Modernisation of the 25-year-old electronics for RF signal acquisition and processing of the booster beam position monitor system is now in progress, with a complete design study for new electronics followed by the realisation of two fully operational prototypes. The specifications have been defined at the ESRF and the design work and production has been out-sourced to the same company that produces the beam position monitor electronics for the storage ring (Libera). The design reports have recently been approved and the prototypes are being tested by the manufacturer and are expected at the ESRF for further tests at the end of this year.
