switched to parallel cold return
159	Tue Aug 15 15:39:27 2006	Willy Andersson	Quench Recovery	switched to parallel cold return
Return flow temps from solenoid about 40K, TIC121 at about 40K so switching to //cold return. Starting with slightly reduced flow through cold returns, CV145 and CV147 at about 65% open.

38	Thu Jul 29 09:01:11 2004	Doug Preddy	Quench Recovery	switched to parallel cold
Changed to series mode.
10	Wed Apr 21 08:16:18 2004	Doug Preddy	Start Up	switch to series mode
Switched to series mode.
34	Wed Jul 28 07:00:18 2004	Doug Preddy	Quench Recovery	switch to series mode
Switching to series mode. Jumper on vacuum gauge removed.
55	Wed Oct 6 09:25:54 2004	Doug Preddy	Start Up	switch to series mode
switched to series mode
107	Tue Jul 19 16:13:32 2005	Willy Andersson	Quench Recovery	switch to series mode
CR_6KS_M down to 11 K. Switched to series mode. Started small flow to power leads to get them cold. HIC142=0.6 Later open HIC142 wide open. Raised discharge press to 11.4 barA. Letting LHe level build.
144	Fri Jul 21 14:08:04 2006	Doug Preddy	Quench Recovery	switch to series mode
Coils temps <10K.Switching to series mode.
177	Tue Oct 31 05:36:14 2006	Doug Preddy	Quench Recovery	switch to series mode

268	Wed May 27 13:37:22 2009	Doug Preddy	Quench Recovery	switch to series mode
Switched to series mode at ~11:00. Built liquid to 55% by 13:30. Started flow to the power leads.
161	Thu Aug 17 19:45:27 2006	Willy Andersson	Quench Recovery	switch to series cooling
Temps of flow returning from solenoid flat lined at about 10K. Gradually closed CV155. Then switched to series cooling.
