This thesis describes two separate areas of work conducted for the DELPHI detector at LEP.
The first concerns the Slow Controls of the DELPHI detector, which enable a single operator to oversee the proper functioning of the apparatus and to diagnose faults as they occur. The hardware and software of this system, as well as their interface to the experiment and the operator, are described. Some conclusions are drawn from seven years' design work and the initial six years' operation of DELPHI.
Secondly, a study is made of the production, at collision centre of mass energies close to the resonance, of mesons, decaying to . mesons produced via a B-hadron are used to measure the mean B lifetime,
