A dedicated set of focal plane detectors was built for the magnetic spectrograph Big Karl and was used for identification and four momentum measurement of the $^7$Be. A differential cross section of $\\frac{d\\sigma}{d\\Omega}=(0.69\\pm{0.20}\\text{(stat.)}\\pm 0.20\\text{(syst.)})\\text{nb/sr}$ for the ground state plus the 1/2$^-$ was measured.
