METALJET D2+ SAFETY
Revision 19, November 2016 Page 2-2
Operating manual must be read and understood
This operating manual contains necessary information to ensure safe operation of the MetalJet D2+ source.
Each person involved in the installation, operation or maintenance must have read and understood this
operating manual.
Keep this manual handy and in a safe place for future reference. In case of this manual being lost or
damaged, please contact Excillum for a replacement copy (see Page ii for contact information).
In case the MetalJet D2+ source is moved to another location, make sure not to leave the manual behind.
2.1.4 X-ray radiation
In its original design the MetalJet D2+ source provides a high degree of protection from unnecessary radiation.
Therefore, do not modify, remove, or otherwise change any part of the MetalJet D2+ source unless this action
has been approved of by Excillum beforehand. However, no practical design can provide complete protection
nor prevent operators from exposing themselves or others to unnecessary radiation.
Personal radiation monitoring and protective devices are available. Operators are urged to use them to protect
against unnecessary radiation exposure.
X-ray radiation can be a health hazard
X-ray equipment may cause injury, or even death, if improperly used.
The MetalJet D2+ apparatus is a source of x-ray radiation, which is harmful to the human body. To avoid
health problems arising from exposure to x-rays, exercise the greatest possible caution when using this x-
ray source.
This x-ray source may be operated by, or under supervision of, authorized and trained personnel only.
All applicable local safety regulations must be strictly complied with.
2.1.5 Electricity and high voltage
Make sure electrical power is switched off, or other appropriate safety precautions are followed, before
maintenance or service work is performed.
The MetalJet D2+ source contains a high voltage generator. Proper high voltage precautions and grounding
techniques must be observed during installation and operation of the MetalJet D2+ apparatus.
The high-voltage decay time when power is shut down can be significant.
Read the document “AN-05 aka "No, you touch it". HVPS output fall and discharge times explained” from
Spellman which gives an estimation of the decay time http://www.spellmanhv.com/Technical-
Resources/Application-Notes/AN-05.aspx.
In no event should the safety interlocks on the MetalJet D2+ source be disconnected or bypassed.
