Title: | Juice - Majis Experiment - JSIR and MIRL emitters report test | Authors: | STEFANI, STEFANIA BIONDI, David BOCCACCINI, Angelo |
Issue Date: | 2018 | Number: | JUI-IAPS-MAJ-RP-00910 | Abstract: | The present document reports the tests performed on two IR emitters, JSIR and MIRL respectively, representative of the calibration unit of the MAJIS (Moons And Jupiter Imaging Spectrometer) instrument which is part of JUICE (Jupiter Icy Moons Explorer) ESA mission. In order to verify the performance at different currents in the spectral range 1-6 mm, the radiance has been acquired using two different experimental set up. The first consists of a FT-IR spectrometer which works from 1 up to 14 mm with a variable resolution from 0.01 to 10 cm-1. For the scope of these tests, a resolution of 4 cm-1 has been set. The second set up consists of cryostat with a vacuum chamber that reach pressions af about 10-6 mbar and with a two stage cryo-cooler with a cooling capacity of 50/40W at 43K and 1.0 W at 4.2K. The system has been alligned with a Field-Spec which works from 0.3 to 2.5 mm. In this last case, the spectral range is different by the working conditions of the IR emitter but this configuration allowed compare the efficiency of the sources both air and vacuum conditions. | URI: | http://hdl.handle.net/20.500.12386/34081 | Fulltext: | embargo_20370131 |
