Liquid PbBi Target in Solenoid Magnetic Field
PbBi Target Optimization
is this without a magnetic field? Answer:Yes.
Solenoid Magnet Simulation
G4beamline calculates field maps for solenoids using COMSOL
For RF cavities it uses Superfish

How do you change the B-field magnitude?
Answer: By changing the current of the dipole (current=).
param -unset SMI=200 SMIR=100 SMOR=120 SML=400 coil SMC innerRadius=$SMIR outerRadius=$SMOR length=$SML material=Cu solenoid SM coil=SMC current=$SMI color=1,0,1,0.5
The field points probed are print out in a file called Bout.txt The points to be probed are given in by the input file Bin.txt or given in the script (as shown in the end).
How can you tell the direction?
The field lines can be visualized by un-commenting the following line. #fieldlines exit=1 center=0,0,0 nLines=100 color=0,1,1,0.5
