Strips 1-16 dE.

Strip 8 is not working. Strip 16 is drowing the 10B peak in noise.  All others  look ok. The low energy peak around channel 300 in visible in some strips may be the Li recoil. The main peak around channel 800 is 10B(n,alpha_1) at around 1.3 MeV. The alpha_0 channel should be at around 1.8 MeV. There seem to be two small peaks above the alpha_1 peak. not sure why.

 

Plotted using:

 

void plotfile(){

    TFile *f=new TFile("run219173_B_ded.root","read");

 

    Char_t s[256];

    

    TH1D **hamps;

    hamps=new TH1D*[17];

    

    //creating histograms for each strip

    for(int u=0;u<=16;u++){

        sprintf(s, "hamp_%d",u);

        hamps[u]=(TH1D*)f->Get(s);

    }

    TCanvas *c=new TCanvas();

    c->Divide(4,4);

 

    for(int u=1;u<=16;u++){

        c->cd(u);

        c->SetLogy();

        hamps[u]->GetXaxis()->SetRangeUser(0,2000);

        hamps[u]->GetYaxis()->SetRangeUser(0,50);

        hamps[u]->DrawCopy();

  

    }

}
