Detector development for a Lyman- a imager Udo Schühle
1
Detector development for a Lyman- imager Udo Schühle Camera design Camera design: A CMOS-APS detector is mated with a micro-channel plate intensifier that is coated with KBr to increase efficiency around 121 nm and reduce the efficiency above 160 nm. The MCP-intensifier with a phosphor screen output window will be mated with the APS-sensor by a fiber-optic block. Sensor and electronics: Sensor and electronics: • STAR-1000 with 1024 x 1024 pixels • electronic system designed and built entirely by MPS • low-noise 14-bit ADC electronics • USB interface for PC operation • all radiation-hard design Photocathode deposition chamber and VUV vacuum test chamber Selective photocathode coating and performance at 121.6 nm Intensifier testing: Intensifier testing: • photocathode deposition (KBr, CsI) • VUV testing and characterization, calibration
