CUTTAIA, FRANCESCOFRANCESCOCUTTAIA2024-06-202024-06-202008http://hdl.handle.net/20.500.12386/35202The quick look analysis of POST TV WFT AMB 01 ( performed in Liege, CSL, on August 2008) showed some possible non ideal behaviour of LFI 18 S2. In particular, a non clear separation of sky and ref signal was observed under certain conditions. Objective of this note is to perform a deeper analysis of the LFI 18 S2 behaviour, comparing between results found during different tests: PRE and POST TV, Warm Functional Test in Cannes ( August 2007) , CRYO 01 performed in Liege. The aim is to investigate a possible problem related with the PH/SW correct functionality in RCA 18 . In the case that any problems or unclear behaviour are found, results from this work will be used to prepare an extra test able to finally clarify the residual problems.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
