The High Resolution Dynamics Limb Sounder (HIRDLS) will undergo Test and Calibration
at the University of Oxford in a 2 metre diameter by 4 metre long thermal
vacuum chamber located in a Class 1000 cleanroom. Multiple ports accommodate
the many vacuum feedthroughs required to route essential services to the space
instrument and its test equipment. The photograph shows two of the ports configured
for electrical connections which utilise Holifield supplied panels.
