	Funding: Project supported by the Young scientists Fund ’Grant NO.11905075’ Because of determining the depth of Bragg Peak, range and energy of carbon beam are very important parameters in therapy. In order to measure those parameters rapidly, we design a multi-layer Faraday cup (MLFC). Simulation of proton beam and carbon beam are given in this paper. A prototype has 128 channels have been developed. Each consists of a 40 um copper foil and 600 um FR4 plate. A 128 channels electronics was used to measurement the deposited ions in each copper foil.

	The Wall Current Monitor (WCM) can monitor the lon-gitudinal beam shape, beam stability, beam longi-tudinal emittance and intensity, which has been ap-plied widely in the laboratories of high-current proton accelerators. Many accelerators such as CERN-PS, CERN-CLIC, J-PARC and CSNS-RCS have designed different WCMs according to their respective accelera-tor beam parameters. In order to provide the high-intensity heavy-ion accelerator facility (HIAF)-BRing high-frequency system of with the intensity of each harmonic beam to compensate for wake field; and to observe the changes of the bundle length during the injection, acceleration, and extraction of the bundle, it is planned to place a WCM in HIAF-BRing. According to physical requirements, the lower limit of the WCM work-ing bandwidth is expected to reach 10kHz, and the upper limit can reach 100MHz. According to this bandwidth re-quirement, a WCM structure is designed, and its theoretical bandwidth is 2kHz~400MHz, which fully meets the de-mand. This article gives a detailed and comprehensive in-troduction to the overall design of this WCM, the selection of various components, design calculations and related simulation calcula-tions. At present, the WCM has com-pleted the pro-curement and processing of various compo-nents, while offline and online testing has not been carried out owing to time constraints. It is expected to be in-stalled on the Heavy Ion Research Facility in Lanzhou-Cooling Storage Ring (HIRFL-CSR) for online testing in August.

The Wall Current Monitor (WCM) can monitor the lon-gitudinal beam shape, beam stability, beam longi-tudinal emittance and intensity, which has been ap-plied widely in the laboratories of high-current proton accelerators. Many accelerators such as CERN-PS, CERN-CLIC, J-PARC and CSNS-RCS have designed different WCMs according to their respective accelera-tor beam parameters. In order to provide the high-intensity heavy-ion accelerator facility (HIAF)-BRing high-frequency system of with the intensity of each harmonic beam to compensate for wake field; and to observe the changes of the bundle length during the injection, acceleration, and extraction of the bundle, it is planned to place a WCM in HIAF-BRing.
