HBD support structure in PISA
After some discussion between Charlie, Hugo, Hubert and myself there was a common agreement that this HBD support structure should be a part of the list of PISA “Passive Volumes” like beam pipe, magnets, helium bag etc.
The code ‘hbd_support.f’ will be in CVS in directory ‘simulation/pisa/src/phnxcore’.
I’ve defined in ‘gugeom.f’ a new parameter ‘HBDS’ which should be used in ‘pisa.kumac’.
In order to perform the proper comparison I’ve generated 1M pi^0 Dalitz decays in 4 different setups:
1. (++) magnetic field w/o HBD and w/o its support;2. (++) magnetic field w/o HBD but w/ its support (Run-8);3. (++) magnetic field w/ HBD and its support (Run-9 500 GeV);4. (+-) magnetic field w/ HBD and its support (Run-9 200 GeV);
