ALICE Trigger Status
This document details the status and integration progress of the ALICE Trigger system following the DCS workshop held in Birmingham on October 10, 2006. It covers the setup and configuration of the CTP, its integration with ECS and DAQ systems, and monitoring advancements. Key achievements include the installation of two setups in Birmingham, software readiness for CTP configuration, and the development of a monitoring server. Future tasks include configuring the boot/disk server and the establishment of a graphical user interface for partition configurations.

Content • Status • Integration with ECS and DAQ • Interface to DCS ALICE Trigger Status
Final CTP setup CTP LTU (LVDS) BC clock (coax. Cable) LTU - FE (LVDS) RoI connections ALICE Trigger Status
Status • 2 setups installed in Birmingham • 2 setups installed in CERN lab, 1 is connected to DAQ/ECS reference setup • Set of boards for 5th setup available • Software for CTP configuration/testing ready • CTP proxy code for integration with ECS ready • CTP DIM server is being developed, ‘CTP counters monitoring’ part ready ALICE Trigger Status
CTP-ECS-DAQ integration • - Started in July 2006 • - CTP installed in Birmingham lab at CERN • and connected to DAQ lab (60 m) • DAQ emulates two detectors (DDG) • DAQ receives CTP Readout and Interaction Record via DDL • Front-end Emulator (DDG) receives via TTC L0/L1 triggers and L1 /L2 messages, generates the event data and generates BUSY signals • Under ECS control CTP provides correct Start and End of the run sequences (SOD,EOD) • ECS/CTP/DAQ are tested to configure and run any partition out of two detectors ALICE Trigger Status
CTP – DCS interface • All voltages are read out through I2C link which can be connected to: • CTP INT board VME bus CTP DIM server • PC equipped with I2C interface DIM server –tested on each board with I2C-parallel port adapter connected to PC with Windows/XP ALICE Trigger Status
DCS usage - DCS network - monitoring - control • DCS network connects together 12 computers : • linux boot/disk server • 8 diskless VME computers controlling 8 VME crates • PVSS project node • Operator node ALICE Trigger Status
Monitoring • ~ 1000 integer values, ~per several minutes, • accesible through DIM servers running • on CTP VME computers • counters: 727 + 24*12 = 1015 • voltages: (11+24)*4 = 140 • temperatures: 11+24 =35 More levels of warnings and alarm required in case the values go out of given range ALICE Trigger Status
Control • automatic powering off the crate in case of high temperature, subject to actions associated with alarms • remote SYSRESET VME signal for each crate – has it been tested already ? ALICE Trigger Status
Summary • CTP hardware ready for installation in the pit • Integration with DAQ/ECS going well • Still to be done: • boot/disk server configuration • the usage of ECS/DAQ database • GUI for preparing partition configurations • DIM servers accessing CTP services • PVSS project ALICE Trigger Status
