[BDXlist] [EXTERNAL] Abstract for PM2024

[Marco Spreafico]

Dear Patrick,
thank you very much for your comments. I implemented the following 
changes:
- will utilise a 10 GeV beam --> will utilise a 11 GeV beam
- It will feature a 1 m^3 active core composed by CsI(Tl) crystals, 
surrounded by a highly hermetic, multi-layer veto system. --> It will 
feature a modular design, with each module made by a 0.25 m^3 active 
core composed by CsI(Tl) crystals surrounded by a highly hermetic, 
multi-layer veto system.
I kept the schedule between 2026 and 2029 to be consistent with the most 
recent BDX talks.
Best regards,
Marco
