General rule: Only samples and equipment specified in approved proposals and validated by the ALBA Health and Safety Office may be used on BL11-NCD-SWEET.

Please contact the beamline staff for support and inquiries.

What is can be limited at the BL for technical reasons:

• Nanoparticles: Sub-micron powders are accepted only if securely confined, fixed to a substrate, or embedded in a matrix; handling of loose nanopowders on the beamline or lab is not allowed.
• Laser: class III and class IV without proven experience/training and protection.
• Toxic/corrosive gas: Usage of gases considered as toxic and/or corrosive (e.g. NH₃, SO₂, CO, Cl₂, HCl) is not allowed at this beamline.
• Equipment(s) producing electrical fields without shielding.
• Equipment(s) producing magnetic fields without shielding.

What cannot be done at the BL for safety reasons:

• Not allowed BSL higher than 1.
• Radioactive compounds: Radioactive sources as defined in RD1217/2024 will not be accepted. Samples containing radioactive isotopes below these specific limits MUST be declared and acceptance will be studied case by case.
• Illegal substances and/or samples: (f.i. drugs, unregulated agricultural or food samples, etc.) unless it is explicitly proved that it is allowed by Spanish regulations.

What can have a restriction:

• Heavy and bulky samples or sample environments. Please contact the beamline staff

Disclaimer: This list is not comprehensive; it only indicates the experimental conditions and sample characteristics that could not be accepted due to technical and/or safety reasons. The acceptance of any materials (including equipment) is subjected to the availability of all required safety conditions and protective equipment.
