Abstract
We have built a two-stage adiabatic demagnetization refrigerator (ADR) to o perate cryogenic high-resolution X-ray detectors in synchrotron-based fluor escence applications. The detector is held at the end of a 40 cm cold finge r that extends into a UHV sample chamber. The ADR attains a base temperatur e below 100 mK with about 20 h hold time below 400 mK, and does not require pumping on the liquid He bath. We will discuss cryostat design and perform ance.
