| Summary:

Micro-X is a NASA-funded, sounding rocket-borne X-ray imaging spectrometer
that will allow high precision measurements of velocity structure, ionization
state and elemental composition of extended astrophysical systems. One of the
biggest challenges in payload design is to maintain the temperature of the
detectors during launch. There are several vibration damping stages to prevent
energy transmission from the rocket skin to the detector stage, which causes
heating during launch. Each stage should be more rigid than the outer stages to
achieve vibrational isolation. We describe a major design effort to tune the
resonance frequencies of these vibration isolation stages to reduce heating
problems prior to the projected launch in the summer of 2014.
