Procedure
I was cleared to taxi from via Taxiway A to Runway XXR in my [Homebuilt Experimental] tailwheel aircraft. A Challenger 300 had been cleared from the West Ramp to hold at Taxiway A1; while waiting to cross XXR to get to XXL for departure. Just as I was taxiing directly behind [the Challenger 300]; Ground cleared him to cross XXR.  [The Challenger 300] applied immediate power to taxi. I was directly behind him; I tried to accelerate but was unable to get past his jet blast before we were blown in a violent 330 - 360 degree right ground loop. My aircraft suffered damage to the left wing tip; both wheel fairings; and the left gear fairing. There was no prop strike and no contact with any flight controls. Neither I nor my passenger was injured.  The cause of the problem was the Ground Controller not noting my position directly behind [the Challenger 300] when he cleared him to cross; I also believe [the Challenger 300] used excess power to begin his taxi roll.
Pilot of an amateur-built experimental aircraft taxiing behind a Challenger 300; experienced a ground loop due to jet blast when the jet powered up to resume taxi. Experimental aircraft suffered limited damage to wing tip and wheel fairings.
