MCNP: Help constructing the geometry for this pinpoint chamber please

[Alexander Camargo]

I try to build this geometry in mcnp, but I'm having difficulties. Can anyone help me? I'm having a lot of trouble defining these curves. A small introduction will help me a lot.

This looks like it is for your schoolwork assignment, so please show us your work so far. Thank you.

It's not a school project, I have knowledge of mcnp, I just don't have experience with complex geometries
