Comparison of the FOM for three scintillators using single-ended and double-ended readout.
| LSO | LaBr3 : Ce | Ultra-fast | |
|---|---|---|---|
| Full energy detection efficiency | 0.6a | 0.4a | 0.5b |
| Total number of photoelectrons Npe | 4000 | 7400 | 4000b |
| Single-ended surface B CRT WSB (ns fwhm) | 0.16 | 0.14 | 0.070b |
| Single-ended surface B figure of merit (FOM)1 | 14.6 | 7.4 | 23b |
| Double-ended CRT WWAB (ns fwhm) | 0.111 | 0.072 | 0.020b |
| Double-ended figure of merit (FOM)2 | 21.0 | 14.4 | 81b |
