|
Endstation identifier |
Ion-beam endstation (available fall 1998) |
|
Scientific applications |
Photoionization of ions |
|
Characteristics |
The charged ion beam from the ion accelerator is merged with the photon beam (counter propagating) for approximately 0.5 m. An analyzing magnet disperses the ion beam based on charge state following the interaction region. |
|
Spot size at sample |
1.5 mm (h) x 1.5 mm (v) |
|
Samples |
Beam of positively charged ions |
|
Sample environment |
Differential pumping permits gas pressures of up to 10-5 Torr |

Endstation identifier |
High-resolution gas-phase electron spectrometer |
|
Scientific applications |
High-resolution atomic and molecular electron spectroscopy |
|
Characteristics |
The electron spectrometer uses a gas cell on the beam axis to form the interaction region between the sample and the photon beam. The analyzer rotates from 0° to 90° relative to the polarization vector of the photon beam, permitting angle-resolved measurements. |
