We offer an improved vibration isolation for experiments that are particularly sensitive to low frequency vibrations (< 1 kHz).
- Basic vibration isolation frame
- Active vibration damping
- GHS isolation frame
We offer direct optical access to the sample space. The optical ports can be equipped with different window materials and are available in different sizes and configurations. With four 0.5″ optical ports, equipped with our standard fused silica windows, our DR systems still reach a base temperature of <15 mK.
Additional Radiation Shields
We offer the possibility for additional EM shielding around the sample space. These shields can be attached to the mixing chamber plate (LD and XLD) and the cold plate (XLD). Standard shields are made from gold-plated copper. Other materials and platings are available upon request.
Long-Life Cold Trap
We have developed a unique long-life cold trap that allows for continuous operation of the system for up to three years. The trap is integrated with the system and does not need any cryogenic liquids to operate (care-free).
4K Heater Kit
Fully automated fast warm-up option, which allows a day-long warm-up for a standard XLD system.
LN2 Pre-cooling Loop
Engaging LN2 pre-cooling loop with an external source of liquid nitrogen allows to reduce the cool-down time by ~ 40% in case of a basic system.
Extractable 4K plate
The extractable X4K plate is an option for our XLD size dilution refrigerator systems, and it is located between the 50K and 4K flanges. It is designed for the most demanding measurements where large amount of heat needs to be dissipated at 4K stage without interrupting the performance of the system. The extractable 4K plate is not in thermal contact with the rest of the system so even the large heat loads will not affect the dilution refrigerator system performance. The extractable X4K plate is connected to the 2nd stage of one of the dedicated pulse tube cold heads.
