  1. Status of the Athena Software for the Combined HEC/EMEC Testbeam Margret Fincke-Keeler Univ. of Victoria LArg Week Nov.19, 2002 • Combined HEC/EMEC testbeam data can be read • and analyzed within the ATLAS Athena framework • A “cookbook” gives an introduction for how to • access the data in Athena

  2. Athena Algorithms for Analyzing Combined HEC/EMEC Testbeam Data • At present: Use Athena version 4.0.0 • It is maintained in the hectbmon repository. • The development of this code is still under way. • At the beginning of October code was committed to the ATLAS repository • under version 4.4.0 - Do NOT use this version! It is for the software • architecture development team only. Margret Fincke-Keeler University of Victoria

  4. LArTBSignalContainer contains Information that is specific to “our” testbeam : Information for every read-out cell (e.g. TDC time, geometry,...) Pointers to all LArTBSignal information for each cell Information that is the result of a LArHECTBAna/LArTBSignalBuilder subalgorithm (e.g.: net signal peak - height (in ADC or nA) and time) … Look up the information available in .h files: LArTBSignal.h LArTBSignalContainer.h Margret Fincke-Keeler University of Victoria

  5. Example: In LArTBSignal.h: /** Get signal peak calculated by Polynomial (unit=adc count, NO pedestal subtraction) */ float get_CubicPeakADC() const { return m_CubicPeakADC; } /** Get pedestal from PedPara */ float get_pedestal() const { return (m_PedPara != 0) ? m_PedPara->get_mean() : 0; } In user program (this example: LArDigAna.cxx): for (pSignal = pSignalBegin; pSignal != pSignalEnd; pSignal++) { float cubsig = (*pSignal)->get_CubicPeakADC() - (*pSignal)->get_pedestal(); } Margret Fincke-Keeler University of Victoria

  6. Testbeam Analysis Package TB Reconstruction LArHECTBAna Athena (Sub-)Algorithms for Analysis: - Perform pedestal subtraction. - Find signal peak with either cubic fit digital filtering. - Find useful TDC timing (see talk by M. Lefebvre). - Perform ADC g nA calibration - Obtain eta, phi and z index for any given cell number. - Produce a standard Ntuple for HEC testbeam data taken before 2002. Examples for how to create your own histograms.

  7. HEC/EMEC Testbeam Athena Cookbook Find it on the web page for the EMEC+HEC 2002 Combined Run Information http://emecheccombined.web.cern.ch/EmecHecCombined/ It gives in depth instructions on how to get started running Athena code to read the HEC/EMEC combined testbeam data. Margret Fincke-Keeler University of Victoria

  8. How to set up your environment to access testbeam data under • Athena version 4.0.0 (…from scratch). • Create a pedestal file. • Create a standard HEC Ntuple (this only works for data taken • up to 2001 – so far there is no standard Ntuple for the combined • testbeam of Aug./Sept. 2002). • Create your own Athena algorithm. • Access some of the raw data taken during the combined run. • Produce a ROOT Tree and read it. • Where to find information to proceed on your own. Margret Fincke-Keeler University of Victoria

  9. Technical talks and progress: see minutes of the HEC/FCAL combined test beam meeting • Vincter: Noise studies in EMEC/HEC • Strizenec: Status of Calibration • McPherson: EMEC filtering weights with FFT Algorithm • Lefebvre: Filtering weight synchronization and timing • Menke: EMEC and HEC timing • Fincke-Keeler: Status of beam test ATHENA software • Kurchaninov: HV correction from beam test data Open issues for the future • Integration into production ATHENA • How far do we want to take this ? • Integration with other ATHENA packages ??? Margret Fincke-Keeler University of Victoria

  10. Conclusions Athena version 4.0.0 is available for reading data taken during the combined HEC/EMEC testbeam period in 2002. Detailed instructions on how to get started using the Athena environment can be found in a “cookbook”. Used for many studies reported at this LArg week. Open question: integration into ATHENA?
