but not a monolithic detector of 1 m^3. <br>

Title: The BDX detector for Light Dark Matter search at JLab<br>
<br>
Abstract:<br>
The BDX experiment will be the first modern large-scale electron beam<br>
dump experiment explicitly aimed to search for Light Dark Matter (LDM)<br>
within the MeV-GeV energy range. Scheduled to operate between 2026 and<br>
2029, BDX will utilise a 10 GeV beam with currents reaching up to 65 uA,<br>
and will accumulate over 10^22 electrons on target (EOT) over the full<br>
running period. Positioned downstream of the Jefferson Lab experimental<br>
Hall-A beam dump, BDX will run parasitically alongside the Hall-A<br>
experimental program.<br>
The BDX detector is optimised for Dark Matter detection and achieve<br>
remarkably high efficiency in background rejection. It will feature a 1<br>
m^3 active core composed by CsI(Tl) crystals, surrounded by a highly<br>
hermetic, multi-layer veto system. The innermost layer is made by a <br>
passive lead shielding, while the middle and outer layers consist of<br>
high-efficiency plastic scintillators designed to detect charged<br>
particles.<br>
In this contribution I will show main features of the BDX experiment and<br>
the detector. I will present the different variables that can be<br>
reconstructed and utilised in signal identification and background<br>
rejection. Additionally, AI-supported techniques to enhance background<br>
rejection and increase the experiment's sensitivity to Light Dark Matter<br>
signals will be presented.<br>
<br>
Let me know if you would change anything. I await your reply.<br>
Best regards,<br>
Marco S.<br>
