Radiation hard programmable delay line for LHCb calorimeter upgrade
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 less than 5 ps jitter and 23 ps of DNL. The delay lines will be integrated into ICECAL, the LHCb calorimeter front-end analog signal processing ASIC in the near future. The stringent noise requirements on the...
متن کاملStudy of a solution with COTS for the LHCb calorimeter upgrade
We present a solution made out of Components Out of Shelf (COTS) for the analog processing of the signal of the LHCb calorimeters in the framework of the foreseen upgrade of the detector. The present proposal is based on the current functional solution, yet, to meet the stringent noise requirements, a number of modifications are proposed. Preliminary results on the prototype boards show promisi...
متن کاملThe LHCb upgrade detector
The LHCb experiment has been designed to perform precision measurements of CP asymmetries and to investigate potential effects of physics beyond the Standard Model. Results obtained from data collected in 2010 and 2011 show that the detector is robust and functioning well. While LHCb will be able to measure a host of interesting channels in heavy flavour decays in the coming years, a limit of a...
متن کاملLHCb upgrade plans
The LHCb experiment will operate for about five years at a luminosity of 2 × 10 cms and plans are to accumulate a data sample of ∼ 10 fb. Here we present the physics programme and detector design for a future high luminosity phase of the LHCb experiment. An upgraded LHCb experiment would operate at ten times the design luminosity, i.e. at ∼ 2×10 cms and aims to collect a data sample of ∼ 100 fb...
متن کاملThe LHCb Upgrade
Future flavour physics experiments will be required in the second half of the next decade to either elucidate the flavour structure of new particles discovered at the LHC or to probe new physics at the multi-TeV scale. The planned upgrade of the LHCb detector involves at least five years of operating at ten times the current design luminosity, i.e. at about 2×10 33 cm −2 s −1. The aim is to col...
