Technical and Safety reasons

As a general rule, experiments on BL13-XALOC 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:

  • Equipment(s) producing electrical fields without shielding.
  • User's equipment using toxic or flammable products without the corresponding safety assessment and protection system.
  • Hazardous gases, because there is not a dedicated exhaust.

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.   
  • 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.
  • 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.

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.
