In addition to their complete line of laboratory cryogenic equipment, Janis Research offers a wide range of award-winning custom system design capabilities. With in-house computing facilities, computerised designs and manufacturing capabilities, Janis’ experienced physicists and engineers are readily available to discuss your special requirements for any type of cryogenic application
As a worldwide leader in laboratory cryogenics, Janis has developed many custom cryogenic configurations. Many of these have been refined into a standard product line and are available from inventory.
高分辨率磁共振成像的低温恒温器
This cryostat was developed for intraoperative magnetic resonance imaging (MRI) by groups at Columbia University, Duke University, and DuPont. These cryostats are used to cool a set of high temperature superconducting (HTSC) radio-frequency receiver coils located near the patient or object to be imaged.
TSC接收器线圈可以为临床医生产生最高的分辨率图像，但是在用于冷却线圈的低温恒温器上，以保留图像质量。在这里，使用了专门设计的非磁真空尾巴来包围线圈。由于线圈非常靠近真空尾的内壁，因此该材料在疏散下的机械强度对于适当的功能至关重要。尾巴也是半透明的，可为操作员提供视觉上的线圈相对于患者的定位。线圈被热锚定在非金属基材上，并且能够通过低温恒温器顶部的精确操纵器（即，在照片的右侧）进行翻译。由于使用Janis的SuperTran技术，因此低温恒温器也很容易操作。
Superconducting magnet system for use with Rigaku x-ray generator and theta/theta wide-angle goniometer 3TL-STL-XRAY split superconducting magnet
显示的是用于与Rigaku X射线发生器和Theta/Theta广角角仪的超导磁铁系统。将样品放置在高磁场（0至40,000 g）中，其温度可以在2.5至300 K之间变化。可以将样品引入高场区域，并依靠UHV兼容的翻译阶段精确地定位。可以更改样品而不打扰或加热磁铁或包含它的露水。
两个侧面窗户的窗户为样品提供了广角X射线梁路径（以真空的方式行驶），从而可以通过0到38的角度进入传入和衍射的光束。紧凑的设计允许磁铁系统精确地拟合X射线发生器和GONIOMETER的限制。
The complete system includes heaters, field-independent thermometry, an automatic temperature controller, and a superconducting magnet power supply for charging and discharging the magnet. A high-efficiency helium transfer line is also included for continuous cooldown of the sample.
Scanning tunneling microscopy (STM) superconducting magnet system with optical access. Omicron71 superconducting magnet
An 8 T split superconducting magnet system has been designed and built for a scanning tunnelling microscope with optical access to the microscope cooling stage. The microscope is top-loaded into a UHV space that can be baked out to a temperature of 150 °C without affecting the superconducting magnet or the rest of the cryostat. The system offers variable temperatures from below superfluid helium temperatures up to room temperature. Several variations are available on this basic design, enclosing bottom optical access, cryostats for scanning near-field optical microscopes, atomic force microscopes, etc.
