These photos were taken by Garth Huber before the experiment:

To the right: Gorgeous shot, looking upstream toward the scattering chamber. The HMS dipole is to the left, the beamline and SOS are on the right.

Closer view, looking upstream from beam left.

Looking downstream at the scattering chamber from beam left. To the left is the SOS while to the right is the beamline girder.

Looking from beneath, at right the beamline lies inside the HMS Q1 slot near 10.5 degrees.

Same region with camera closer to beamline level.

Looking from beneath, the beamline as it passes by HMS Q2 with only cm to spare.

SOS interaction with the downstream beampipe.

Closer view: SOS quad and beampipe.

SOS shield house and the beampipe.

HMS snout close to the scattering chamber minimizes the air gap.

When he thinks no one is looking, Dave Gaskell (aka "superboy") corrects the angle marks on the floor.

Entrance to the dump tunnel: where most of the beam goes after we're done using it.
