摘要
The status of the OPAL Phase III microvertex detector is discussed briefly. This is followed by a more detailed description of the OPAL microvertex detector radiation monitoring and beam dump system. This system measures AC currents induced by radiation on each passing of the beams in silicon diodes mounted close to the microvertex detector front-end electronics. Examples are shown for incidents leading to a beam dump trigger. The integrated radiation dose is also discussed.
