3. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 3 DBD LCFIPlus has been successful NIM paper will be submitted very soon (just after English improvement) LCFIPlus moves to the next step with expanded collaboration –Jan and Masakazu already joined –Anyone interested is highly welcome –We have a developer’s repository (git) as well as public repository in svnsrv.desy.de LCFIPlus expansion

4. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 4 Automatic creation of jprob/bcqprob (TS) Pair background (Jan) Jet clustering – overlay tagger FastJet inclusion? (Tomohiko) Vertex charge optimization (volunteers?) Better lepton ID / PID (Masakazu) pi0 tagging using w / wo conversion (Masakazu) More optimization on (volunteers?) –Fewer tracks (1+1 etc) –Vertices nearer to IP (current cutoff: 300  m) Other ideas (with manpower) very welcome! LCFIPlus Plans

7. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 7 Hybrid ECAL (Si + Sc) Reasonable robustness and cost Performance very similar to Si-only ECAL

8. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 8 Testbeam –To operate Si and Sc layers synchronously to analyze hybrid ECAL data Fluctuation of gain Cross calibration Timing resolution –Also possible to run ScHCAL (AHCAL) An exercise of “ILC DAQ” –Figure out what effort we need to combine various detector components Motivation of combined DAQ

9. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 9 ASIC level –Many technologies use “ROC”-family chips by OMEGA group – similar operation possible Interface level –UK group involved in CALICE DAQ – common DIF (detector interface), LDA (link data aggregator), CCC (clock control card) –UK stopped; we move from USB to Ethernet DAQ etc. in own way of each technology - compatibility starts to reduce Software – no common one, independent Three level of DAQ collaboration

10. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 10 SiW ECAL in ILD –Original DAQ for “testbenches” + Si modules –plain C + python, modular framework independent of any C++ or ilcsoft Scintillator ECAL/HCAL in ILD –LabView based on test DAQ for ROC chips –Plan to move to C++ and “XML DAQ” SDHCAL –xDAQ based (CMS DAQ system) More details on software

11. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 11 Minimum combination –Connect each DAQ at higher level (run control, event counting/building) –Use individual DAQ to talk to hardware Close connection –One central DAQ for everyone –Common interface to DIF/LDA –Less effort in total but need more communication How to Combine First step: minimum combination

12. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 12 2 nd TB period at CERN in this Autumn - 26 th November to 8 th December –Mainly AHCAL testbeam with 3 ScECAL layers We will put a Si layer in front of Sc layers Minimum-combined DAQ will be tested –Developing now –based on EUDAQ Planned test of combined DAQ

15. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 15 1.Hit objects To be used in high-level analysis Calorimeter hit is OK (may need minor change) 2.Simple array of raw data Important for debug and development LCGenericObject is usable (not elegant) Maybe we should require implementing new LCIO object LCIO over TCP is not easy, to be developed SDHCAL people plan to send object using ROOT Object separated in multiple files/machines Data format and issues in LCIO

16. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 16 LCIO: GenericObject LCIO Event  1 ROC - LCIO collections  1 types of data (SiADC, ScADC, ScTDC etc.) -LCIO objects LCGenericObject  1 chip of data LCGenericObject can save one array (int, float, double) dataDescription in every object can be used for tags, eg. “LDA=1;DIF=2;BX=10;”

17. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 17 Current status Succeeded to run EUDAQ with CaliceProducer producing dummy data encoded to LCIO object and save to LCIO file using DataCollector Ready to attach to calicoes/others

18. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 18 calice_soft: analysis package of calorimeters –Testbeam (Mokka) geometries –Raw to LCIO –Marlin processors Several steps of calibration (database?) output to ROOT trees(?) EUDAQ? –relation to EUtelescope DAQ and ilcsoft? and calicesoft?

19. Taikan Suehara, LCWS @ Belgrade, 9 Oct. 2014 page 19 Time to combine: we should start serious discussion of DAQ –to minimize effort and duplication before too much separation We are trying on Si/Sc combination Close collaboration with software group is also very important –Not so much software experts in each technology group...
