November 15, 2011 removed TaC#1 from TM1 and inspected TM1 for any obivous signs of trouble (Problems with EE at end of run).
Upon starting removal of the high current conductor fastener on A+ (Left oven leg) it became clear right away that the oven of the target was broken
as the leg moved as soon as the fasten was loosened. |

from the central block.Pictures were taken by Anders and Pierre.

Nb#6 has been inserted into the south hot cell in preparation for ionstallation onto TM1. During the pre-insertion inspection I noticed that I could
see the foil installed into the ionizer tube and that in did not seem to be seated or concentric to the tube itself. I had Anders and Friedhelm check this
and they deemed that it was ok. |

SiC#26 was removed from target module #4 this morning. Target shows the now standard arc marks on the 9 pin connector housing...pictures to follow.
Of greater concern is the amount of "plating out" or "arc" marks on both the insulators and connductor of the TM4 source tray.
