COMMENT ON Upgrade 1L08 to a C75 zone.
Wired the transformer to the diode stack and continued teardown of outgoing control wiring. Measured out new KRRP cables and put in an order for connector pins after realizing the correct size are not on hand or in the stockroom. This is not expected to meaningfully impact the schedule.

Magnet LDRD Measurement Carts in Tunnel
We only finished half of our samples today, and opted to leave our DAQ carts plugged in for tomorrow. They are located in the North LINAC near the NA labyrinth, and must remain plugged in. Please do not disturb, and if you need to let Ryan know (ryanmb@jlab.org).

COMMENT ON SAM2026 - Standing Magnet Degradation Study (LDRD+)
We did half of the samples today (South East corner/stub area).
Tomorrow, we'll hit the West Arc and the North East arc locations.
Our carts have been left in the tunnel (North Linac, plugged in near the NA labyrinth, but in the Linac itself). Please don't disturb.
COMMENT ON Install C-100 style Vacuum Controls and Cable Install NL08 (2026 SAM)
Started populating rack with controls/equipment.
Talked to TJ (VAC) about us pulling cable through our penetration at 1L08, he said that since the cleanroom work between 1L07 and 1L08 is closed up for now and shouldn't be an issue.
Looking at installing cable/smurf this Wednesday 9/30. Any change of date will be communicated.
