Unfortunately I will not be able to join today due to parenting. As you know, I can (and am happy to)
provide  orientation in any simulation topic related to gaseous detectors (conceptual level), and
help any student to get familiar with the ideas and get started.

Specifically, regarding my own personal interests, I'll be happy to do something on this front:

of which, logically, I'd like to do first Ar scintillation and then Ar-CF4 scintillation.
Including Penning-transfers under the same (purely microscopic) formalism is also a long-standing wish,
so we do not need to rely so strongly on parametrizations (tough goal!).
Including the above framework (e.g., the one in the above paper) in Garfield++ is not difficult, and I'll be happy to do, too.

I'd need one student, of which I could, potentially, fund 1/2. I am open to discuss
resistive spark-quenching simuls as well (I have an interest), under the same 1/2-1/2 scheme.

In the meantime, I'll try to make progress by making use of free time of PhD students, bachelor and
master, around here, using my academic environment.

I hope you manage to imprint a collaborative vision and effectively coordinate. Asking institutes to
contribute and expect things run on their own will not work, looking forward. It is a foregone conclusion.
One needs to achieve 1+1 > 2, I believe. One of the reasons is that it is very difficult to get PhD students
funded to work specifically on a simulation topic, but sharing could work. This is my own experience and
looks like a way to start.
