The transfer line from the CERN proton synchrotron
(PS) to the super proton synchrotron (SPS) requires a new
beam position measurement system in view of the LHC.
In this line, the single passage of various beam types
(up to 7), induces signals with a global signal dynamics of
more than 100 dB and with a wide frequency spectral
distribution.
Logarithmic amplifiers, have been chosen as technical
solution for the challenges described above.
The paper describes the details of the adopted solutions
to make beam position measurements, with a resolution
down to few 10-4 of the full pickup aperture over more
than 50 dB of the total signal dynamics.
The reported performances has been measured on the
series production cards, already installed into the machine
and on one pickup in the transfer line.

The hardware used in the SPS Experimental Areas to control the beam
instrumentation electronics and mechanics of the particle detectors is
based on CAMAC and NIM modules. The maintenance of this hardware now
presents very serious problems. The modules used to operate the
Experimental Areas are numerous and older than 20 years so many of them
cannot be repaired any more and CAMAC is no longer well supported by
industry. The fast evolution of technology and a better understanding of
the detectors allow a new equipment-oriented approach, which is more
favourable for maintenance purposes and presents fewer data handling
problems. VME and IP Modules were selected as standard components to
implement the new electronics to control and read out the particle
detectors. The first application implemented in this way concerns the
instrumentation for the Scintillation Counters (formerly referred to as
triggers). The fundamental options and the design features will be
presented.
