This paper describes the implementation of a SPI-programmable clock delay chip based on a Delay Locked Loop (DLL) in order to shift the phase of the LHC clock (25 ns) in steps of 1ns, with a 4ps jitter and 18ps of DNL. The delay lines will be integrated into ICECAL, the LHCb calorimeter front-end ASIC in the near future. The stringent noise requirements on the ASIC imply minimizing the noise...

In the event of beam loss at the LHC, ATLAS inner detector components nearest the beamline may be subjected to unusually large amounts of radiation. Understanding their behavior in such an event is important in determining whether they would still function properly. We built a SPICE model of the silicon strip module electrical system to determine the behavior of its elements during a realistic...

A complex readout electronic chain has been designed for the EUSO-Balloon project. It contains two elements: the EC units (9 of them) and the EC-ASIC boards (6). The EC unit includes 64-channel Multi-Anode Photomultipliers and a set of pcbs used to supply the 14 different high voltages needed by the MAPMTs and to read out the analog output signals. These signals are transmitted to the EC-ASIC...

NA62 experiment Straw tracker frontend board serves as a gas-tight detector cover and integrates two CARIOCA chips, a low cost FPGA (Cyclon III, Altera) and a set of 400Mbit/s links to the backend. The FPGA houses 16 sub-nanosecond resolution TDCs with derandomizers and an output link serializer. Evaluation methods, including simulations, and performance results of the system in the lab and on...

The LHCb collaboration foresees a major upgrade of the detector for the high luminosity run that should take place after 2018. Apart from the increase of the instantaneous luminosity at the interaction point of the experiment, one of the major ingredients of this upgrade is a full readout at 40MHz of the sub-detectors and the acquisition of the data by a large farm of PC. The trigger will be...

A Verilog Behavioral simulation of sTGC trigger will be presented based on the current baseline concept with particular focus on the Level 1 latency obtained. Data for this trigger is taken from detector simulations with Garfield and PSpice, current measurements made in the existing small wheel, and FLUGG simulation of the arrival times of hits at high luminosities. These simulations will...

To continue triggering with the current performance in the LHC Run 2 the Global Muon Trigger (GMT) of the CMS experiment will be reimplemented in a Virtex-7 card utilizing the uTCA architecture. The thus available high-capacity input as well as increased logic could be used to migrate the final sorting stage of each subsystem to the GMT. Additionally the GMT will calculate a muonโs isolation...
