The ALBA Booster synchrotron is designed to ramp an electron beam of up to 4 mA from 100 MeV to 3 GeV in a 3 Hz cycle. The Booster is equipped with two common λ/4 striplines for tune excitation and precise beam position measurement. Beam excitation along the cycle requires the amplitude kick to increase synchronously with the energy ramp. This paper shows the excitation and measurement system at ALBA, including both mechanical and hardware instrumentation as well as control system functionalities.

The ALBA Booster is a synchrotron designed to accelerate electron beam from 100 MeV to 3 GeV in a 3 Hz cycle. The maximum pulse coming from the ALBA Linac provides 4 mA in the Booster. In order to check all the Booster sub-systems, a Booster pre-commissioning took place during two weeks between December 2009 and January 2010. This paper presents the Diagnostics elements installed in the ALBA Booster and our experience during the Booster pre-commissioning.

Beam position monitors (BPM) characterization has been widely studied at ALBA Synchrotron Light Source. Special care has been taken on the analysis of their electrical offset in order to achieve submicron beam stabilities. This paper shows the results of the BPMs offset study for Booster and Storage Ring. The electrical effect of the different vacuum vessels housings the BPMs is also reported.
