--obsolete-- DTL Amplifier Lockouts

— filed under: ,

By Mike Hauser, March 29, 2004


During training on the DTL cage last week, I learned from Zheng Ting that when we lock out the DTL amplifiers (e.g., to access the DTL enclosure under the temporary instructions), we should wait at least 15 minutes after we turn off the RF before we turn off their breakers. That is because there is an electric fan inside each amplifier cabinet that cools its power amplifier tube.

Zheng Ting thinks 15 minutes is long enough to allow the PA tubes to cool off.
