Time LOG

CRYTUR 01
Date Experimenter(s) Description Comments
xx/xx/2015 Marco Wrapped Preparing for light yield measurement. Approximately 5 layers of teflon tape, and 2 layers of black tape.
xx/xx/2015 Marco LY scan ...
12/14/2015 Marco unwrapped Preparing for annealing.
12/14/2015 Marco Thermal annealing Starting 11:00AM. Ramp up at 18oC/hour until 200oC, stay at 200oC for 10 hours, ramp down at -18oC/hour.
12/17/2015 Marco Longitudinal Transmittance After annealing.
07/15/2016 Summer Students Longitudinal Transmittance Wavelength:200-800nm.
08/11/2016 Summer Students LY scan RUN:3411. Motor was lowered to approximately 5 cm down crystal. ~18oC. LY: 11.986 phe/MeV
11/29/2016 Salina Light Yield Run 3432: ~100K events; crystal wrapped with ~5 layers of teflon tape and 2 layers of black electrical tape. Steps of 20min, 1cm. T=18°C. LY = 8.23 ± 1.08 pe/MeV. Not enough statistics? Need to re-run with more stats (see pictures below)

Transmittance measurements

Longitudinal transmittance measured at Lambda 750 (no integrating sphere).
