Ta#54 HP-SIS target description:

Total Ta foils = 470 [6x20 packs + 350 single discs]

Foil Thickness = 0.025mm

Target density = 14.72 g/cm3

Target length = 3.4cm

Total Mass = 50.0372g [Incl foils + Ta wire on 6 packs]

 While removing the SiC#42 it became apparent that the multipin guide pin had become loose again and was not allowing the target to dismount from the module.

The multipin shoulder bolts were removed and then the multipin was able to be pried off.

However the NHC manipulator were not able to reach the guide pin to remove it, which would be required before the SiC#43 could be installed.

The target module was then moved to the SHC where the guide pin could be removed and the installation of SiC#43 took place, along with the transfer of the parasitic attachment onto the SiC#43.

This problem seems to suggest that the multipin could use some redesign to ensure smoother target exchanges.
