Narrative:

Mht radar failed for approximately 30 seconds. At the time I had 3 aircraft at 10000' and 3 aircraft at 8000' in the same general area. I was using minimum radar sep to mix 3 departures with 3 overflts (min sep = diverging courses rule). The supervisor on duty released the radar to maintenance west/O notifying or asking either radar position (there were 2 sectors in use at the time).
