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 *** 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.

Under a continuous-beam mode,the isotopes of interestwere implanted into DSSD1 of 142μm thickness,DSSD2 of 40μm thickness,and DSSD3 of 304μm thickness in a certain proportion,where the subsequent decays were measured and correlated to the preceding implantations by using the position and time information the higherstatistics data onthe well-known protons and γ rays from those beam contaminants decays were also collected,which can be usedas good calibration references to validate and to optimizethe analysis program in obtaining accurate informationfrom-decay spectroscopy.
