- 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
