• MCP detector
• Polynomial
• Position spectrum calibration

Microchannel Plate(MCP) detectors are widely applied in measuring the position of the reaction products in collisions of heavy ions with atoms, molecules, or solid targets. The directly measured two-dimensional position spectrums usually suffer from certain nonlinear distortions, which brings many difficulties to the subsequent data analysis. Based on polynomials, we develop a fitting-interpolating calibration method for the two-dimensional spectrums. This method is applied to the calibration of an MCP detector with a novel resistive anode, and gives rather good nonlinearity corrections. In general, this method relaxes the experimental requirements on the MCP detector anodes, and in turn makes the later more widely applicable.
