Level-1 Trigger Shift

Configuration for Production Runs

Production data is taken with the following configuration, which has to be selected at the RCM Run Config GUI:

RUN:	EXPERT
SETUP:	hd_all.tsg
CONFIG:	FCAL_BCAL_PS_m9.conf (main production mode) or
	FCAL_BCAL_PS_m10.conf (debug mode, readout raw samples for FADCs 250 and 125)

Trigger Types

1. GTP Triggers

Currently, there are following main (GTP) triggers used in data production:

Trigger Type	Trigger Bit (starting from 1)
FCAL + 0.5 BCAL > 0.5 GeV	1
BCAL > 1.1 GeV	3
PS	4

Trigger bits used in spring 2016 are listed in

2. TS Front Pannel Triggers

Several ancillary triggers run in parallel to the main production triggers. These triggers are distributed through the TS front pannel, and are used to monitor/study detector performance. The triggers are listed below:

FCAL LED	The pulser can be enabled using the FCAL css screen. FCAL team can also run an LED pulser script.
BCAL LED	The pulser can be enabled using BCAL css screen. Usually the pulser script is enabled, which alternate upstream and downstream LEDs for various BCAL collumns.
Random	The random trigger can be enabled from the PS css screen.

Assignment of the TS FP trigger bits and typical trigger rates are shown in the table:

Trigger Type	Trigger Bit (starting from 1)	Typical rate
FCAL LED	3	> 10 Hz
BCAL LED	9, 10 (single or both bits can be seen, depending on the bcal LED script)	> 1 Hz
Random	12	50 Hz
