AMBER — En route to measure the proton radius
After months of excitement and almost continuous, frenetic activity since August, AMBER’s vast experimental hall — more than 10 m high and stretching over 60 m from the upstream collimators to the far wall — now feels unusually quiet and solitary.…

White Rabbit: Revolution of Timing Distribution for HL-LHC experiments
As CERN prepares for HL-LHC, fine timing is becoming a critical factor for success, especially for detectors aiming to time-tag hits to a precision of tens of picoseconds. For decades, the good old Timing, Trigger, and Control (TTC) backbone has…
