- 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

refcav : 0.243
acav : 0.251
