Pre-assembly test of 3 HF wedges at a time

To check the geometry of the individual HF wedges a special jig has been developed which allows mounting 3 HF wedges at a time. The jig simulates the exact geometry of the final shield where 9 wedges will be assembled forming the 'D' shaped half HF. Such pre-mounting has allowed to verify the accuracy of the construction of the individual wedges and made sure that the final assembly will not meet any structural problem.
