The Endstations

A schematic description of the endstations and techniques/instrumentation currently available on the beamline BACH can be found here.

In the UHV endstation of the BRANCH A it is possible to perform a multi-spectroscopy investigation with photoemission (including ARPES), x-ray absorption (TEY,PEY,TFY,PFY), x-ray emission and x-ray magnetic circular dichroism in remanence.   A LEED and several electron beam evaporators are available to deposit  selected metals on the sample surface at different temperatures (50 K-750 K).

The experimental setup of the BRANCH A can also combine Laser and Synchrotron Radiation (SR) in order to study the dynamics of the photo-induced excited states of electronic and magnetic systems with pump-probe time-resolved x-ray absorption spectroscopy. Elettra Synchrotron radiation source provide radiation pulse widths sufficiently short to investigate dynamic processes in the time between 70 ps up to 0.5 μs. Typically, optical excitation of the sample is done by laser pulses (synchronized to either hybrid or multi bunch SR pulses), and probing is performed by time-delayed synchrotron radiation pulses. Time resolved XAS setup is OPEN TO USERS!

 A SAMPLE-PREPARATION UHV chamber, directly connected to the Endstation A can be used to grow thin films of metals or metal oxides and deposit organic/inorganic molecules, hybrid systems or magnetic elements on solid surfaces.
A fast entry chamber for surface preparations (gas dosing up to 100 mbar and annealing) is also connected to the preparation chamber.
The fast entry can be connected to a UHV vacuum suitcase.

The experimental setup of the BRANCH B hosts a new endstation dedicated to x-ray magnetic circular dichroism in high magnetic fields (± 6.5 Tesla) along the beam and variable tempertaure from 1.9 K to 340 K on the sample in a base pressure of 4x10-11 mbar.  A surface preparation chamber will be available soon for the investigations of the magnetic propertis of in situ grown samples. This endstation is NOT OPEN TO USERS
The branch B now hosts a second endstation with a set-up for pump-probe time resolved soft x-ray absorption spectroscopy with  movable MCP is currently hosted for a long-term project.

The BRANCH C hosts an in-operando setup for XAS characterization of liquid/solid interfaces, cyclic voltammetry and elctrodeposition.

The beamline is also available for the installation of user endstations for long term projects.
