| Date | Description | Comments |
|---|---|---|
| 12/14/2015 | Pictures | Documentation of crystal's conditions as it arrived at CUA. |
| 01/28/2016 | Thermal annealing | Ramp up at 18oC/hour up to 200oC. Stays for 10 hours and ramp down at 18oC/hour. |
| 03/02/2016 | Light Yield | Run 3148: crystal wrapped with ~5 layers of teflon tape and 2 layers of black tape. Steps of 20min, 1cm. T=18oC. LY = 19.61 pe/MeV. |
| 03/04/2016 | Transverse Transmittance | At the center of the crystal, every nm from 200nm until 800nm. Sample: 1309 |
| 03/04/2016 | Dimensions | Crystal's dimensions measured. Length and six points of width (3 in each face). |
| 05/23/2016 | Transverse Transmittance Scan | Wavelengths: 360nm, 420nm, 620nm. Sampling period: 0.6s, moving motor at 2mm/s. |
| 07/11/2016 | Longitudinal Transmittance Scan | Wavelengths: 200-800nm. Sampling period: 0.6s, moving motor at 2mm/s. |
| 07/26/2016 | Xray Radiation | 70 minutes, 160mV, 6mA. ___ mm from beam origin. |
| 07/26/2016 | Transverse Transmittance Scan | Wavelengths: 200-800 nm. 10cm down. |
| 07/26/2016 | LED curing | 34 LEDs, 3.5 V for 7 minutes. |
| 07/26/2016 | Transverse Transmittance Scan | Wavelengths: 200-800 nm. 10cm down. |
| 08/01/2016 | Transverse Transmittance Scan | Wavelengths: 200-800 nm. 10cm down. Crystal was most likely cured and preIR trans baseline was determined (wasn't done originally). |
