bggen is the Hall D photoproduction code that Rakitha Beminiwattha [email protected] imported for SoLID background simulations. The modifications were made to allow electroproduction event generation with this code. For now bggen can only produce events for proton target.

Jixie Zhang ([email protected]) changed it to be compiled and run in 64-bit mode. Jixie also made some improvments as below.

1. remove Hall-D software dependence
2. self create random seed if given seed is zero
3. add beam current and target parameters into input file
4. add radiator thickness into input file
5. enable coherence brem. only if ratiator thickness > 1.0E-6
6. clean up code, add more comment and make it look consistant.

Check HISTORY.txt for details.

==============================================================

Note that CERN & ROOT must be installed before compilation.

make;
bggen.Linux_x86_64.exe will be created.

mkdir build && cd build
cmake ../code
make
bggen will be created.

==============================================================

All input files have been placed in run dir.

cd run;
../bggen.Linux_x86_64.exe 

==============================================================

h2root bggen.nt bggen.root
h2root bggen.hit bggen.his.root

I happened to find that 'h2root' from root v5.28 or v6.10 and up can
convert the hbook file into root file in the above. root v5.30 - v5.34
can not.
