Fast Sample Exchange System

Cryogenic Measurement System Option

The Fast Sample Exchange (FSE) System is a fully automatic load-lock system for fast sample loading and unloading.

For fast sample exchange, we offer a fully automatic load-lock Bottom-Loading Fast Sample Exchange System. The movement of FSE Insert is computer-controlled and delivers an optimized pre-cooling sequence with a sample cooldown time of typically less than 9 hours.

The load-lock mechanism comes with a smart controller that prevents accidental venting of the vacuum chamber and conflicting operation of the FSE Insert and FSE Gate Valve. The loading mechanism can also be operated manually either via computer software or directly from the FSE Control Unit.

Product Highlights

1.0

Fast Sample Exchange System

Cryogenic Measurement System Option

Fast Turnaround

FSE System enables a fast turnaround by enabling the rapid exchange of samples without warming up the system.

Easy Changing of Samples

With the FSE System, experiments are installed in the sample space located in the FSE Insert. With this method, it is not necessary to remove the radiation shields and vacuum cans from the system when changing samples.

Prepare Samples While Measuring

With multiple FSE Inserts, you can prepare the next sample for experimentation while measuring the current sample in the cryostat.

Protect or Bias Your Sample During Loading and Unloading

There is a grounding wiring option available, which protects the sample while loading the FSE Insert into the system and during unloading. This can also be used to bias your sample during loading and unloading.

Fast Sample Exchange System

Cryogenic Measurement System Option

In the Bottom-Loading FSE System, experimental wiring is located mainly in the cryostat and the wiring is connected to the bottom-loading Sample Holder at the Mixing Chamber Flange.

There is a grounding wiring option available, which protects the sample while loading the FSE Insert into the system.

Available diameters are 48 mm, 58 mm, and 78 mm for both LD and XLD Systems. FSE Insert diameter is determined by the magnet bore if the system has a magnet.

Base temperature and cooling power are measured at the Sample Holder of the FSE Insert. The provided cooldown time is for a typical configuration.

Bottom-Loading FSE System	Guaranteed
Base temperature	< 20 mK
Cooling power at 100 mK	> 50 μW
Cooldown time to base temperature	< 9 hours

Other Faster Turnaround Options

4K Heater

The 4K Heater is a fully automated fast warm-up option, which decreases the warm-up time for our cryogenic measurement systems.

LN2 Pre-Cooling Loop

The Liquid Nitrogen (LN2) Pre-Cooling Loop can be pre-installed in Bluefors systems at the factory to achieve faster cooldown.

Still Heat Pipe

The Still Heat Pipe is a passive component that reduces cooldown time between room temperature and 15 K by 10–15 %.
