SESAME
ID10-BEATS
BEAmline for Tomography at SESAME
SESAME's beamline for hard X-ray full-field microtomography. BEATS is optimized for absorption and phase contrast radiography and tomography with hard X-rays. The beamline layout is inspired by TOMCAT, the tomography beamline of the Swiss Light Source (SLS).
BEATS was designed, procured, constructed and commissioned by Europe Horizon 2020 as a collaboration between research facilities in the Middle East (SESAME and the Cyprus Institute), and European synchrotron radiation facilities ALBA-CELLS (Spain), DESY (Germany), the ESRF (France), Elettra (Italy), INFN (Italy), PSI (Switzerland) and SOLARIS (Poland). The project was launched on 1st January 2019 and ended in June 2023 with the official inauguration of the beamline.

Sample
Other Sample Type
Max. load: 20 kg. The best sample shape for tomography is a cylinder. Prepare your sample as close to this form as practical. Strongly absorbing materials should be made smaller or thinner to ensure good transmission and high-quality reconstructions.
Mounting Type
Samples can be mounted with wax, glue, tape or inside plastic vials and containers on magnetic sample holders.
Techniques usage
Imaging / X-ray tomography
Max rotation speed 90 rpm.
Manipulator or Sample stage
Description
The endstation has a max. payload of 25 kg.
The endstation is composed of 5 motorized axes:
- Large range granite X-axis (horizontal)
- Large range granite Z-axis (vertical)
- Air bearing tomographic rotation stage + feedthrough
- X-Y micropositioners for sample alignment
