| Continuum | The infrared microscope on Beamline 1.4.4 is a Thermo Scientific Continuum XL. |
| cryostat | A cryostat is used to cool a sample to below room temperature, and typically to cryogenic temperatures such as liquid nitrogen (77K), liquid helium (4.2k), or even lower. The infrared beamlines have several cryostats available to users. |
| cycle | The ALS runs in beamtime cycles, typically 6 months long, and typically January - June, and July - December of each calendar year. Users must apply for beamtime for each cycle, or renew an active beamtime proposal for the next cycle. |
