Virgo Logbook

This morning we have performed some wireless tests on a device that will be used in O4 for the transmission with the baffles to be installed around the IMC end mirror and the end test masses. For this test, this device is placed in the NEB.

We started with a wifi test. We performed some injections at transmission powers of 5, 12 and 20W for periods of 150 and 500 seconds (the specific injection times can be seen in the attached log-file). We saw no effect in DARM.

Then, we proceeded with the Lora tests at powers of 5, 12 and 20W for periods of 200 seconds and varying the transmission frequency between 750-900MHz. Again, we saw no effect in DARM.
