Disconnecting the Agilent Cold Probe from the CryoBay
C A U T I O N
Cryogenic Systems Operation
The state will change to Detaching Probe.
3
The CryoBay will purge the helium from the cold loop.
4
When the helium has been purged to a safe level (20 psi
or 0.14 mPa), one of the following windows appears:
•
Okay to Detach Probe
•
Detach Probe Failed. If Detach Probe Failed appears
see
"Error Messages"
5
Click on Ok to close the window
6
The state will change to Idle.
7
The Agilent Cold Probe may be disconnected from the
CryoBay (see
"Disconnecting the Agilent Cold Probe from
the CryoBay"
).
Disconnect the pneumatic line to the Agilent Cold Probe
1
vacuum valve by unscrewing it at the Agilent Cold Probe
vacuum valve.
Remove the flexible vacuum line from the Agilent Cold
2
Probe. Cap the line with a NW25 blanking plate. Click
Vacuum Purge under the advanced section of the
CryoBay controls popup window. See
Probe/Cryogenic System Care When Not in Use"
page 39.
The vacuum clamp is magnetic. Use appropriate care when handling
it around the magnet.
3
Remove the temperature control cable from the Agilent
Cold Probe.
This is a locking connector: when removing the cable,
pull on the connector body.
4
Release the vibration damping pier clamps. Remove the
top of the pier.
Unscrew cryogenic transfer line coupling nut.
5
Separate the CryoBay cryogenic transfer line from the
6
Agilent Cold Probe.
A portion of the He working gas will be vented during
cryogenic transfer line separation. This is normal.
Minimize bending of the flexible cryogenic transfer line
as this may cause internal damage to the line.
