Technical and Safety reasons
As a general rule, experiments on BL11-NCD have to be performed exclusively with samples and equipments described in proposals (academic, in-house, proprietary) and validated by ALBA Health and Safety Office.
What cannot be done at the BL for technical reasons:
- Laser: class III and class IV
- 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 RD 35/2008 will not be accepted. Samples containing radioactive isotopes below these specific limits MUST be declared and acceptance will be studied case by case.
- Nanoparticles: Powder samples with sub-micron grain sizes are considered herein. Measurement on nano size materials could be authorized when sample is properly filled in sealed confinement, firmly bonded to a substrate or incorporated to a biological sample in such a way that nanoparticles are firmly bonded to it. However, the manipulation on the beamline and/or related laboratory of loose powder is forbidden.
- 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.
