I have added in the new shielding geometry. Two new models have been added. 'Basic Lab', and 'Lab with Improved Shield'. Basic Lab includes the support frame, Anti-Radon Tent and Magnetic coil, 'Lab with Improved Shield' shield includes these and the iron and polyethylene shields.

I have had to redefine the module_0 object to accurately include the magnetic coil. This has created other problems as follows:

  • Selecting 'basic_iron' shield will now include the magnetic coil. This is obviously not consistent with the previous versions of falaise. I have tried to change this but am not sure the best way to proceed so for now have left it like this.

  • When I perform flsimulate with a magnetic field there is a clash:
    flsimulate : Setup/run of simulation threw exception
    [void mctools::g4::detector_construction::_construct_electromagnetic_field():704: Missing G4 logical volume with name 'module_basic.model.log' !]
    (this does not affect the neutron simulations I have been performing but when others wish to use the new geometry to simulate events with a magnetic field there will be a problem). I am also not sure how to fix this so have left it like this and noted the problem.
