This report presents the status of HGCal silicon module mass production at the IHEP MAC, as part of the CMS High-Granularity Endcap Calorimeter upgrade for the HL-LHC. The IHEP MAC, one of six global silicon module assembly centers, focuses on low-density (LD) full silicon modules, with an expected workload of around 5,000 modules. The production chain includes hexaboard taping, electronic...

"The LHCb Upgrade II will operate at instantaneous luminosities up to 1.5×10³⁴ cm⁻²s⁻¹ and collect about 300 fb⁻¹ during the HL-LHC era. In the central region of the electromagnetic calorimeter this means MGy-level accumulated dose, more than 50 pile-up interactions per bunch crossing, and the need to keep an energy resolution of about 10%/√E ⊕ 1% while adding timing at the level of O(10 ps)....

The LHCb Upgrade II aims to operate at an instantaneous luminosity nearly an order of magnitude higher than that of Upgrade I, placing significantly greater demands on detector performance and reconstruction capabilities. To meet these challenges, a new electromagnetic calorimeter, known as PicoCal, is being developed with substantial improvements in both hardware and software. The redesigned...

The electromagnetic calorimeter (ECAL) of the LHCb experiment in Upgrade II, also known as PicoCal, features the new ability of time measurement. It is necessary that the timing performance of PicoCal is precisely reflected in the LHCb simulation program. The recent progress on the development of PicoCal timing simulation, alongside with the performance studies of the algorithms, are presented...
