We had hope to explore the phase-space of DRMI and improve the lock acquistion time; however, we did not get very far.
We began with DRMI+arms off resonance under the nominal gaurdian configuration. We acquired the lock 5 times, and found the following acquisition times:
| Lock time (Jan 22, 2015 UTC) | Acquisition Duration | |
| 1 | 00:43:02 | 8 min |
| 2 | 00:49:40 | 3 min |
| 3 | 00:52:53 | 3 min |
| 4 | 00:57:28 | 4.5 min |
| 5 | 01:19:30 | 7 min |
At this point we checked the demod phases for the 1f signal, and decided to adjust the REFL45 phase from 137 deg to 142 deg. We also changed the MICH upper trigger to 5.0 from 10.0. and touched up the alignment (this probably ruins the validaty of our test). With this configuration, we repeated the above and found:
| Lock time (Jan 22, 2015 UTC) | Acquisition Duration | |
| 1 | 02:00:00 | 1.5 min |
| 2 | 02:00:57 | 0.5 min |
| 3 | 02:04:00 | 2 min |
| 4 | 02:05:30 | 10 sec |
| 5 | 02:44:29 | 10 min* |
* flipped CARM offset at one point.
Overall this test was pretty inconclusive, but I thought I would post the lock aquisition times. This evening, we have been running with the MICH upper trigger threshold at 5.0 and it takes about 15 min or so to lock again ...
