Conclusions
IEFC
The TDC2/TCC2 consolidation activities are successfully completed, within schedule, budget and with no major problem.
The corrective and preventive maintenance recently implemented will reduce corrosion of the vacuum equipment and reduce machine downtime in the future operation of the beam lines.
Individual dose management has been challenging for some groups.
