A MiniRotator on test: bent downwards (using the remotely controlled jacks) to select a certain helicity.

A MiniRotator on test: bent upwards (using the remotely controlled jacks) to select the opposite helicity.

A bellows unit allowing flexible connection between sections of beam pipe in adjacent magnets. Note the metal fingers which slide in complementary holes
to maintain the circuit for mirror currents.
