Description

In this paper, the HiBeam-T, a time projection chamber (TPC) for monitoring the position and profile of heavy ion beams in a real-time manner, has been designed. This gaseous detector features its readout with an array of forty Topmetal-II− CMOS pixel sensors, each of which has 72 x 72 pixels with a size of 83 μm x 83 μm. The detector part consists of the charge drift and charge collection regions, separated by a gating grid. The readout electronics consists of three readout control modules and one clock and synchronization module. This Hibeam-T has a sensitive area of 20×20 cm2, and it can acquire the one-dimensional beam position and profile every second. A test with a continuous 80.55 MeV/u 12C6+ beam shows that the measurement resolution to the beam center could reach 17 μm.
