Narrative:
At XA30 am, I assumed the radar position. Sectors were combined and no radar associate controller was present. I had 5 aircraft inbound to atl and was spacing those aircraft. I turned the B727 back on course. However, the rate of turn was much less than I anticipated. Additional turns were issued, however separation was lost. I believe that my relative inexperience as a radar controller, combined with the early morning hour, and my fatigue were large contributing factors to this event.

Title: ZID CTLR EXPERIENCED OPERROR AT FL310 DURING RADAR VECTOR PROCS BTWN 2 ACR'S.
Narrative: AT XA30 AM, I ASSUMED THE RADAR POS. SECTORS WERE COMBINED AND NO RADAR ASSOCIATE CTLR WAS PRESENT. I HAD 5 ACFT INBOUND TO ATL AND WAS SPACING THOSE ACFT. I TURNED THE B727 BACK ON COURSE. HOWEVER, THE RATE OF TURN WAS MUCH LESS THAN I ANTICIPATED. ADDITIONAL TURNS WERE ISSUED, HOWEVER SEPARATION WAS LOST. I BELIEVE THAT MY RELATIVE INEXPERIENCE AS A RADAR CTLR, COMBINED WITH THE EARLY MORNING HR, AND MY FATIGUE WERE LARGE CONTRIBUTING FACTORS TO THIS EVENT.
