EUROBALL

HIGH VOLTAGE

---

INTRODUCTION

The EUROBALL gamma-ray spectrometer is installed at the Institut de Recherches Subatomiques, Strasbourg in France. A set of Euroball technical documents is provided by the Nuclear Physics Support Group at Daresbury.

High Voltage hardware is supplied by LeCroy and C.A.E.N. Control and user interface software was developed by the University of Liverpool Nuclear Physics Group.
