Introduction

I. Dawson
This report documents the knowledge and experiences gained by the LHC experiments in running vertex and tracker detector systems in extreme radiation environments and concludes a series of workshops held at CERN. By the time of the workshops, the last one held on February 2019, the LHC machine had delivered a large fraction of the design luminosity to the experiments and the deleterious effects of radiation on detector performance and operation were being observed and...

Controls technologies

J. Serrano
By the time of the commissioning and subsequent operation of the HL-LHC, many of the physical elements of the control system will have been upgraded due to obsolescence. This applies particularly to the front and back end CPUs and storage. It is not, however, foreseen that the overall control system strategy and architecture will change in its conceptual structure during this period, and many parts of the current controls infrastructure will still be sufficient for...

Measurements of radiation damage on silicon sensors

Lima, A. Macchiolo, J. Llorente Merino, K. Mochizuki, B. Nachman, G. Sarpis, S. Seidel, J. Sonneveld, S. Tsuno … & R. Wang
This chapter is organized as follows. Section 5.1 introduces, for each experiment, aspects of the detector set-up and measurement methods particularly relevant for the measurements. Next, the models used to interpret the data are summarized in Section 5.2. Then, in Section 5.3, we present the measurements for the above observables. The chapter ends with discussion and outlook in Section 5.4.

Since the previous TDR version 0.1, the hardware development has made significant progress. The universal quench detection system, CLIQ and energy extraction system prototypes have been successfully produced and tested and first units have been successfully deployed and used in SM18. This progress is reflected in the Sections below and some of the previously retained options have therefore been removed. In addition, the development of the quench heater power supplies for the HL-LHC is well...

CERN Yellow Reports: Monographs, Vol. 1 (2021): Radiation effects in the LHC experiments: Impact on detector performance and operation

Editor: I. Dawson This report documents the knowledge and experiences gained by the LHC experiments in running detector systems in radiation environments during 2010–2018, with a focus on the inner detector systems. During this time, the LHC machine has delivered a large fraction of the design luminosity to the experiments and the deleterious effects of radiation on detector operation are being observed and measured. It is timely to review the findings from across the experiments....
