Power, grounding and shielding
Oral
The described system is developed in the framework of a deep-sea submerged Very Large Volume neutrino Telescope where photons are detected by a large number of Photo Multiplier Tubes [2]. These PMTs are placed in optical modules (OM). A basic Cockcroft-Walton (CW) voltage multiplier circuit design is used to generate multiple voltages to drive the dynodes of the photomultiplier tube. To...

The development of a custom radiation-tolerant DCDC converter ASIC is under way, aiming at an input voltage of 10V and an output power up to 8W. CMOS technologies for the development have been tested for radiation, and two of them satisfied the specifications even for upgraded trackers to SLHC levels. The design of 2 ASIC prototypes is presented, with measurements indicating that both the...

Future detector systems will face technical difficulties with the supply of electrical power to a multitude of sub-detectors. The Serial Powering (SP) scheme is an elegant solution which leads to a great reduction in cable mass, whilst increasing efficiency and reducing cost. In recent years, substantial developments in SP have been made by the ATLAS Tracker Upgrade Community. Initial...

The CMS experiment foresees the deployment of DC-DC buck converters in its pixel and strip tracker upgrades, to facilitate the supply of the required currents with the installed cable plant and with a minimal amount of material.
We have developed DC-DC buck converters based on radiation-tolerant ASICs from the CERN electronics group. Their performance in terms of power efficiency and...

Powering of future trackers at SLHC requires low current distribution for high power efficiency and low material budget. In this framework, we investigate a serial powering scheme for the ATLAS pixel detector at SLHC. A dedicated regulator has been prototyped and largely characterized, both as single device and in a serial powering configuration. System aspects, such as AC-coupled module...

The development of front-end systems for the ATLAS tracker at the sLHC is now in progress and the availability of radiation tolerant buck converter ASICs enables the implementation of DC to DC converter based powering schemes. The front-end systems powered in this manner will be exposed to the radiated and conducted noise emitted by the converters. The electromagnetic compatibility between DC...
