Stock Status: In Stock
Delivery Status: 8 weeks


Description

MICA is a cryogen-free multi-pixel TES microcalorimeter spectrometer for applications in X-ray nano- and microanalysis. Cooling is provided by a pulse tube cryocooler mounted on the spectrometer and an adiabatic demagnetization refrigerator (ADR). MICA microcalorimeter EDS superconducting detector array consists of 16 microcalorimeters located at the end of a 25-mm diameter snout. and the spectrometer has been installed on a Hitachi S-4800 FE-SEM for energy dispersive X-ray nano- and microanalysis. An automated control system makes the cryogenics completely transparent to the use
