SICCA 07

Date	Experimenter(s)	Description	Comments
01/10/2016	Salina	Pictures	Documentation as arrived at CUA (received from Caltech). Name of the crystal was observed scratched on the face. Pictures 01/10/2016.
01/14/2016	Marco	Long. Transmittance	Crystal unwrapped.
01/14/2016	Marco	Transverse Transmittance	Spectral measurement.
06/01/2016	Marco	Longitudinal Transmittance	Spectral measurement, Lambda 950 (integrating sphere). Wrapped crystal.
06/02/2016	Marco	Longitudinal Transmittance	Repeating measurement, to make sure alignment and other effects are indeed negligible in our setup.
06/03/2016	Marco	Thermal annealing	Ramp up at 18oC/hour up to 200oC. Stays for 10 hours and ramp down at 18oC/hour.
06/06/2016	Marco	Transverse Transmittance	Spectral measurement with Lambda 750.
06/06/2016	Marco	Transverse Transmittance	Spectral measurement with Lambda 950 - integrated sphere (may not be at exactly the same position).
06/06/2016	Marco	Crystal wrapped	5 layers of teflon tape and 2 layers of black electrical tape.
06/06/2016	Marco	Longitudinal Transmittance	Spectral measurement with Lambda 950 - integrated sphere.

Transmittance measurements

Longitudinal transmittance

Longitudinal transmittance measured at Lambda 750 (no integrating sphere). Crystal as arrived at CUA (probably irradiated at Caltech).

Longitudinal transmittance measured at Lambda 950 (with integrating sphere).
