  In the scenario recently proposed by Arkani and Dimopoulos, the
supersymmetric scalar particles are all very heavy, at least of the order of
$10^9$ GeV but the gauginos, higgsinos, and one of the neutral Higgs bosons
remain under a TeV. The most distinct signature is the metastable gluino.
However, the detection of metastable gluino depends crucially on the spectrum
of hadrons that it fragments into. Instead, here we propose another unambiguous
signature by forming the gluino-gluino bound state, gluinonium, which will then
annihilate into $t\bar t$ and $b\bar b$ pairs. We study the sensitivity of such
signatures at the LHC.
