摘要：

The AMS-02 detector has a strong magnetic fringing field where the Time Of Flight PhotoMultiplier Tubes (PMTs) are installed. Each Time Of Flight (TOF) counter has 2 or 3 PMTs per side for redundancy, but the limits on AMS-02 total weigth and power budget imposed severe constraints on the HV channels number. Each HV channel is connected to two PMTs and, due to the different performances of each PMT, which depend critically on the PMT position in the TOF, two meta-heuristic algorithms were used to optimize the TOF performances. This paper describes the results obtained with a combination of simulated annealing and genetic algorithms.
