|---|---|---|---|
| 12/14/2015 | Marco | Pictures | Documentation of crystal's conditions as it arrived at CUA. |
| 12/14/2015 | Marco | Wrapped | Preparing for light yield measurement. Approximately 5 layers of teflon tape, and 2 layers of black tape. |
| 12/17/2015 | Marco | Long. Transmittance | Note: not annealed, crystal wrapped. |
| 01/08/2016 | Marco | LY scan | LY measurement with window width of 100ns, at 18oC (see run 3100). LY = 24.28 pe/MeV. |
| 02/01/2016 | Marco | Thermal annealing | Ramp up at 18oC/hour up to 200oC. Stays for 10 hours and ramp down at 18oC/hour. |
| 03/04/2016 | Marco | Transverse Transmittance | At the center of the crystal, every nm from 200nm until 800nm. Sample: 1316 |
| 03/04/2016 | Marco | Dimensions | Crystal's dimensions measured. Length and six points of width (3 in each face). |
| 05/23/2016 | Marco | Transverse Transmittance Scan | Wavelengths: 360nm, 420nm, 620nm. Sampling period: 0.6s, moving motor at 2mm/s. |
| 05/23/2016 | Marco | Irradiation | Placed at Co-60 setup at 4:05PM, around 1cm from source (~95mGy/h). |
| 12/20/2016 | TH | Light Yield | run 3506: 25.94 pe/MeV. Note: not a good fit to SEP and signal with the nominal analysis code and without adjusting fit limits - this needs to be re-done carefully. |
| 01/06/2017 | Rich/TH | Irradiation X-ray | 160 kV, 6.2mA, 30 min. Absorption coefficient at 400nm: 1.58 m-1 |
