COMMENT ON Post SAM FE onset measurements C75 and C100 cryomodules
For the purposes of removing DecaRads, the NL can be accessed anytime. Coordinate with RadCon regarding moving from the NL to the SL. Yes, both linacs are to remained locked-up, so the decaRads will have to come out of the North and go back in the South. A full survey of the NL has already been completed.

COMMENT ON Post SAM FE onset measurements C75 and C100 cryomodules
I'll plan to remove the 2 DecaRad systems from 1L24 and 1L25 when the NL is accessible, put them in crates, and then stage them in the NL labyrinth. Unless both linacs are in RA and I can open the arc gate, the above-ground move from NL to SL will require RadCon support.
