Obiettivo
Objectives
The objectives of this project are firstly to investigate detectors, filters and other optical components for use in the ultraviolet with the objective of achieving UV irradiance measurements with an uncertainty of between 0.1% and 1%. Secondly, to establish and compare ultraviolet spectral responsivity scales using new transfer standards, improving base UV scale uncertainties to between 0.1% and 0.3%. Thirdly, to apply the knowledge and techniques developed during the project to improve measurement of solar UV radiation. The final objective is to develop an enhanced intense UV irradiance meter with improved stability for a demanding industrial application capable of achieving an accuracy of 2%.
State of progress
Filter radiometers have been constructed under work package one and are in the process of being calibrated by different NMIs. Candidate transfer standard detectors have been evaluated for sort term stability with the best photodiodes used to build trap detectors for spectral responsivity scale realisation. Synchrotron source based spectral responsivity scale realisation is complete. Many different optical components and detectors have been evaluated for use in an intense UV irradiance meter. Performance of nearly all components tested has been disappointing. Further items are under test
This project was formulated to address the requirement from the European ultraviolet measurement community for higher accuracy UV radiation scales, improved transfer standards for the dissemination of UV scales and for improved instrumentation and methods for the measurement of UV radiation.

Work programme
The project is divided into five work packages. The first work package in the project will target the development and evaluation of new types of ultraviolet filter radiometer for the measurement of the spectral irradiance of ultraviolet sources. Work will also be undertaken to investigate the agreement in UV filter radiometer calibration between different national measurement institutes and for different calibration techniques. The establishment and comparison of ultraviolet spectral responsivity scales based on cryogenic radiometers comprises the second work packages. Three different techniques for establishing UV spectral responsivity scales using cryogenic radiometers will be compared and evaluated. One of the main goals of this part of the work programme is to investigate and select suitable detectors to act as spectral responsivity transfer standards for use in the ultraviolet. Improving the industrial measurement of intense UV irradiance is the subject of the third work package. The objective is to develop and evaluate an intense UV irradiance meter. This device will be used for the measurement of the intense UV sources used for industrial applications such as photolithography of semiconductors. The research and development process will involve the investigation of the stability of components when exposed to intense UV radiation. The fourth work package of the project aims to construct a portable calibrator for solar ultraviolet monitoring spectroradiometers, applying the technology and developments described above. The fifth and final work package is primarily concerned with administration and dissemination of the results of this project to the European UV measurement community. At the end of the second year of this project a workshop will be organised at which the current progress and results from the work programme will be reported.
