HAYSTAC (Haloscope at Yale Sensitive To Axion CDM) is one of the leading searches for axionic dark matter in the world. Our experiment utilizes cutting edge technology in the fields of quantum electronics, cryogenics, and electromagnetics to explore regions of parameter space have long been out of reach. Each day we work towards solving some of the greatest mysteries in modern physics. Read more about the science of axionic dark matter and the technology that makes our experiment possible.
