@bfonta as this PR is still not what we agreed upon at the last TICL meeting, can you clarify what your plans are? |
|
@felicepantaleo The logic that ensures the shower is contained within HGCAL and still points to a reasonable R at the Z=0 plane is not trivial, and already depends on quite a few user options. I think keeping the displaced gun separate from the closeby gun simplifies the existing workflows, and also makes it clear for a potential user which gun to use when running displaced studies. |

PR description:
This PR introduces a displaced particle gun producer, and adds corresponding workflows.
The producer is useful for studies considering displaced topologies.
The producer selects a vertex position by randomly generating a set of$R>0$ , $\phi_{\text{Vtx}} \in [0;2\pi[$ , and $z>0$ coordinates. The momentum of the particle is then randomly generated using $p_{\text{T}}$ , $\theta \in [0, \pi[$ and $\phi \in [-\pi; \pi[$ coordinates. The vertex displacement $R$ can be generated uniformly along $R$ , or uniformly along the area of an annulus of radius $R_{\text{max}}-R_{\text{min}}$ .
The gun can be forced to only generate particles reaching the surface of HGCAL via the$\theta$ and $\phi$ are generated multiple times until a configuration enables the particle to lie within $\theta$ range is not sufficient to guarantee that a particle is produced in the right direction. By default, $R=200\text{cm}$ traverse the entirety of the CE-E. The
PointingToHGCALflag. In this case,RminFrontSurfaceHGCALandRmaxFrontSurfaceHGCAL. Note that, given a displaced vertex, setting only aRminFrontSurfaceHGCALandRmaxFrontSurfaceHGCALdelimit the inner third of HGCAL's front surface, ensuring virtually all showers produced up toPointingToHGCALflag cannot be used with charged particles, since their curved trajectories under the magnetic field breaks the implemented logic.PR validation
