The Upgrade of the LHCb detector

“[m]ore so than any other American author of the twentieth century, Pynchon documents in fiction the tectonic movements of American history, to the extent that

- Tests on FPGA code: the evaluation board will allow to test the specific code for the mezzanines architecture, the GBT interfacing code and specific technics as TMR for

As the ECAL trigger electronics is organized in 32 channel board, each 64 channels PS Front-end board is seen by the trigger system as two 32 channels half boards, each receiving

n Digital electronics design (front-end board) partly common n Same crate with a dedicated backplane for trigger treatment. Components have been tested

L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des

All the main characteristics were measured for five active boards out of 8: pedestals, DAC linearity, S-curves (trigger efficiency as a function of the injected charge or

As expected the so called s-curves are observed with a trigger efficiency going from a constant (plateau) value to 0. Increasing the amplitude of the LED increases the level

Figure 8.12 displays the interaction cross section of particles as a function of the energy of the beam and the position of the FPGA for the configuration memory resulting
