SuperNEMO - Detector Efficiency

This repository holds a SN@ilWare configuration + source code to evaluate SuperNEMO detector efficiency. Given a bank label to look into, the module computes the efficiency of each sensitive detector volumes i.e. main wall calorimeter, X-wall calorimeter, γ-vetos and Geiger cells. An example of the use of this module is provided in this presentation.

The current version is hosted at https://github.com/xgarrido/snemo_simulation_modules/snemo_detector_efficiency under git version control.

The code itself is implemented in the source directory which holds the snemo_detector_efficiency_module.* source code as well as a CMakeLists.txt file in order to compile, build and install the module following cmake rules.

Module declaration

The next item holds the configuration for this module. The module name is detector_efficiency_module which is needed when using bxdpp_processing as explained in the top README file.

Special execution of this module

Since this module will actively use geometry manager and its locators (i.e. calo_locator, xcalo_locator,…), the module need to initialize and load the geometry service. The geometry service is actually called in this section by using the Geo service label as defined in "Geometry service" section. To properly load the Falaise configuration files for the geometry, we have to specify the path to these resource files by executing

bxdpp_processing                                                                              \
    --module-manager-config $PWD/config/module_manager.conf                                   \
    --module detector_efficiency_module_module                                                \
    --dll-config $PWD/config/dlls.conf                                                        \
    --datatools::resource_path=falaise@<path to Falaise instal>/share/Falaise-1.0.0/resources \
    --input-file <path to a data record>

The --datatools::resource_path option will automatically register this path and it will replace any of the @falaise: declaration into Falaise resource path.
