SESAME
ID11-HESEB

The HESEB beamline was designed to cover the range of photon energies from about 70 eV to 1800 eV. An Apple II type Undulator is used as the photon source, and a Plane Grating Monochromator (PGM) is used as the photon dispersing tool. In addition, HESEB beamline contains a beam splitter unit placed just after the PGM that enables to build of a second branch that can work in the same photon range interchangeably as the ID11-right branch. The HESEB analysis chamber allows fluorescence and total electron yield measurements. A motorized sample manipulator is at disposal for raster measurements and allows heating and cooling of the sample, as well as giving the possibility to impose a magnetic field.

Endstations or Setup

HESEB End Station

Description
HESEB Analyze chamber has a special entrance that gives the option to install an elliptical focusing capillary that can focus the beam down to 20x20 ┬Ám2. In addition to capillary, the pumping unit and gate valve with a particular window between the beamline and analyzes chamber allow analysis at low vacuum, under He atmosphere. With the help of that design, cultural heritage samples, sensitive to high vacuum can be analyzed in the HESEB
