Description
As ALICE is commissioning the detectors after major upgrades for the upcoming LHC Run 3, further projects are already on their way. R&D for a future upgrade of the Inner Tracking System has demonstrated the feasibility to operate thinned monolithic active pixel sensors bent to radii as small as 18 mm. In addition, it has been confirmed that large-scale wafers can be bent to such radii to form truly cylindrical sensors requiring only the silicon itself in the active area. This technique shall be used to replace the inner tracking layers and achieve unprecedented low material budget, reduced interaction probabilities, and unparalleled vertexing performance. We will discuss the results from the R&D programme and the prospects for the ITS3.
In addition, a novel concept for a Forward Calorimeter (FoCal) consisting of a high-granularity Si-W electromagnetic calorimeter with pad and pixel readout to provide unprecedented spatial resolution, and a hadronic calorimeter with conventional metal-scintillator technology with optical readout. The FoCal covers the pseudorapidity range from 3.4 to 5.8 to measure forward photon production to constrain the gluon PDFs down to very small x. We will show results from the R&D programme and the prospects for physics with the FoCal.
