dc.description.abstract	The existing prototype to demonstrate the viability of the Cyclotron Radiation Emission Spectroscopy (CRES) has been upgraded to incorporate tritium compatibility. The spectrum of the conversion electrons from $^{83m}Kr$ has been measured with great linearity and a precision of $2 \ eV$ over the energy range of $17-32 \eV$. The first tritium beta-spectrum using CRES has also been measured to conclude an endpoint value of $E_0 = 18574.1 \pm (17.2)_{stat.} + \left(^{+12.5}_{-21.1}\right)_{sys.} \ eV$. The recorded tritium spectrum is analyzed to set the first CRES limit on the neutrino mass, $m_\beta \ < 146 \ eV \ \ (90\% \ C.L.)$.
