当系统正确安装在墙壁和工作台上并进行适当调整后，压缩机工作时产生的振动影响非常小（几乎可以忽略不计）。

加宽（不是扩大！）完全可复制，远低于2%。这种加宽实际上没有任何影响，几乎在所有情况下都可以忽略。但是，比较林宽度的时候需要用同样计算方式！

Displex系统实际上是无振动的！

穆斯堡尔谱配置

为了最大限度地隔离振动，系统的正确安装是非常重要的。ARS提供了一个特殊的超低振动支架用于隔离超低振动恒温器来自冷头和地板的振动。

该支架可以通过调节到恰当的高度来支撑冷头。

低温恒温器安装在低振动平台上。它由一个高质量的花岗岩块（用户提供）组成，由4气腿支撑（可选ARS产品）。额外的弹性隔震器过滤掉从地板到低温恒温器的振动。

系统可通过关闭制冷机来观察振动对实验的影响来进行测试。

CS204PF/800K-DMX-20

This ARS system is being used for basic optical characterization experiments (absorption, reflection and photoluminescence spectra), as well as magneto-optical characterization and time-resolved ultrafast laser spectroscopy.

CS204-DMX-20 - NARROW GAP

This cryostat was sold to Prof. Shannon Yee of the Georgia  Institute of Technology. It will be used for applications which focus on heat  transfer in combustion and energy systems. The cryostat's wide operating temperature range allows the user to characterize thermoelectric performance  across a range of 4 K to 800 K, and perform magneto-optical Kerr effect (MOKE)  experiments. It was designed to have low vibration levels at the sample and to  integrate with a narrow gap electromagnet.

The cryostat includes the following special features:

• A custom-designed narrow gap vacuum shroud that integrates with the ultra-low-vibration interface (DMX-20).

• A narrow gap vacuum shroud, machined from aluminum, which integrates seamlessly with the narrow gap environment of electromagnet pole pieces. (Pictured, top left.)

• An 800 K high-temperature interface at the tip, with electrical feedthroughs thermally anchored on the cryocooler’s first and second stages. (Pictured, top right.)

• Instrumentation for accurate temperature control across the range 4 K to 800 K, in the form of a Cernox sensor and cartridge heater.

• A gold-plated radiation shield. This is the optimal choice for shielding your sample and achieving the lowest base temperatures.

• Electrical feedthroughs which provide access for characterizing the sample’s resistivity and thermoelectric performance as a function of temperature.
