Chimera – cooling and heater chamber for powder diffraction
Closed-cycle He cryostat for XRD at low to medium-high temperature
The Chimera chamber is a new non-ambient attachment from Oxford Cryosystems and essentially a smaller version of the Phenix Cryostat. It incorporates a single stage Gifford McMahon cooler (as opposed to the two-stage cooler of the Phenix) to enable measurements at temperatures from -203 ºC (70 K) to 252 ºC (525 K) without liquid nitrogen. Chimera offers excellent temperature stability of 0.1 K and variable ramp rates, (1 – 360 K/hour). It takes only 35 minutes to cool down from room temperature to 70 K. Thanks to the design there is virtually no consumption of helium. Sample preparation and exchange are quick and easy.
Currently Chimera is delivered on a case-by-case basis. Please contact your local PANalytical representative for the details.
