Detalhes bibliográficos
Resumo:To comply with the increase in luminosity of the LHC (Large Hadron Collider) in the next decades, the electronics of the ATLAS (A Toroidal LHC Apparatus) experiment is being upgraded. Included in the upgrade is the interfacing and control electronics system of the HVOpto/HVRemote cards in the TileCal (Tile Calorimeter) detector, which provides high voltages to about 104 photomultipliers (PMTs). This paper presents the new interfacing architecture for the system and details the design of a prototype control board (HVRemote-Ctrl) used for test and validation of the new architecture. The tests evaluate the system multiplexing capabilities needed to monitor all the TileCal PMTs in real time. The communication channels involved, supported in Ethernet and SPI interfaces/protocols, have been fully tested. Some results from the tests already completed are presented.
