Today, the vacuum pressure inside the Minicav was good : 7.8e-6 mbar
the Gauge model is a Leybold PTR 90N => see picture for details
surprisingly, the same gauge connected to the TurboVac SL 80 was not read with the same value (see pictures)
the Pfeiffer pumping system has its own gauge which gives an expected lower pressure value : 8.94e-7 mbar.

we made a leakage test with the cavity valve closed:
we lost 0.2e-6 mbar in 15s which is roughly equivalent to 1e-3mbar in 20h !!!

we made also a test of locking with the pumping system ON:
the silent block works pretty well and the locking doesn't seem perturbated.
(air flow OFF and no talking during the lock)
we clearly saw a sensitivity of the lock to the laser power => we can think to a feedback loop on the laser power with and AOM for example.
