We will test OM01 (injector service building) sensor for proper read-back and operation today. This will be done with the sensor bypassed at the controller so it will not alarm during this test.

We plan to do a dosimetry swap in the NL tomorrow. If the SL is open, we will swap dosimetry there as well. If not, we'll swap dosimetry in the SL another time. No measurements planned, so ~45 minutes per linac side.
