Narrative:

While working north radar at the fresno TRACON I took a handoff on small aircraft Y 10 mi south of the czq VOR, nwbnd on V23 level at 10000'. 2 mins later I took a handoff on commuter X 20 mi west of the czq VOR at 16000' descending to 11000'. I was talking to numerous aircraft at the time and vectoring several to the final approach course. I neglected to notice when Y's beacon tag dropped off the screen, when he crossed the main bang. I descended X to 7000' I scanned the display and observed that X was descending from 10700' and 4 mi west of small aircraft Y heading directly at him. I turned X right to a heading of 180 degrees, and Y right to a heading of 360 degrees. The aircraft passed within 3 mi and less than 1000' of each other. Contributing factors: lack of a qualified data person to assist at north radar. Inundated with numerous aircraft during the rush hour. Lack of an MSAW device on the equipment now in use.

Title: LESS THAN STANDARD SEPARATION BETWEEN COMMUTER AND SMA. OPERATIONAL ERROR.

Narrative: WHILE WORKING N RADAR AT THE FRESNO TRACON I TOOK A HDOF ON SMA Y 10 MI S OF THE CZQ VOR, NWBND ON V23 LEVEL AT 10000'. 2 MINS LATER I TOOK A HDOF ON COMMUTER X 20 MI W OF THE CZQ VOR AT 16000' DSNDING TO 11000'. I WAS TALKING TO NUMEROUS ACFT AT THE TIME AND VECTORING SEVERAL TO THE FINAL APCH COURSE. I NEGLECTED TO NOTICE WHEN Y'S BEACON TAG DROPPED OFF THE SCREEN, WHEN HE CROSSED THE MAIN BANG. I DSNDED X TO 7000' I SCANNED THE DISPLAY AND OBSERVED THAT X WAS DSNDING FROM 10700' AND 4 MI W OF SMA Y HDG DIRECTLY AT HIM. I TURNED X RIGHT TO A HDG OF 180 DEGS, AND Y RIGHT TO A HDG OF 360 DEGS. THE ACFT PASSED WITHIN 3 MI AND LESS THAN 1000' OF EACH OTHER. CONTRIBUTING FACTORS: LACK OF A QUALIFIED DATA PERSON TO ASSIST AT N RADAR. INUNDATED WITH NUMEROUS ACFT DURING THE RUSH HOUR. LACK OF AN MSAW DEVICE ON THE EQUIP NOW IN USE.
