8 Single-Event Transients (SET)

SETs are defined as heavy-ion induced transients on VOUT, PG, or SS of the TPS7H1121-SEP.

The species used for SEL testing were Silver (109Ag at 15 MeV/nucleon and 19.5 MeV/nucleon at TAMU and KSEE, respectively). For both ions an incident angle of 0° was used to achieve an LETEFF = 48MeV·cm2/mg (for more details refer to Table 5-1). The kinetic energy in the vacuum for 109Ag is 1.633 GeV and 2.123 GeV for TAMU and KSEE, respectively. A flux of 1.02 × 105 to 1.31 × 104 ions/cm2/s and fluence of 107 ions/cm2 per run were used for the SET characterization discussed in this chapter. Over the course of testing three devices, not a single transient or SEFI was recorded on any of the monitored signals indicating that the TPS7H1121-SEP is SET/SEFI free up to LETEFF = 48 MeV·cm2/mg.

Waveform size, sample rate, trigger type, value, and signal for all scopes used is presented on Table 8-1.
