MCS-EMP temperature options
For electronic material characterization
Temperature options provide fixed or variable temperature sample environments that mount between the poles of the MCS-EMP.
Required for all temperature options
The MSC-EMP variable temperature kit provides the required components to support our full suite of variable temperature options. When you select this option while configuring your platform, your MCS-EMP will include a Lake Shore temperature controller, a thermocouple input card (when purchased for use with the high-temperature oven), GlideLOCK™ alignment system mount, vacuum handling kit, mounting hardware, flanges, hoses, connectors, and accessories. Must be configured as part of the base MCS-EMP platform.
GlideLOCK™ option alignment
GlideLOCK™ room temperature and variable temperature options slide in and out of the MCS-EMP on a precision-aligned tray and click into place to assure repeatable positioning of the enclosed sample within the magnet poles. The MeasureLINK™-MCS software
further simplifies the implementation of the GlideLOCK™ options by automatically detecting and displaying each option as it is plugged into the MCS-EMP. With controllable options, the software provides automated, unattended temperature adjustment
throughout the entire temperature range of that option. The GlideLOCK mechanism is included when the MCS-EMP is configured with the variable temperature kit or can be selected independently if only room temperature measurements are needed. Must be
configured as part of the base MCS-EMP platform.
High-performance temperature options
High-temperature oven (EMP-OVEN with insert)
The oven body and insert with GlideLOCK™ allow you to study the effects on your material as you heat your sample to as hot as 1,273 K*. The oven insert is placed into the top of the oven body and attaches via captive thumbscrews. Because
the oven body and oven insert form a vacuum-tight enclosure, sample heating can be done under an inert gas atmosphere—argon is recommended. The oven insert has a temperature sensor mounted near the sample location to ensure a reliable temperature
measurement feedback loop. One EMP-OVEN-SI insert is included with EMP-OVEN.
The oven single sample insert has 4 prober pins
Requires MCS-EMP with variable temperature kit, E2M vacuum pump or equivalent (compatible with TPS-FRG), Ar or He gas cylinder with regulator and hose barb.
*At 773 K and ±1% rdg: maximum = 1 MΩ; at 1,273 K and ±1% rdg: maximum = 1 kΩ
Closed-cycle refrigerator
Closed-cycle refrigerator (CCR) body and insert (EMP-CCR). CCRs provide a variable temperature cryogenic environment by cooling helium exchange gas. No liquid cryogens are required, so ongoing operating costs are minimal.
In order to optimize efficiency and throughput, your sample is surrounded by helium gas at a pressure slightly above atmosphere, allowing samples to be exchanged without breaking vacuum or warming the CCR. Pump out of the vacuum jacket to 100 Pa
(0.1 Torr) is required prior to cool down. One EMP-CCR-SI insert is included with the EMP-CCR, as well as a stand for mounting.
The CCR single sample insert has a sapphire pad and solder posts
Requires MCS-EMP with variable temperature kit, TPS-FRG vacuum pump or equivalent, LHe gas cylinder and regulator; must specify single-phase (208/230, 200, 220 CE, 240 CE VAC) line voltage at order.
Closed-cycle refrigerator with optical access
CCR with sample top side optical access (EMP-CCR-O). When combined with the sample top side optical access kit and the optical access magnet, the optical access CCR allows you to study the effects that various wavelengths of light may have on your
material samples at cryogenic temperatures.
Vacuum pumps
Used to annually evacuate the cryogen transfer line of the optional cryostat and single stage variable temperature assembly (transfer line and kit are included with these options), the TPS-FRG turbomolecular vacuum pump provides vacuum to 1.33 × 10 -3 Pa (10-6 Torr). In addition to annual cryogen transfer line maintenance, the turbomolecular vacuum pump can also be used to evacuate the cryostat vacuum space. Lake Shore also offers the E2M two-stage rotary vacuum pump with mist filter.
Recirculating chillers
Lake Shore offers recirculating chillers in order to provide a complete laboratory solution. These chillers feature a CFC-free refrigeration system.
The refrigeration system uses a hermetically sealed compressor and hot gas bypass system of temperature control. This system eliminates on/off cycling and premature wear of the compressor. Strong pumps provide continuous flow even through cooling lines with small IDs.
