  We report a demonstration of the scalability of optically transparent xenon
in the solid phase for use as a particle detector above a kilogram scale. We
employ a liquid nitrogen cooled cryostat combined with a xenon purification and
chiller system to measure the scintillation light output and electron drift
speed from both the solid and liquid phases of xenon. Scintillation light
output from sealed radioactive sources is measured by a set of high quantum
efficiency photomultiplier tubes suitable for cryogenic applications. We
observed a reduced amount of photons in solid phase compared to that in liquid
phase. We used a conventional time projection chamber system to measure the
electron drift time in a kilogram of solid xenon and observed faster electron
drift speed in the solid phase xenon compared to that in the liquid phase.
