Scisat Test Readiness Review Ground Support Equipment Status University of Toronto 29 January 2003
GSE Components • TVAC system (includes LN2 shroud and LHe target) • Collimator system (includes 3 sources to simulate sunlight to test Scisat in TVAC) • Laser Assembly • QI - Spectralon Assembly • Solar Simulator • EGSE
TVAC system status • Good pumpdown performance during MAESTRO baseline tests • Temperature and Pressure monitoring systems work fine • LN2 shroud tested successfully • He target tested successfully • Baseplate handling system tested successfully • New thermal bath to be implemented ? • Gate valve is currntly under repair • BaF2 and ZnSe windows have never been tested with the tank
Collimator System (Not shown: Attenuator Wheel , 3000K blackbody, QI lamp)
Collimator System Status • Alignment system complete, works fine • Xe & QI configurations tested with MAESTRO during baseline tests (Oct 2002) • NO2 handling process in place and tested • Succesful gas absorption measurements taken during baseline tests. • Ozone cell remains untested with collimator system • Cell temperature and pressure monitoring to be implemented • FTS gas cell not tested • 3000K black body not tested • Nitrogen purge tent not finished • Hybrid attenuators for FTS testing not built yet • Polarizers not tested with MAESTRO
Integrated laser platform status • 4 beam expanded lasers (325nm, 532nm, 670nm and 830nm) are combined using a holographic grating • Laser platform has been assembled & partially tested during MAESTRO baseline tests • Laser assembly needs to be re-aligned and tested with MAESTRO
QI - Spectralon calibration jig • This unit has been used many times by MSC for absolute radiance calibration • A new current control algorithm is part of the EGSE & has been used successfully
Solar simulator • Was used for MOPITT characterization, the plan is to use it for FTS imager field tests • All parts seem to be present, but it hasn't been used in several years
EGSE Status • EGSE was successfully used for MAESTRO baseline testing (MAESTRO controller , OGSE controller and TVAC Interface PC's) • PC Anywhere has been installed on all PC's • Some scripts need to be revised • UDP interface with FTS EGSE has not yet been tested • Sending scripts to MAESTRO and FTS simultaneously has not been tested
