SAMPLE MOUNTING OPTIONS CRYOSTATION Sample mounting is a very important part of successful use of any cryogenic platform. We offer several options to fit different applications. Fixed Sample Mounts • Thermal transfer • Vibration APPLICATION NOTES APP -215 The key issues to consider with your sample are: • Bonding of the sample to the mount • Emissivity • Window proximity The standard Cryostation uses an easily configurable sample mount which is mounted to the cooled platform. This mount and platform are easily accessed once the lid, window assembly, and radiation shields are removed. The sample mount includes a post that can be mounted vertically or horizontally to position the sample near any of the windows. The figure below shows Sample mount orientations • Focusing • Moving the sample several configurations of the internal sample mount for various applications. The sample mount base may be positioned at 45 degree steps with respect to the windows. The post in the sample mount has a flat end plate with four holes which can be used to attach the sample; as shown below. The small hole on the side of the endplate is to attach the sample thermometer.

Both have a sample bonded in the center, with electrical connections made to pins which can mate to connectors. The CB12 version has a central plate where the sample is mounted and wire-bond connected to the pin set. The LCC28 version uses an LCC socket into which a “chip” with sample is inserted. This table provides a comparison of the two styles. APPLICATION NOTES APP -215 TDESM – LCC28 TDESM – CB12 TDESM – CB12 Electrical contacts 12 wires TDESM – LCC28 28 wires Sample bonding Sample bonded to cap plate and wired to board. User replaces plate and board on sample post to change samples. Sample is bonded to leadless chip carrier (LCC) which is inserted into socket for electrical and thermal connection to sample post. Change-out time Changing sample involves disconnecting cables to side pins and unscrewing cap plate from post. Changing sample involves simply removing LCC “chip” and inserting new one. Summary Better thermal connection to the sample. More wires and quicker sample change-out. Piezo Based Mounting Montana Instruments supports piezo based translation of the sample. This may be done from the platform level in the standard system if the series of stages is not too tall. We also offer a “piezo” version with a recessed sample platform to mount a stack of piezo stages in a “pocket”, shown in the image below. This was designed for the Attocube family of stages. These stages are available in X, Y, and Z motion, and also rotation and tilt options. These may generally combined in any order. If you purchase the piezo version, you may also choose to use the standard sample mount without the pocket. For users that want to use the standard sample mount, a raised platform and standard mount are provided. This view shows the location of the standard sample mount in that setup. Piezo Recessed Cryostation with Recessed and Standard Sample Mount Configurations 2 MONTANA INSTRUMENTS CORPORATION www.montanainstruments.com Adjustable Mount The 4100-1162 is an adjustable height sample mount. The overall height is adjustable from 30.7mm to 43.2mm. The post is 11.1mm square in cross section, and has our standard sample mount bolt pattern on top and mounts to an attocube 101 stack on the bottom. The top piece can be switched to a horizontal position to mount the sample off to the side and allow horizontal adjustment. The position of the upper section is held in place by a screw. The holes in the side of the top piece are for mounting a thermometer. 4100-1162 APPLICATION NOTES APP -215 Other Sample Mounts Montana Instruments has a growing collection of sample mounts that we have designed for various applications. These are shown on the following pages along with mounting patterns. This table shows the mount type and image, some information about the interface type, and the overall height. 3 This is intended to simply show the variety of styles available, not to have the user choose the exact size or interface pattern involved. If the user is designing a custom interface, please contact Montana Instruments for help on product use. Drawings of these parts are available for end users.
