[Gate-users] Help in DNA physics

[Cassandra Miller]

Hi Noura,

Using the DNA physics list is relatively simple. The command is:

/gate/physics/addPhysicsList emDNAphysics

The caveat being, it ONLY works if you are using a specific material, 
G4_WATER:

/gate/nucleus/setMaterial G4_WATER

If you use regular water, it won't work, it has to be G4_WATER. You can 
also combine physics lists, for example if you have two spheres and 
sphere 2 doesn't require the dna list, you can do something like this:

/gate/sphere1/setMaterial G4_WATER
/gate/sphere2/setMaterial OtherMaterial

...

/gate/physics/addPhysicsListMixed emstandard_opt3_mixed_emdna
/gate/physics/SetDNAInRegion sphere1

/gate/physics/ConstructProcessMixed

And then sphere1 will be simulated using the dna list, and sphere 2 with 
the standard list. (if you google "/gate/physics/ConstructProcessMixed" 
you can find some more examples of this).

Best,
Cassandra
