“…A serial power distribution system has been proposed to power the pixel modules because it minimises the amount of cables in the detector and is the only existing power solution that can tolerate the expected radiation levels since it is based on integrated on-chip shunt low dropout (Shunt-LDO) regulators. 1 In this scheme, a constant current is injected in a group of modules put in series and the current is fed from one module to the next one [2]. The total number of serial power chains in the CMS IT system is 500, with a maximum of 12 modules per chain.…”

A new Silicon Tracker will be built for the phase-2 upgrade of the CMS experiment. The innermost part, called the Inner Tracker, will be featuring high-granularity pixelated silicon sensors of 2500 µm2 and will need to cope with the unprecedented radiation levels of 1.9 Grad and 3.5 × 1016 neq/cm2 fluence and particle hit rates of 3.2 GHz/cm2. The pixel electronics system is based on innovative solutions such as a radiation hard pixel ASIC, the novel serial powering scheme used to power up to 12 detector modules in series and advanced technologies for the high bandwidth readout system based on electrical light-weight readout links of 1.28 Gbps, electrical to optical conversion as close as possible to the detector modules and back-end boards each one capable of receiving an aggregated data bandwidth of 190 Gbps. The recently optimised design of the CMS Inner Tracker electronics system will be presented in this contribution.

“…For this reason, serial powering has proven to be the only technically viable option to power some of the future detectors at LHC (i.e., ATLAS and CMS pixel detectors) [2,3]. This scheme creates a chain of multiple detector modules (readout chips and Si sensors) in series, where each device has its own internal linear regulators (Shunt-LDO [4]) to generate the voltage needed by the chip electronics.…”

This paper introduces a prototype of a GaN-FET based 200 W DC-DC converter. Its design has been carried out to evaluate power density (or power dissipation and volume) and ensure minimal electromagnetic interference (EMI) issues that are commonly associated with the high switching frequency converters. To achieve this ANSYS HFSS-SiWave models have been developed to assess noise emissions based on the parasitic elements of PCB layout. Prototypes performance have been evaluated through extensive testing. This work offers insight into the potential of this technology in future physics detectors.

“…An important aspect of the CMS IT design is the choice of serial powering scheme for the pixel modules [14]. The serial powering scheme dictates the grouping of the modules in serial power chains and no crossing of the readout or the sensor biasing is allowed among modules that belong to different chains (see Fig.…”

A new silicon tracker will be built for the Phase 2 Upgrade of the CMS experiment to fully exploit the increased luminosity delivered by the HL-LHC. The innermost part, called the Inner Tracker, will be exposed to extreme conditions such as unprecedented radiation levels of 1.2 Grad and 2.3×10 16 n /cm 2 and hit rate of 3.2 GHz/cm 2 . The new Inner Tracker relies on many novel solutions and technologies that allow for a design of a light and radiation-hard pixel detector of high performance. The hybrid pixel modules will be composed of pixel sensors with pixel size of 2500 μm 2 and a new ASIC, designed in 65 nm CMOS technology, developed by the RD53 collaboration. A novel scheme of serial powering will be deployed to power the pixel modules and new technologies will be used for a high bandwidth readout system. The mechanics will be lightweight, based on carbon-fibre material and two-phase CO 2 cooling. In this contribution, the design of the CMS Inner Tracker system will be presented along with the prospective design choices.
