Absolute calibration of the spectral sensitivity of detectors in the VUV range. Мeasurement procedure.
Metrology synchrotron radiation station “Cosmos” is functioning in the Siberian Centre of Synchrotron Radiation and uses radiation from the VEPP-4 storage ring. As part of the methodological support of the station's operation, a methodology for measuring the spectral sensitivity of detectors in the VUV range was developed and validated. The calibration is carried out using the reference detector method using a certified silicon photodiode. The report contains a description of the main stages of the procedure, such as obtaining metrologically pure monochromatic radiation, statistical processing of the obtained data, etc.
