Diffusion Monte Carlo


  • Study P_out functions more carefully and with md+d scattering
  • Generate time and radius functions with "full kinetics" and understand them
  • Study range of mp diffusion with different scenarios and compare to Adamczak
  • Check effect of high energy pm's generated during cascade


study condition Cd (ppm) statistics output analyzed with
mudh2n mud in H2 0. 1e9 run/test/h2n.root make_h2.C->h2n.root, c_pout.C, plot_t("h2n.root", pout.C++
mudHD mud in H2+D 122. 1e8 run/test/mudHD.root make_h2.C->mudHD.root, c_pout.C, plot_t("mudHD.root", pout.C++
mupHD mup in H2+D 1.5. 1e8 run/test/mupHD mupHD.C, time, radius
mupHDC mud in H2+D 122. 1e8 run/test/mupHDC mudHD.C, time, radius

P_out function and decay rates

Extracted from mudh2n and mudHD simulation and already included in latest time analysis note.

Full kinetics range and time

mp+p hfs scattering
md+d hfs scattering
md+p scattering
mp->md transfer
ppm formation is not included, but could be.

Summary: Results follow expectations and document main features of diffusion processes. In principle, these results could be used for moment method or 3 par fit. But I leave that to Brendan, because his simulation better accounts for impact parameter and detector resolution.

Production condition: mupHD



Calibration condition: mupHDC



Special pm+p diffusion studies

Technical notes

Simulation directory is /home/npl/kammel/mucap/Mucat/run/test Run Mucat on windows machine with MCK_2.bat mupHD

This creates output in directory mupHD. Analyze on the local directory. Copy make_h2 root files to test directory and continue with c_out.C etc. Completed studies saved as mupHD.tar.gz, for example.
