Subject: new slow actuator values 

- more insulation to the refcav chamber added

actual slow actuator values for both cavities:
refcav : 0.4385
acav : 0.2539

-> ~215MHz difference

with ~6mK/Mhz  -> refcav temp reduced by 1.3K

01/25/10  8am:

refcav temp now 67.7, slow actuator 0.304 -> reduced temp further to 67.5

01/26/10  1pm: 

refcav : 0.243
acav : 0.251

01/27/10  11am

refcav: 0.2456    temp:67.4
acav: 0.2582      temp: 40.0

01/27/10  9 pm

refcav: 0.2423    temp:67.55
acav: 0.2578      temp: 40.0

01/28/10  1am

refcav: 0.2525   temp:67.65
acav: 0.2578      temp: 40.0

01/29/10  4 pm

refcav: 0.2485   temp:67.65
acav: 0.2335      temp: 40.0
