Three BPM types are now in pre-series production, with two more variants under design. Close to the collision point, a set of cryogenic directive coupler BPMs equipped with a brand new acquisition system based on nearly-direct digitization will resolve the position of the two counter-rotating LHC beams occupying a common vacuum chamber. Other new button and stripline BPMs will provide not only the transverse beam position, but also timing signals for the experiments, and diagnostics for the new HL-LHC crab cavities. This contribution summarizes the HL-LHC BPM specifications, gives an overview of the new BPM designs, reports on the pre-series BPM production status and plans for series manufacturing, outlines the foreseen acquisition system architecture, and highlights the first beam measurements carried out with the proof-of-concept electronics for the directive stripline BPMs. PB - JACoW Publishing CP - Geneva, Switzerland SP - 408 EP - 412 KW - cryogenics KW - vacuum KW - pick-up KW - electron KW - electronics DA - 2022/12 PY - 2022 SN - 2673-5350 SN - 978-3-95450-241-7 DO - doi:10.18429/JACoW-IBIC2022-WEP12 UR - https://jacow.org/ibic2022/papers/wep12.pdf ER -
