The Belle II experiment at the SuperKEKB e+e- collider has started data taking in 2018 with the perspective of collecting 50ab-1 during the next several years. The detector is working well with very good performance, but the first years of running are showing novel challenges and indicate the need for an accelerator consolidation and upgrade to reach the target luminosity of 6E35 cm-2s-1,...
The addition of a Forward Calorimeter (FoCal) to the ALICE experiment is proposed for LHC Run 4 to provide unique constraints on the low-x gluon structure of protons and nuclei via forward measurements of direct photons.

Circular colliders have the advantage of delivering collisions to multiple interaction points (up to 4 IPs for e+e- collisions at the FCC-ee facility) that allow for different detector designs to be studied and optimized individually aiming at complementary physics target studies. On the one hand, the detectors must satisfy the constraints imposed by the invasive interaction region layout. On...

The aim of the LHCb Upgrade II is to operate at a luminosity of 1.5 x 10^34 cm^-2 s^-1 to collect a data set of 300 fb^-1. This will require a substantial modification of the current LHCb ECAL due to high radiation doses in the central region and increased particle densities. A consolidation of the ECAL already during LS3 would reduce the occupancy in the central region and mitigate...

It is well known that the lattice structure of a scintillating crystal can influence the development of the electromagnetic processes inside it. For electron and photon beams aligned with the symmetry axis of a crystal, if the strong field condition is satisfied, a reduction of the radiation length X$_0$ is expected. However, these effects have been experimentally observed only in the last few...
