Narrative:

I was working final with thunderstorms in the area. I was running aircraft to runway 7R for the visual approach. I had been given an airbus on a downwind about 2 mi south of the field; wbound. I attempted to vector this aircraft for the visual to runway 7R; but his downwind was too close to make it viable. I turned the aircraft north; then back to the east at 7000 ft. Tower called with a go around off runway 19R (another controller was working that final). That controller coordination runway heading; climb to 7000 ft for the go around. The 2 aircraft conflicted just south of las; with the go around sbound. By the time I realized the go around was climbing to 7000 ft; the aircraft were within 3.5 mi of each other. I gave traffic to the aircraft I was working; but by the time we got the go around in sight; the aircraft were 2.68 mi and 700 ft apart.

Title: L30 CTLR EXPERIENCED OPERROR AT APPROX 6000 FT DURING VECTORS FOR RWY 7R AS GAR FROM RWY 19R CONFLICTED.

Narrative: I WAS WORKING FINAL WITH TSTMS IN THE AREA. I WAS RUNNING ACFT TO RWY 7R FOR THE VISUAL APCH. I HAD BEEN GIVEN AN AIRBUS ON A DOWNWIND ABOUT 2 MI S OF THE FIELD; WBOUND. I ATTEMPTED TO VECTOR THIS ACFT FOR THE VISUAL TO RWY 7R; BUT HIS DOWNWIND WAS TOO CLOSE TO MAKE IT VIABLE. I TURNED THE ACFT N; THEN BACK TO THE E AT 7000 FT. TWR CALLED WITH A GAR OFF RWY 19R (ANOTHER CTLR WAS WORKING THAT FINAL). THAT CTLR COORD RWY HDG; CLB TO 7000 FT FOR THE GAR. THE 2 ACFT CONFLICTED JUST S OF LAS; WITH THE GAR SBOUND. BY THE TIME I REALIZED THE GAR WAS CLBING TO 7000 FT; THE ACFT WERE WITHIN 3.5 MI OF EACH OTHER. I GAVE TFC TO THE ACFT I WAS WORKING; BUT BY THE TIME WE GOT THE GAR IN SIGHT; THE ACFT WERE 2.68 MI AND 700 FT APART.
