Titolo: | Juice - Majis Experiment-OH Dichroic Radiation Test Report | Autori: | STEFANI, STEFANIA ZAMBELLI, MASSIMO Sergio Fonti |
Data pubblicazione: | 2014 | Numero: | JUI-IAPS-MAJ-RP-009 | Abstract: | The present document reports the test performed on two dichroic filters of MAJIS (Moons And Jupiter Imaging Spectrometer) instrument which is part of JUICE (Jupiter Icy Moons Explorer) ESA mission. The dichroics shall withstand the Jupiter and Jupiter icy moons electron radiation environment without any permanent degradation after mission length Fluence. After a previous test campaign at room temperature on the filters, the radiation tests were performed at the facility DAFNE – Beam Test Facility (BTF) in Rome on 16-22 January 2012, 5-11 March 2012, 9-15 July 2012, 24-30 September 2014 and 30 June-06 July 2014. In order to study the optical performances, using a Fourier Transform InfraRed (FT-IR) spectrometer the transmittance was obtained in the spectral range of interest (from 0.3 to 8 mm), while for the reflectance a Perkin Elmer Lamda has been employed. In order to verify the effect of the radiation test on the optical performances of the dichroics, transmittance and reflectance measurements have been repeated after each test performed @ Dafne. | URI: | http://hdl.handle.net/20.500.12386/34082 | Fulltext: | embargo_20300209 |
