some detail, together with a brief comparison of the measured energy output with the theoretical predictions of the
’surface current’ model of the SP radiation.
Turn-by-turn Data Acquisition and Post-processing for the Diamond Booster and Storage
Ring
The Diamond booster and storage ring are
equipped with Libera Electron Beam Position
Processors with turn-by-turn capabilities.
We describe here the turn-by-turn data

acquisition system and the software used for post-processing the beam data. The signals from the Libera boxes are
acquired and controlled with EPICS and then transferred to the MATLAB environment via the MATLAB Channel
Access. Here they are post-processed using MATLAB capabilities and dedicated software linked to MATLAB. Examples
of data acquired and measurements performed during Diamond booster and storage ring commissioning are
reported.
First Use of Current and Charge Measurement Systems in the Commissioning of Diamond
This paper will discuss the results obtained
from the charge and current measurement A.F.D. Morgan, M.G. Abbott, G. Rehm (Diamond)
systems installed in Diamond during the
commissioning stage of operation. The charge measurements are gathered from integrating current transformers
and Faraday cups, while the current is measured using a DC current transformer in each ring. The measured beam
parameters will be investigated, as well as how well the devices performed against expectations.
Performance of Global Diagnostics Systems during the Commissioning of Diamond
This paper summarises data acquired with
beam diagnostics systems distributed glob- G. Rehm, M.G. Abbott (Diamond)
ally through Diamond’s Linac, transfer
paths, booster and storage ring. It shows results from the electron beam position monitors using their capabilities
to monitor transient events, the booster ramp as well as stored beam. The performance derived from real beam
measurements is compared to measurements obtained in the lab using signal and pulse generators. Other systems
of widespread use are screens and synchrotron light monitors. Their performance and control system integration
based on IEEE1394 camera technology is presented. Finally, first results from the fast and slow beam loss monitoring
systems are described.
Diamond Optical Diagnostics: First Measurements of Six-dimensional Phase-space
We present in this paper a first set of measurements
of the six-dimensional phase- C.A. Thomas, G. Rehm (Diamond)

storage ring. We recall the predicted performance and compare it with our first measurements. The two pinhole
