We examine the discovery potential for SUSY new physics at a p(p) over bar
collider upgrade of Tevatron with roots = 5.4 TeV and luminosity L similar
or equal to 4 x 10(32) cm(-2) s(-1) (the Tripler). We consider the reach fo
r gluinos ((g) over tilde) and squarks ((q) over tilde) using the experimen
tal signatures with large missing transverse energy (E-T) of jets + E-T and
1 l + jets + E-T (where l is an electron or muon) within the framework of
minimal supergravity. The Tripler's strongest reach for the gluino is 1060
GeV for the jets + E-T channel and 1140 GeV for the re + jets + E-T channel
for 30 fb(-1) of integrated luminosity (approximately two years running ti
me). This is to be compared with the Tevatron where the reach is 440 (460)
GeV in the jets + E-T channel for 15 (30) fb(-1) of integrated luminosity.
