We finally managed to get the striplines and target support rails aligned to the axis of the horn after discovering some inaccuracies in the horn box mounting surfaces. The final ceramics for the target support won't be done until September, so we had some G-10 substitutes made for testing. The first insertion of the target was done without surveying the position of the target. It was close enough that it was able to insert completely without scraping the inside of the inner conductor. The final pictures show an overview of what MI-8 looked like as of 6-20-01.

Bench assembly of the target module

The air plumbing wasn't ready yet, so we just attached the target to its structural supports.

Muscling the target module into the horn box

The pillow blocks on the bottom of the target support carriage engage surprisingly easily with the Thomson rails on the horn box. The surprise comes from the fact that we won't have the target module assembly stand ready for another month and a half, yet we were able to assemble and align the pillow blocks adequately without it.

Inserting the Aluminum Target for the first time

View looking upstream from the hole in the downstream end cap

It is plain to see that the target is low and off to beam left, but not enough to interfere with the horn.

Very soon we will be able to route power to the horn.
