DUTs
Sim of test beam on the spot !Consider this extremely simple test beam setup.
- The placement of a detector defines the sensor as a sensitive volume.- The user can make a choise about the level of detail in the geometry.- The user can define new geometries. Number of pixels, size of the
pixel based on a XML template to meet its requirements.- The user can connect different digitizers or write its own and connect it .- Allpix is a digitizer implementation work-bench.- The user can include complicated geometries through GDML and
define parts as sensitive if the user needs to score there.

Mimosas and Al holdersthrough GDML
Scinti and trigger system
A more complicated example. The EUDET telescope.
- 6 DUTs and 6 Mimosas26 connected to 2 different digitizers.- The output comes natively in MAFalda format. Other formats have been
supported by users. LCIO is an example. A simple pixel matrix format is also available.
- Scintillators are an appliance just like the Al holders but are defined to be sensitive. An extra piece of code makes them behave as a trigger system.

Digitization It comes when the hitCollection of a SD is ready.
Geant4 implements a pure virtual G4VDigitizerModue::Digitize
Allpix digitization environment Allpix implements a wrapper to Digitization that allows to user to:
1) Connect different available digitizers to the same detector and compare results.
2) Create a new digitizer (C++) and connect it as any other.
3) User the digitizer service as an external lib to be used from a different infrastructure.

There might be more than 1 contour at the level where the bulk contour was found.
The three extra contours found at the same level than the first enveloping contour (bulk) will not be included in the skirt volume.
level = 25.9 keV
