The LHCb experiment is upgrading part of its detector and the entire readout system towards a full 40 MHz readout system in order to run between five and ten times its initial design luminosity and increase its trigger efficiency. In this paper, the new timing , trigger and control distribution system for such an upgrade is reviewed with particular attention given to the distribution of the clo...

We have designed, fabricated and tested an XYaddressable readout architecture for superconducting flux qubits in an integrated circuit designed to enable adiabatic quantum optimization algorithms. The readout architecture for an N-qubit system comprises N hysteretic dc SQUIDs and N rf SQUID latches controlled with 2 √ N +2 wires. The latching elements are coupled to the qubits and provide excep...

A cylindrical Time Projection Chamber [1], is the main tracking device of the dedicated heavy ion LHC experiment ALICE at CERN. Each end of the cylinder holds a readout plane which is subdivided into 18 segments in azimuth and two parts in radius (s. fig. 1). Both readout planes thus consist of 18 innerand 18 outer multiwire proportional readout chambers (IROC and OROC, respectively) with catho...

One strong constraint in ATLAS is the easy and fast access to the Tile calorimeter readout without any destructive interference with the rest of the detector. Therefore the drawer system has been designed to place all PMTs and associated electronics on a movable system inside the TILECAL girders which provide both, the structural support to the individual modules and the solenoid return ux. In ...

The elaboration of the signals provided by the fourstripline Beam Position Monitors (BPM) on the superconducting linac TTF will be accomplished by parallel rf circuits, giving a signal of ~1 V /cm, indipendent of beam current, for both horizontal and vertical beam positions with time response ~1μs. and useful range > ±1 cm The performances with respect to thermal drifts and input dynamics are p...

In the scope of the COMPASS experiment a multi-purpose, high rate capable TDC with digitisation width of 60 ps has been developed. The integration into the readout system and the flexible input of the CATCH readout driver is presented.
