"My Studies of the High Field Q-Slope at Cornell University and Current SRF Research at LANL"

Grigory V. Eremeev




One of the current research areas in the field of high-gradient (SRF) cavities is the high field Q-slope. Though the empirical solution of this problem is known - elctropolishing with mild temperature baking - the full understanding of the losses at high fields is still missing. As part of my graduate studies I focused on elucidating different aspects of this problem and carried out a number of studies with the current thermometry system at Cornell University. I will be presenting some of our findings.


After graduation I joined SRF group at Los Alamos that was in the process of commissioning their recently-developed 9-cell 1.3 GHz thermometry system. We successfully tested a nine-cell cavity manufactured by Advanced Energy Systems and identified lossy regions with the new 9-cell thermometry system. I will be presenting these results along with the current progress with 805 MHz cavities.
