  • Creating a cluster-based digitization algorithm for IDEA Muon-system
  • It clusters the simHits located in the same uRWELL chamber within specific cluster-size (number of strips fired by avalanche) into one digiHit, the value we get from test-beam results.
  • The goal is to cluster the secondaries (mainly delta-rays) lies within specific radius away from primary into one cluster, and not many separate digiHits.
  • The code also doing the same task as DDPlanarDigi for smearing hits positions and time, and applying efficiency filter.
  • It was better to have all digi steps of muon-system in one, instead of calling many different algorithms in steering files because of the requirements of specific types of inputs and associations, and to avoid complexity.
  • There's aslo a forcing hits into surface to avoid hit positions outside the chamber surfaces.
  • We expect further developments in that MUONDigi for extra digitization steps in future

Can we find a better name than MUONdigitizer? We discussed this in a call recently and our current names are not great. We agreed that a good name would give some indication of what the algorithm actually does. I would say forget about DDPlanarDigi and let's think about a completely new name. MUONdigitizer sounds like it's the default for muons for all detectors.

Hi @jmcarcell , thanks for your comments.
For the name what about MuonSystemDigitizer ?
I'd like to hear also from @BrieucF and @s6anloes
