A TRU consist of 16x28 // crystals ordered fNTRUPhi x fNTRUZ matrix. The algorithm searches all possible // 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the // digits amplitude and finding the maximum. Iti is found is maximum is isolated. // Maxima are transformed in ADC time samples. Each time bin is compared to the trigger // threshold until it is larger and then, triggers are set. Thresholds need to be fixed. // Usage: // // //Inside the event loop // AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger // tr->SetL0Threshold(100); // tr->SetL1JetLowPtThreshold(1000); // tr->SetL1JetMediumPtThreshold(10000); // tr->SetL1JetHighPtThreshold(20000); // .... // tr->Trigger(); //Execute Trigger // tr->Print(""); //Print data members after calculation. // // --- ROOT system --- class TClonesArray ; #include "TMatrixD.h" // --- AliRoot header files --- #include "AliTriggerDetector.h" class AliPHOSGeometry ; class AliPHOSTrigger : public AliTriggerDetector { public: AliPHOSTrigger() ; // ctor AliPHOSTrigger(const AliPHOSTrigger & trig) ; // cpy ctor virtual ~AliPHOSTrigger(); virtual void CreateInputs(); //Define trigger inputs for Central Trigger Processor void Print(const Option_t * opt ="") const ; virtual void Trigger() {} //Make PHOS trigger void Trigger(TClonesArray *digits); //Make PHOS trigger //Getters Float_t Get2x2MaxAmplitude() const {return f2x2MaxAmp ; } Float_t GetnxnMaxAmplitude() const {return fnxnMaxAmp ; } Int_t Get2x2CrystalPhi() const {return f2x2CrystalPhi ; } Int_t GetnxnCrystalPhi() const {return fnxnCrystalPhi ; } Int_t Get2x2CrystalEta() const {return f2x2CrystalEta ; } Int_t GetnxnCrystalEta() const {return fnxnCrystalEta ; } Int_t Get2x2SuperModule() const {return f2x2SM ; } Int_t GetnxnSuperModule() const {return fnxnSM ; } Int_t * GetADCValuesLowGainMax2x2Sum() {return fADCValuesLow2x2; } Int_t * GetADCValuesHighGainMax2x2Sum() {return fADCValuesHigh2x2; } Int_t * GetADCValuesLowGainMaxnxnSum() {return fADCValuesLownxn; } Int_t * GetADCValuesHighGainMaxnxnSum() {return fADCValuesHighnxn; } void GetCrystalPhiEtaIndexInModuleFromTRUIndex(Int_t itru, Int_t iphitru, Int_t ietatru,Int_t &ietaMod,Int_t &iphiMod) const ; Float_t GetL0Threshold() const {return fL0Threshold ; } Float_t GetL1JetLowPtThreshold() const {return fL1JetLowPtThreshold ; } Float_t GetL1JetMediumPtThreshold() const {return fL1JetMediumPtThreshold ; } Float_t GetL1JetHighPtThreshold() const {return fL1JetHighPtThreshold ; } Int_t GetNTRU() const {return fNTRU ; } Int_t GetNTRUZ() const {return fNTRUZ ; } Int_t GetNTRUPhi() const {return fNTRUPhi ; } Int_t GetPatchSize() const {return fPatchSize ; } Int_t GetIsolPatchSize() const {return fIsolPatchSize ; } Float_t Get2x2AmpOutOfPatch() const {return f2x2AmpOutOfPatch; } Float_t GetnxnAmpOutOfPatch() const {return fnxnAmpOutOfPatch; } Float_t Get2x2AmpOutOfPatchThres() const {return f2x2AmpOutOfPatchThres; } Float_t GetnxnAmpOutOfPatchThres() const {return fnxnAmpOutOfPatchThres; } Bool_t Is2x2Isol() const {return fIs2x2Isol; } Bool_t IsnxnIsol() const {return fIsnxnIsol; } Bool_t IsSimulation() const {return fSimulation ; } Bool_t IsIsolatedInModule() const {return fIsolateInModule ; } //Setters void SetDigitsList(TClonesArray * digits) {fDigitsList = digits ; } void SetNTRU(Int_t ntru) {fNTRU = ntru ; } void SetNTRUZ(Int_t ntru) {fNTRUZ = ntru ; } void SetNTRUPhi(Int_t ntru) {fNTRUPhi = ntru ; } void SetL0Threshold(Int_t amp) {fL0Threshold = amp ; } void SetL1JetLowPtThreshold(Int_t amp) {fL1JetLowPtThreshold = amp ; } void SetL1JetMediumPtThreshold(Int_t amp) {fL1JetMediumPtThreshold = amp; } void SetL1JetHighPtThreshold(Int_t amp) {fL1JetHighPtThreshold = amp ; } void SetPatchSize(Int_t ps) { fPatchSize = ps ; } void SetIsolPatchSize(Int_t ps) { fIsolPatchSize = ps ; } void Set2x2AmpOutOfPatchThres(Float_t th) { f2x2AmpOutOfPatchThres = th; } void SetnxnAmpOutOfPatchThres(Float_t th) { fnxnAmpOutOfPatchThres = th; } void SetSimulation(Bool_t sim ) { fSimulation = sim ; } void SetIsolateInModule(Bool_t isol ) { fIsolateInModule = isol ; } private: AliPHOSTrigger & operator = (const AliPHOSTrigger & trig) ;//cpy assignment void FillTRU(const TClonesArray * digits, const AliPHOSGeometry * geom) const ; Bool_t IsPatchIsolated(Int_t iPatchType, const Int_t imod, const Int_t mtru, const Float_t maxamp, const Int_t maxphi, const Int_t maxeta) ; void MakeSlidingCell(Int_t mod, TMatrixD &max2, TMatrixD &maxn) ; void SetTriggers(Int_t iMod, const TMatrixD &max2,const TMatrixD &maxn) ; void DoIt() ; private: Float_t f2x2MaxAmp ; //!
