Description
In this report, we will introduce the current status of the Flex Tail (FT) and High Voltage Power Supply (HVPS) systems. In the ATLAS High Granularity Timing Detector (HGTD) project , the FTs are designed for the connection between detector module and Peripheral Electronics Board (PEB). According to different location in the detector sector, there are so many kinds of FTs with different length. The longest one can reach up to 70 cm long and 220 μm thick. Currently, we have completed prototyping with validated impedance and voltage drop performance, and is progressing in the pre-production. The HVPS is designed to bias the LGAD detector, delivering up to 800 V with 100 nA precision. So far, several HVPS prototypes produced by Chinese company have sent to CERN for quality assurance testing.In the meetings, we will report the details of the two.
