A high performance Time-of-Flight detector has been designed and constructed for isochronous mass measurement at CSRe. This detector consists of a Micro-Channel Plate(MCP)detector, a thin carbon foil(≈19 μg/cm2), which will emit secondary electrons while the ions pass through, and magnet and electrodes, which generate a perpendicular electric and magnetic field to guide the secondary electrons from the foil to the MCP[1]. The signals from the MCP are recorded by a digital phosphor oscilloscope Tektronix DPO 71254, and the revolution time of the ions can be extracted.
