The article discusses the development of a continuously rotating sample device for neutron instruments, aimed at reducing deadtime associated with sample movement. The device, known as the MACS rotator, is mounted on a cryostat and has been tested with a 100g sample cell. The motor logic for the rotator is installed in the NICE control system and is driven by the new even-mode capable VIPER system.
The continuous rotation of the sample allows for optimal data collection and minimizes the deadtime caused by sample movement. The article mentions recent experience with adding a Cryogenic Goniometer to NICE and updating the VIPER motor control system to be compatible with time-stamps, which provides confidence in the swift incorporation of the rotating sample device into the experiment control and data acquisition procedures.
The device is part of the Rotation Stage for 100mm ILL Cryostat, which aims to optimize sample analysis by enabling continuous data collection and sample rotation, ultimately minimizing the deadtime associated with sample movement.
