As shown in Fig.1,the decay-time spectrum was generated by the summation of the time differences between an implantation event of 27P and all the subsequent decay events which occur in the same x-y pixel of the same DSSD.To reduce the probability for event misidentifications were not allowed for multiple-pixels recorded decay events such as particles traveling along the detector through several pixels,or the rare events in which the ions were implanted very near the gap betweens trips,allowing the emitted protons to travel through two pixels.
