Print this reportMagnetic injections at MCBYesterday afternoon we prepared the setup for magnetic injections inside mode cleaner building, that we performed this morning between 08:30 and 10:30. We injected magnetic noise lines between 14 Hz and 140 Hz by sending 0.5 V (1V pkpk) signals lasting 300 sec each to the amplifier connected with the coil (axes orientation W-E) with Onosokky generator. The magnetic activity is monitored with the uniaxial magnetometer already present in the building (N-S: channel to be corrected because currently is set to W-E) and one tri-axial magnetometer (see photos for the locations).
Apparently the injected lines are not visible in Hrec and so We will probably get only an upper limit for the magnetic projection.
