Diffusion Monte Carlo

Goals

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

Calculations

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.

Special pm+p diffusion studies

Some model distributions for testing Steve's reconstruction algorithm

For both topics see elog

. Some thoughts on the efficiency differences and properties in Steve's formalism are collected here.

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.
