Status of (n,a) Measurement with CVD Diamond Detector Weiss Christina 12.04.2011
Introduction • Data Analysis of Testbeams 2010 • Measurements • Analysis • Status for 2011 • Detector • Sample (n,a) with CVD diamond
Measurements 2010 • pCVD diamond detector : • En > 6 MeV • 200 mV/div • Background measurement • sCVD diamond detector : • En > 100 eV • 10 mV/div • 200 mV/div • Background measurement • 0.1 mm PE foil as converter (recoil protons) (n,a) with CVD diamond
Raw Data Recovery time after g-flash < 200 ns (n,a) with CVD diamond
Raw Data, Cuts Threshold = 20 mV Max Width = 10 ns (n,a) with CVD diamond
Amplitude versus Area (n,a) with CVD diamond
Experimental Data (n,a) with CVD diamond
12C Cross Section Data (n,a) with CVD diamond
Amplitude Spectrum: 1 MeV < En < 20 MeV Threshold (n,a) with CVD diamond
Preliminary Results : 1 MeV < En < 20 MeV CENDL CENDL (n,a) with CVD diamond
Next Steps • Check TOF – energy conversion • Reassess cuts • Baseline restoration • Take other material into account (esp.: Al, Cu) Simulation ? • Make analysis for the data with converter • Pulse shape analysis (n,a) with CVD diamond
10B (n,a) Measurement, 05.2011 • Detector • Metallization of the pCVD diamond: 19. – 20. April 2011 • PCB‘s: in production, expected by end of April • Detector housing: ready • Sample • W. Vollenberg: expected by end next week (n,a) with CVD diamond
Everything ongoing, nothing finished! Thank you for the attention!
