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 ancllary triggers, which are used to monitr/study detector performance run in parallel to the main production triggers. These 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.
Random	The random trigger can be enabled from the PS css screen.

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

Trigger Type	Trigger Bit (starting from 1)	Typical rate
FCAL LED	3	> 10 Hz
BCAL LED	9 or/and 10	> 1 Hz
Random	12	50 Hz

The bit assignment and typical rates of the TS FP triggers is
