Taikan Suehara, CALICE electronics and DAQ WS, 16 Dec. 2014 page 2 All CALICE Tech. proto. are based on the same chip family – ROC chips by Omega There existed a common DAQ elec. by UK Needs for common DAQ –Minimal effort in total –Common TB (towards real experiment) –Hybrid (Si + Sc) Groups are rival as well as collaborators –Need ‘neutral’ common system – difficult –Kyushu is at good position for neutralness Combined DAQ: overview

Taikan Suehara, CALICE electronics and DAQ WS, 16 Dec. 2014 page 10 Talk to Labview is not efficient –Maybe better to directly talk to LDA BUSY treatment –Si busy cannot be used now –Common CCC is better to treat busy CCC specification should be common Online monitoring / quality check More layers of silicon Well-defined LCIO structure Combined DAQ: ToDo

12. Taikan Suehara, CALICE electronics and DAQ WS, 16 Dec. 2014 page 12 The first trial is successful, but many adhocs –Independent CCC –No busy synchronization Task force for CALICE-wide DAQ formed –Silicon: Remi, Frederic, TS (coordinator) –Scintillator: Mathias, Jiri –SDHCAL: Laurent Next TB: Si+SDHCAL next year (probably) Next step: CALICE DAQ TF

13. Taikan Suehara, CALICE electronics and DAQ WS, 16 Dec. 2014 page 13 The goal of to deliver the proof that the following combinations of running are possible, SiW-Ecal/SDHCAL, SiW-Ecal/AHCAL (or equivalently SiW-Ecal/ScW-Ecal), ScW-Ecal/AHCAL. DAQ task Force is to work out a set of technical questions (hardware and software) and propose and enact concrete means to answer these questions, based on the hardware that is currently available. It is asked to the group to report regularly at the Technical Board and provide a documentation summarising the solutions after one year. In the second year, the task consist in the critical expertise of the running setups of the combined tests. Task Force: Mandate

High level DAQ software (EUDAQ?) –Run control, event building, run number, monitoring,… Common data format (LCIO class) Partial or optional sharing of firmware and software etc. Things to be considered

16. Taikan Suehara, CALICE electronics and DAQ WS, 16 Dec. 2014 page 16 After the first meeting, my impression is that reaching to the agreement about things shown in the previous slide is not easy.  we need some time to get consensus We will firstly get informed more about each system, by reporting about each system from each expert. Monthly regular meeting with flexibility to change the frequency. How to Proceed

17. Taikan Suehara, CALICE electronics and DAQ WS, 16 Dec. 2014 page 17 Effort to re-integrate CALICE DAQ is critical towards combined TB and real ILC detector. First trial of Si+Sc combination was successful though some issues remained. We shall move to more generic CALICE DAQ with an experts’ Task Force. Any inputs/opinions from experts/non- experts are highly welcome.Summary
