Oven Test
Heater Test
Oven is tested on Mar 24, 2010 without cell. Gas flow is 5~6 in mechanical meter, 508 on digital meter.
- If turn on the constant heater only (set temperature -> 20C), heater temp reached 212C, oven reached 154C
Air Flow meter Calibration @ Mar 9, 2010
Air flow meter in oven control chassis is cross calibrated with mechanical air flow meter at target.
| Mechanical Flow Meter | Digital Flow Meter |
|---|---|
| 1 | 260 |
| 3 | 390 |
| 5 | 490 |
| 7 | 600 |
Alarm 4 is set at 280.
1/4-Wave Plate Calibration
3/15/2010
COMET LASER (JLAB #1)
half power - 12.2 W
I=30A T=20C
| 1/4-Wave Plate | Angle | Residual Power |
|---|---|---|
| #101 | 286° | Reference |
| #102 | 214° | 272 mW |
| #19 | 127° | 256 mW |
| #16 | 330° | 185 mW |
| #21 | 240° | 165 mW |
| #2 | 76° | 55 mW |
| #25 | 120° | 164 mW |
| #20 | 225° | 114 mW |
Also #17 and #7 are identified as half wave plates.
