Latest Patents

Theo Ruijl holds a patent for a groundbreaking invention titled "Vibration-free cryogenic cooling." This patent describes an apparatus and methods designed for vibration-free cryogenic cooling, which is suitable for Transmission Electron Microscopy (TEM) and other analytical equipment. The invention features a thermal battery that includes components such as a cryocooler, a thermal switch, a thermal cold storage reservoir, and a cold finger. The thermal reservoir is strategically mounted outside a sample chamber, while the cold finger provides thermal coupling between the reservoir and a sample holder inside the chamber. The system is capable of regulating sample holder and sample temperatures through a heater or an inline variable thermal resistor. The cyclic phased operation allows for cooling the reservoir, decoupling the cryocooler, and enabling temperature-regulated passive vibration-free thermal energy extraction from the sample to the reservoir. This innovative system boasts a stand time of 12 hours at 20 K, showcasing its efficiency and effectiveness.
