for the AMS experiment

In this report the reliability of the control board (SMC) used in the TOF system for the AMS experiment is estimated and some considerations about the hard and soft failures are described. We mainly discuss the architecture board and the reliability features obtained.
During the failure rate evaluation we have always chosen the worst case to use a conservative approach.
We have evaluated an optimum value for the SMC short-term reliability,
however for long-life mission some redundancy must be introduced to increase
the hardware reliability.
