Description
The CAPP-8TB axion dark matter search experiment for the mass range of 6.62 to 7.04 μeV is being performed as one of the CULTASK experiments at IBS/CAPP. The experiment utilizes the cavity haloscope technique introduced by Sikivie with a microwave resonant cavity of 3.5 L volume under 8 T superconducting magnet at a cryogenic temperature of less than 0.1 K. In this poster, details of the experiment configurations are presented including the resonant cavity, cryogenics, magnet, a new locomotive frequency tuning mechanism with a dielectric tuning rod, microwave receiver chain with high-electron mobility transistor amplifiers, data acquisition, control, and monitoring system. The target of this effort is to be sensitive to the QCD axion band with a two-month running time.
