      SiPM R&D for LHCb 30m

      At RAL, we have just started working on the characterization of SiPMs for LHCb upgrade 2 (LHC Run 4 and Run 5). I will present our plans.

      The MIGDAL experiment : Towards observation and measurement of the Migdal effect to help low mass WIMPs searches 30m

      The Migdal in Galactic Dark mAtter expLoration (MIGDAL) experiment aims to make the first observation of the Migdal effect from fast neutron scattering using intense DT and DD generators, allowing the effect to be investigated over a wide range of nuclear recoil energies. The experiment will use an Optical Time Projection Chamber equipped with glass-GEMs operating in 50-Torr CF4 based gas mixture , with light and change readout provided by a CMOS camera, a photomultiplier tube, and a 120 strip anode. This will allow precise three-dimensional reconstruction of the ionization tracks from electron and nuclear recoils. A Migdal event will be identified by two ionization tracks sharing the same vertex, one belonging to a nuclear recoil and the other to a Migdal electron. Low pressure gas will enable the reconstruction of low energy tracks of electrons down to energies of 5 keV.
      I will report on the status of the detector commissioning and preparations for the experiment at the Neutron Irradiation Laboratory for Electronics (NILE) of the Rutherford Appleton Laboratory, UK
