Service to the user The user have a 2-channel arbitrary delay generator system Stanford DG535m
remotely controlled in BTF control room with the respecive bypass in BTF Hall. User customizable trigger signal (source LINAC SYS) STANFORD Delay Generator DDG535m

BTF Setup Menu (BSM)
→ Go Forever = lets the DAFNE injection rejected pulses (till the Odoscope one) to be delivered at set frequency to BTF
→ Single Shot = only one pulse delivered to BTF, after the DAFNE injection pulses

General Timing Status (GTS)
→ Normal = cutoff trigger signal @ BTF (the DHPTB101 still works!!!)
→ BTF = gives trigger signal @ BTF and implements BTF status setup (BSM)
→ BTF one shot = gives trigger signal @ BTF and implements BTF status setup for one shot per second or manual shot

ODOSCOPE setup (ODO)
→ DAFNE = cutoff the DHPTB101
→ DAFNE+BTF = permits DHPTB101 to pulse

DAFNE+BTF status

MANUAL SHOT
GTS → BTF 1 shot
BSM → Single shot
ODO → DAFNE + BTF
Press RUN BTF button and it fires one pulse

One shot per second
GTS → BTF 1 shot
BSM → Go Forever and number of impulses = 1
ODO → DAFNE + BTF
Press RUN BTF button and it fires at 1 Hz (two pulses per second in DAFNE injection)

Maximun shot rate
GTS → BTF
BSM → Go forever and number of impluses = 49
ODO → DAFNE + BTF

Q4 signal || BTF word signal ⇒ Syncro word (~8usec before gun pulse)

  Cable panel n.11(inside) SlowControl rack's hall in the BTF Control Room -> output from trg board send to 11(inside)-1

BTFTG1(user) signal ⇒ Delayed signal (~8usec as before + 6usec delivering time + user delta time) to match the bunch arrival time in btf hall

  Cable panel n.11 in BTF Control Room (near BTF Hall concrete wall) -> output from 11-1, delayed by Stanford C && !D, send to 11-3, from 11(inside)-3 send to a cable TG1BTF in BTF Hall

BTFTG2(user) signal ⇒ Delayed signal (~8usec as before + 6usec delivering time + user delta time) to match the bunch arrival time in btf hall

  Cable panel n.11 in BTF Control Room (near BTF Hall concrete wall) -> output from 11-1, delayed by Stanford A && !B, send to 11-2, from 11(inside)-2 send to a cable TG2BTF in BTF Hall

BTFTG0 A/B(btf staff) signal ⇒ output from trg board, delayed by Stanford C && !D, send to a cable TG0BTF in BTF Hall BTFTG0 C/D(btf staff) signal ⇒ output from trg board, delayed by Stanford C && !D, send to a cable TG0BTF in BTF Hall

There are additional triggers available for the users:

BTF && LINAC state
it is possible to select an electron/positron only TTL trigger signal (see the purple signal on the scope screen). This trigger starts 60 ns after the LINAC trigger.

BTF && Calorimeter
it generates a TTL trigger signal only if there is a LINAC trigger AND a signal in the calorimeter (see the purple signal on the scope screen). This Trigger starts 450 ns after the LINAC trigger.
