D0 is a collider detector. It will be operating and doing physics at the same time as CDP, therefore it has been decided to train CDP operators to operate and respond to the D0 cryogenic control system. A cryogenic operator will be required to be in residence at D0, during the cooldown and liquid Argon fill of any of the calorimeters. The cryogenic system at D0 is designed to be unmanned during steady state operation. CDP operations has 2 man cryogenic shifts 24 hours a day. It is intended that CDP operators monitor the D0 cryogenic systems, evaluate and respond to alarms, and notify a D0 cryo expert in the event of an unusual problem. A D0 cryogenic system view node has been installed at CDP to help facilitate these goals. It should be noted that even though the CDP view node is a fully operational node it is intended that it be more of an information node and is therefore password protected. The D0 cryo experts may reassess the use of the CDP node at a later date based on experience and operating needs. This engineering note outlines the format of the training and testing given to the CDP operators to make them qualified D0 operators
