Schematic of ECLTRG database part • When each run starts, some of currently applied parameters on hardware such as firmware version(8), fam energy threshold(624) and timing offset(624) are automatically saved on local machine, converted to appropriate format and downloaded to Belle II main database server. • Other parameters such as pedestal(624) and fitter-CC(303264) will be added. • Comparing parameters on A, B and C will be added. If all 3 have same value, return 1. Otherwise, 0. This output will be added ECLTRG ready signal.

During trigger and DAQ operation upon beam collision, it is important that Belle II detector status have to be monitored in a process of data- taking against an unexpected situation. Slow control system, built in the Control System Studio (CSS) which is a GUI window design tool based on Eclipse, is one of monitoring systems in Belle II operation. Database and archiver servers are connected to slow control system. Experimental parameters are downloaded to Belle II main database server which is based on PostgreSQL. Real-time results are stored in archiver server which is based on EPICS(The Experimental Physics and Industrial Control System) archiver appliances and tomcat which is open-source java servlet container. In this study, we report the development of slow control system for the Belle II electromagnetic calorimeter (ECL) trigger system. Abstract Slow Control System of ECL Trigger  Updating period is several seconds, and this is why the name of the system has “slow”.  Accessing to ECLTRG module and archiving outputs from it takes some time(~10 -1 second) depending on number of them.  Control, monitor and store data.  Recognize/handle a simple problem and report a significant one.

Conclusion TRGCTR OPI • Ready signals and initialization commands of not only ECLTRG but also all sub-trigger should be prepared. Currently, only ECLTRG provides such functions. 1. User module Part  GUI monitoring module  ECL Trigger library included ECLTRG OPI • ECLTRG system consists of FAM, TMM and ETM. This user module shows status of each sub-system such as version and readiness. 3. Database Part  Database using “PostgreSQL” package.  Upload/download parameter from local server to Belle II main database server. Configuration DB ECLTRG TMM temperature • Temperature measured by sensor near and far from TMM FPGA. • TMM temperature data from archiving server are extracted and plotted. • FAM temperature is also prepared as same style as TMM. • From above plots, shapes of ECLTRG detector luminosity and SUPERKEKB providing luminosity are consistent. • ECLTRG SLC is not only for monitoring ECLTRG status, but also for SUPERKEKB machine tuning and Beam BKG study. For such studies, rate of ECLTRG each trigger bit information would be helpful. • Currently, accelerator luminosity and error of it(2), detector luminosity(1), integrated luminosity(1), averaged hit-rate(4), FAM temperatures(52x2) and TMM temperatures(7x2) are archived. • Other PVs such as noise(624) and rate of each trigger bit(624) will be also archived.
