In 2019 the LHCb experiment will be upgraded to increase the read out rate from 1 MHz to 40 MHz. As a consequence all the front-end of all the sub-detectors will need to be replaced. The RICH detectors are currently equipped with Hybrid Photon Detectors (HPDs) with embedded electronics. In order to cope with the new read out rate, the photon detectors as well as the front-end electronics will be replaced. Moreover the increase in occupancy foreseen after the upgrade will require the complete re-design of the optics of the upstream detector (RICH1).
I will report on the design of the new RICH detectors, the tests performed with particle beam and the quality assurance tests the carried out on the components in production so far.
Speaker: Dr. Silvia Gambetta (University of Edinburgh)
Dr. Silvia Gambetta did her PhD in astroparticle physics, working for Auger. Her thesis was on the development of a new technique to detect Extensive Air Showers radio emission. She then joined LHCb during her first post-doc in Genova (2013). She worked on the tests of MaPMTs, the development of the baseboard, thermal characterisation of the Elementary Cell and she got involved in testbeams. In 2015 she moved to Edinburgh, continuing her work on testbeams. She has been responsible of the assembly of the testbeam setup and the testbeam operations for the past three years. In Edinburgh she is responsible for the design and realisation of the test stations for the Photon Detector Quality Assurance (selection and validation of the electronics, design of the mechanics, commissioning of the test stations). Since 2017 she is responsible for the current RICH operations, and she is the PI for the Quality Assurance of the Elementary Cell in Edinburgh.
