CUORE status and recent crystal validation runs

The Cryogenic Underground Observatory for Rare Events (CUORE) will search for neutrinoless double beta decay in $^{130}$Te at ton$\cdot$year scale. The search sensitivity depends critically on the energy resolution and radio-purity of our bolometric detectors. Recently, we have been working on a series of CUORE crystal validation runs (CCVR's) to measure the energy resolution and contamination of the newly produced TeO$_{2}$ crystals in standard CUORE modules. We also investigated the performances of a new set of neutron transmutation doped germanium thermistors. In this talk, I will summarize the latest CUORE status and results of the recent CCVR's.
