CDS maintenace summary

WP7381 Oaf testing prior to ISI common motion upgrade

Dave:

It looks like I've fixed the over-run of h1oaf by moving h1tcscs to fill the core vacated by h1ngn. I'll post details in an alog.

Stopping h1tcscs reminded us of the CO2 laser chiller issue when the setpoint temperature control voltage goes to zero. Fil wired up the chiller summation box which should resolve this issue, but we found that ITMY's water temp increased when h1tcscs was restarted. It had reached 26C when Fil removed the summation box from the control circuit. More details in another alog.

WP7378 OS upgrade for Scientific Linux Machines

Greg:

Greg updated and rebooted the DMT SL7.4 production machines (h1dtm[0,1,3]). He also upgrade h1hwinj2 from 7.3 to 7.4. h1hwinj1 is actually running 6.9 and its upgrade is not simple. We will most probably go ahead and re-install SL on this box next week.
