Commissioning of the Booster Synchrotron for the Diamond Light Source
The Diamond booster is a 158 m circumference,
5 Hz synchrotron which accelerates the
100 MeV electron beam from a linac to 3 GeV
for full-energy injection into the Diamond
storage ring. The booster has been commis-

sioned in the first few months of 2006, following successful initial 100 MeV trials at the very end of 2005. The injection
and ramping process, orbit correction and essential beam physics measurements are discussed as are extraction and
beam transport to the storage ring.
Beam Optic Measurements for the Booster Synchrotron of the Diamond Light Source
The booster synchrotron of the Diamond
Light Source is a full energy injector ramping
from 100 MeV to 3 GeV with a repetition
rate of 5 Hz. As part of the booster commis-

sioning, beam optic measurements were performed to characterize the booster performance. Through the use of the
beam position monitors, orbit corrections, tune and chromaticity measurements were performed at injection energy
and during the ramp. A first comparison with the booster model is also discussed.
Elettra Top-up Requirements and Design Status
Elettra is a 2.5 GeV third generation light
source in operation since 1993. To provide
more stable beams to the users, we plan to operate
in the so-called top-up injection mode.

The first step is the substitution of the present 1GeV linac by a 100 MeV pre-injector linac and a fast cycling 2.5 GeV
synchrotron booster foreseen to be in operation in 2007*. The present paper will report on the requirements for
the top-up operation in terms of radiation safety, diagnostics H/S, timing, modality, etc. and the design status. In
particular, a new BPM system, based on the log-ratio detectors, has been successfully commissioned on the present
transfer line and linac and is ready to be deployed on the new injector and to be used by the new foreseen shot to shot
transfer line booster to storage trajectory feedback system. Furthermore, in order to flatten the storage ring filling,
the top-up charge will be integrated where needed. Preliminary measurements on the bunch by bunch measurement
methods of the storage ring bunch charge are reported.

ELETTRA New Full Energy Injector High Level Software
The control system for the new full energy
injector* will be entirely based on Tango with C. Scafuri, F. Iazzourene (ELETTRA)
an object oriented distributed architecture.
The availability of the new and modern software platform led us to design and develop a new high level software
framework which allows a model-based accelerator control. The new design is fully object oriented and follows a
