  The Cornell ERL 7-cell cavities for the Main Linac Cryomodule (MLC), six 7-cells in total- have been fabricated, processed, and tested in the Cornell Laboratory for Accelerator-based Sciences and Education (CLASSE) vertical test pit. All have surpassed the specification values (Eacc=16.2MV/m with Qo of 2.0·1010 at 1.8K). In fact, the achieved Qo during vertical test were much higher than specs, the average of Qo is almost 3·1010 at 1.8K. In this poster, we will describe about our ERL cavity fabrication, preparation, and vertical testing results.
