SS80
PR.SS80 Layout database
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.

SS81
PR.SS81 Layout database
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.

SS82
PR.SS82 Layout database
Beam Gas Ionisation (BGI) monitor. This device measures the horizontal
profile of the beam.

SS83
PR.SS83 Layout database
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.

SS84
PR.SS84 Layout database
An electron cloud diagnostic pick-up. Some types of beam can create lots
of free electrons, sometimes enough to destroy the beam itself.

SS85
PR.SS85 Layout database
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.

SS86
PR.SS86 Layout database
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.
|
|
SS87
PR.SS87 Layout database
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.

PR.SS88 Layout database
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.

SS89
PR.SS89 Layout database
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.
