Dear Annalisa, 

Thank you for the table. 
As I understand you want to have: 
1. Electron trigger. 
PVCAL+ECAL minimum energy=300 MeV that corresponds 1.2 GeV electron momentum approximately. 
You don't want the limit on the maximum electron momentum. 
We expect 11 kHz trigger rate at I=20 nA (L=0.25*10^35) and Ebeam=6.4 GeV for this setting. 

2. FT trigger 
Your choice is 1.8-6.6 GeV energy deposition in the forward calorimeter FT. 
Expect about 4 kHz approximately at the same conditions (I=20 nA). 

Regards, 
Valery
