Zürich, Switzerland
    JILA, Boulder CO, USA
    SIOM, Chinese Academy of Sciences, Shanghai, China
    Banaras Hindu University, Varanasi, India

  The majority of these groups is in an ongoing collaboration with RoentDek and/or the IKF atomic physics group in Frankfurt/Germany. Each COLTRIMS setup consists of a modular assembly which can be adapted to our customer’s demands and requirements.

Worldwide, RoentDek detectors and electronics are used in spectrometers and imaging systems similar to the COLTRIMS-system. More information can be found at www.roentdek.com
