6. TPC commissioning: DAQ, ECS
Calibration runs
Meeting about TPC/TRD FERO Control 31-Jan-06
The TPC requires several different types of calibration runs:
Pedestal taking
Pulser calibration
Laser calibration
Krypton calibration
All the above calibration procedures must be
Defined: sequence of operations
Implemented: 1 (set of) program(s) for each operation
Included in the DCA: procedure steering the execution of the operations. Implemented as a FSM coded in SMI.

7. An example: pedestal calculation
Consists of the following operations:
Set FEE to ‘pedestal mode’
Done using the DCS
Data taking (DAQ+LTU)
Recording on local LDC disk
No event building
Compute pedestal on every LDC
Pedestal can be stored immediately or later in database to be loaded via DDL or DCS
Set FEE to ‘normal mode’
The implementation of a pedestal run requires work in the TPC-DCS

10. Next steps for calibrations
Name of a person responsible for TPC calibrations
This person defines every calibration procedure:
Sequence of operations
Building blocks (programs, who provides them)
The ECS team implements the logic to steer the calibration procedure (commands sent to DCS, DAQ, LTU)
The building blocks are provided by the TPC team
Tests and debugging
