Hi Mariangela.

Please make sure that BDX-MINI is consistent.   You have also BDX-mini.

This is a very nice abstract!   It reads well.

Cheers,
Phil

Dear all,

the organizers of NuDM2022 invited me to submit a contribution for this conference. I prepared it inspiring to the abstract submitted by Andrea to ICHEP2022. Following you can find title and abstract. Any comment or suggestion is really welcome - I’ll submit the abstract on Tuesday (sorry for little time!).

Bests,

Mariangela

Title: Light Dark Matter Factory @ JLAB
Abstract: Jefferson Lab features several experiments to search for new light particles possibly explaining the Dark Matter problem. Among them, BDX (“Beam Dump Experiment”) aims to produce and detect Light Dark Matter (LDM) particles in the MeV-GeV mass range. It will exploit the high-intensity 10.6 GeV e- beam from CEBAF accelerator directed upon the Hall-A beam dump.  Any LDM particles produced by the interaction of the primary e- beam with the beam dump will be detected by measuring their scattering inside a detector, which is to be installed in a dedicated underground facility, located 20 m downstream. The space between the beam dump and the detector will be filled with heavy shielding to suppress the high-energy component of the beam-related backgrounds. The BDX detector consists of a CsI(Tl) electromagnetic calorimeter (ECAL) surrounded by a hermetic veto system.
The BDX proposal received full approval by the 2019 JLab Program Advisory Committee. While preparing for the design and construction of a new subterranean hall downstream of the existing Hall-A beam dump, the BDX collaboration fabricated and deployed a reduced version of the full detector, BDX-MINI, performing a first, preliminary search for LDM at lower beam energy. In this talk, after a brief introduction to the LDM physics case, we will present an overview of BDX, discussing the main items of the R&D and design phase of the experiment. We will then show the results obtained from the BDX-mini experiment, focusing on a few key aspects of the associated experimental campaign and data analysis effort.
