Narrative:

I had 4 TCAS/ traffic alerts in a 20 minute period from aircraft departing off of 5c1 and one VFR that flew through my final.number 1 aircraft X; VFR 1200 code was at 036 descending from north to south across sat final headed to 8t8; aircraft X was a on base turn to sat descending out of 040 to 030. Traffic issued; closest proximity 1 mile 1/2 and 300 feet.number 2 aircraft Y was on a base turn to sat at 040; VFR 1200 code off of 5c1 climbed right into aircraft Y on base; closest proximity; merged and 600 feet; traffic issued.number 3 aircraft Z was on a turn to final descending to 030. VFR 1200 code departing 5c1 climbed right into final with aircraft Z; aircraft Z was stopped at 035; traffic alert issued; closest proximity; merged and 400 feet.number 4 aircraft a was level flight at 060 on the downwind for sat. VFR 1200 code departed 5c1 and climbed through sat final and north downwind towards aircraft a. Traffic issued; closest proximity 1/2 mile and 800 feet.all of these 1200 code aircraft never called approach to receive service; they stayed 1200 in a very critical part of sat airspace.the amount of gliders and VFR 1200 codes that routinely fly through our final; base; and downwind is alarming. Sat needs an airspace change to either extend the class C; or go to class B airspace to protect our final on all flows. Our final is not protected; I am a member the local safety council at sat; we have talked to 5c1; and many of the VFR pilots in the area numerous times. The talks are not enough; the VFR 1200 code aircraft continue to compromise safety and something needs to be done before there is a major accident. These examples above happened within 20 minutes of single session I worked today; this is unacceptable. Something tragic will happen if we do not step up and do something about this safety issue; sending us to talk to these pilots and schools is not fixing the problem.
