“…These FPGAs have been extensively studied by multiple groups to characterize their behavior under radiation and the results of these tests validate their use in the HCAL front-end electronics environment. Of particular value are the extensive studies documented in [44].…”

“…According to studies from the manufacturer, SEL have been observed at linear energy transfer (LET) levels of 86.9 MeV cm 2 /mg and higher at room temperature and at an operating temperature of 125 • C [45]; another study [44] has observed SEL at LET levels of 55 MeV cm 2 /mg and higher. The typical LET for nuclear interaction in silicon, by far the most abundant material around the sensitive nodes of the chip, is around 16 MeV cm 2 /mg [46] which is far below the thresholds observed to cause SEL.…”

“…Over the expected total ionizing dose (TID) of 10 krads, ProASIC3 FPGAs remain fully functional -they do not exhibit an increase in power consumption or a deterioration in maximum clock frequency [44,48]. Additionally, the flash-based FPGA configuration and the flash-based user ROM are not upset by radiation [44,49] in the LET range of interest (up to 45 MeV cm 2 /mg).…”

This report describes the technical design and outlines the expected performance of the Phase 1 Upgrade of the CMS Hadron Calorimeters. The upgrade is designed to improve the performance of the calorimeters at high luminosity with large numbers of pileup events by increasing the depth-segmentation of the calorimeter and providing new capabilities for anomalous background rejection. The photodetectors of the CMS Barrel and Endcap Hadron Calorimeters, currently hybrid photodiodes (HPDs), will be replaced by silicon photomultiplier (SiPM) devices. The single-channel phototubes of the Forward Hadron Calorimeter will be replaced by multi-anode phototubes operated in a dual-anode configuration. The readout electronics for all three calorimeter systems will also be replaced. A new charge-integrating ADC, the QIE10, with an integrated TDC will be used along with a 4.8 Gbps data-link. The off-detector electronics will also be substantially upgraded to handle higher data volumes and improve the information sent to the calorimeter trigger system. The expected performance of these upgrades is discussed, including a detailed study of several Higgs and SUSY analyses. The planning for the implementation of this upgrade is presented, including construction, testing, and installation. AcknowledgmentsWe would like to thank the technical staff from the various institutions for the design, R&D and testing of the many components of this upgrade.We also wish to thank the LHCC for their oversight and crucial advice during the development of the HCAL Phase 1 upgrade project. We also acknowledge the warm support received from the CMS management team. The important feedback from following CMS internal reviewers greatly helped in the development of this technical design report: Finally, we dedicate this technical design report for the phase 1 upgrade of the HCAL subdetectors to the memory of our colleague
