An RF dipole, serving to split particle bunches into two equal parts. The box in the front is the power amplifier. The actual dipole is the horizontal cylinder in the background.

An accelerating radio frequency cavity, part of the 10MHz system. The red top contains the tunable ferrite-loaded cavity, and the blue bottom holds the power amplifier.

Beam Gas Ionisation (BGI) monitor. This device measures the horizontal profile of the beam.

A sensitive position pick-up. This pick-up has very large electrodes, and pre-amplifiers are mounted directly on the PU. Two of the amplifiers, which use tubes for radiation resistance, can be seen.

An electron cloud diagnostic pick-up. Some types of beam can create lots of free electrons, sometimes enough to destroy the beam itself.

At the left, between the pole pieces of the bending magnet, a pick-up of the orbit measurement system (CODD).
On the blue table a wire scanner, measuring the vertical profile of the beam by sweeping a wire through its path while detecting scattered particles.

At the left, between the pole pieces of the bending magnet, one of the pick-ups of the orbit measurement system (CODD). On the blue table, from left to right, a quadrupole doublet and quadrupole magnet PR.QSE87 used for tuning the machine Q.

Radio frequency cavity 'Barbara' This 80.11MHz cavity serves to shorten the particle bunches to the 4ns required by the LHC, prior to ejection to the SPS.

Radio frequency cavity 'Lydia': This 80.11MHz cavity serves to shorten the particle bunches to the 4ns required by the LHC, prior to ejection to the SPS.
