文摘
The energy resolution of a superconducting tunnel junction particle detector was significantly improved by the addition of a metal mesh infrared-blocking filter. The energy resolution was 138–215 eV full width at half maximum for 1.5–3.0 keV Ar ions. The infrared-blocking filter reduces the loss of energy resolution due to infrared radiation at room temperature.
