The µSR Spectrometer Inserts:
Cryostats, Ovens, and Pressure cells

Into each spectrometer go a number of sample-containing inserts. Most of these are cryostats, but there are also ovens, pressure vessels, and RF resonance cells. Most have various modes of operation, including different sample holders, sometimes having internal counters. When planning an experiment, you should look at this list to see which combination of spectrometer and insert will provide the experimental conditions desired.
