Agenda and Notes

1. Operations

LINAC

Normal

C100 heaters are in independent mode. We have been working with Arne to lower the North LINAC pressure following a test plan. We have moved in two 0.0005 steps. We are now at 0.038atm. CC4 has slowed by 20 HZ to ~540HZ.

CHL1

Normal

CHL2

Normal

ESR

Hall C believes the high SHMS back pressure is because of the flexible anaconda. Hall C changed the anaconda but it did not help. Transferline flow has been redirected from dewar to Hall supply to shore up 3atm pressure. More tuning for this mode is needed.

CTF

The CTF shutdown is underway.

HDR

Normal.

2. Projects

Shutdown is underway.

UITF

Thermosiphon is being fabricated.
