The cluster is certainly subject to gravity, but it is precisely
because of that that the cluster is sent up gently and allowed to
fall freely while the atoms interact with photons. The free fall
cancels the effect of gravity. That's why they throw them up and
let them fall.

If it truly "cancelled gravity", it would not be falling at all.
Why don't you get that?
When it falls in freefall is accelerating.
acceleration is a g-force event.
Or do you think when you fall, you do not accelerate at all?

Yes, speaking loosely, acceleration is a g-force event.  So is being
in a gravitational field.  But in this case these two cancel each
other.  That is the point.

Have you ever seen video of astronaut training in which they are in an
airplane that is carefully following a parabolic arc that imitates the
path of a projectile falling freely?  The guys are floating around in
the plane as it there is no gravity.  Note the "as if." Yes, there is
still gravity at work, but there is also the acceleration at work.
And they cancel each other.

So you admit the "atom" in freefall, will not fall inside the clock
that is also in freefall.
:)
Maybe it is you that should think about that.

You have to specify the frame of reference. If the atom is in
freefall and the clock is in freefall, then the atom will not fall
with respect to the clock. Notice the "with respect to the clock"
phrase; the clock defines a frame of reference.

Earth also establishes a frame of reference; the atom still falls
with respect to the earth.

But the point is that according to Einstein, both the gravity of the
earth and the acceleration of the atoms have effects of the rate of
clocks. In the case of free fall, they happen to have equal and
opposite effects on the rate of clocks.
