abstract = {{A compact IPM structure is proposed and developed for the HIAF project (High Intensity Heavy-ion Accelerator Facility), which is capable of measuring both horizontal and vertical profiles by simply changing the E-field. Its installation space is reduced to be only half comparing to that of a conventional IPM. A ceramic substrate PCB coated with copper anodes is used to collect electrons after the MCP output. A 64-channel data acquisition system based on the trans-impedance amplifier, ADC, FPGA and ARM is developed as well with a fast response of 1 MHz. To decrease the trajectory distortion during the electron collection, a bipolar magnet with a square shape is designed to correct the horizontal or vertical profile errors. In summer 2021, the compact IPM had been tested in Low Energy Accelerator Facility at IMP (LEAF, IMP) with the 0.5 MeV/u carbon beams. It obtains the profiles successfully in both directions. And the comparison between an upstream wire scanner and the IPM has also been done. Additionally, the magnet field shows a significant suppression effect during the signal collection. Despite some minor discrepancies, the beam experiments show a reasonable and good result.}},
