Camera commissioning
Commissioning undergoing in
the lab in UK at the moment.
Many small quick partial redesign and
addition to catch up with the fast changing
needs for commissioning diagnostic tools
A consistent part of the work involved in
testing and commissioning.
Keeping in mind this effort is prototyping
oriented. Towards ACTL soon…
