Some thoughts on the gravitational interaction of antimatter

The gravitational interaction of antimatter has not been observable leaving the possibility that repulsive force can explain the expanding universe.

CERN tried a few years ago to weight antihydrogen to determine if the
gravitational attraction is repulsive or attractive.  They did not have the
accuracy, sufficient material and time nor likely money.  My understanding
is that the antimatter is trapped (taken) from a beam and stored to where it
can be accumulated. 

I recall that gravitational force behaves similar to electromagnetism.  An electron moving in a magnetic field is forced to move at a right angle to the field.  Similarly, matter moving through a gravitational field is also force (earth circles the sun for example)

Question:  Cannot the gravitational attraction be observed by comparing two beams of antimatter?
One clockwise in the CERN tube, the other counter-clockwise, both beams moving at high speed through the Earths gravitation field but with a different right angle force..  There should be a noticeable difference in deflection of the two beams and it would not be necessary to accumulate enough of the antihydrogen to do a "weighing".

I asked this question over at "ask a physicist" and got the following answer quote:

I can't consider a question with no reference to the primary references. I
never heard of this experiment.
