CDE 7232

The CDE7232 is the first Thales cooler controller designed specifically for bench top use in laboratory or engineering environments. It combines all the features of Thales state-of-the-art linear cooler drive electronics line with an easy to use push button interface.

Properties

  • Supply voltage: 100-240 VAC
  • Output voltage: max. 32 VAC
  • Output current: max. 7 AAC
  • Output frequency: 35-100 Hz
  • Sensor inputs: Pt100 or Diode
  • Options: Active Vibration Reduction

GUI Software

After the successful introduction of the new, DSP-based, Cooler Drive Electronics MPCDE, HPCDE and XPCDE, Thales Cryogenics developed a Graphical User Interface to unlock the full potential of the CDE.

The GUI eliminates the need to learn specific commands yet put easy access to main cooler drive parameters at your fingertips:

  • Monitor the status of the most important variables.
  • Diagnostic tools help you to test and optimize cooler performance.
  • Clear screen graphics and easy printout of the presented data.
  • Simple access using a serial (RS232) port.

Designed to work under Windows  operating systems the GUI presents cool down data of sensor voltage versus time. Data collection extends to multiple days (depending on the hardware used) and a look-up function is available to easily access any sensor data point.
Clicking the cool down plot reveals additional information on AC output voltage and DC input power and current.

In the Expert View, extended control features are accessible. The Slow Start Correction Settings allow to interactively set the parameters governing the profile of the startup curve (ramp-up time, voltage levels of the intermediate plane, dwell time on this level, and ramp-up to final output voltage) by directly dragging the curve to the desired values. The Ambient Temperatures Correction Settings enables to adjust the gain for high and low ambient temperatures.

Three different GUI kits are available:

  • GUI-AC – For use with the CDE7232
  • GUI-DC/1 kit – Includes a passthrough cable, for use with the xxCDE series
  • GUI-DC/2 kit – Includes a breakout cable, for use with the xxCDE series

General information – LPT

The Linear Pulse Tube (LPT) series is based on a thermodynamic working principle that is different from but related to the stirling cycle. In the Pulse Tube cold finger, all mechanical moving parts are eliminated. This technology, combined with the proven design of the ultra reliable flexure bearing compressors as used in our LSF series, has resulted in extremely reliable and miniature cryocoolers with a minimum of vibrations.

Pulse Tube Cryocoolers are specially developed for applications where the object to be cooled is extremely sensitive to vibrations. The absence of moving parts in the pulse tube cold head diminishes the influence of most of the disturbances at the cooler-detector interface. The pulse tube cryocooler produces and sustains a detector operating temperature of 80 K.
The combination of a cold head with no moving parts and the reliable moving magnet flexure bearing compressor guarantees the high reliability of this cooler type.

With its specific characteristics, the LPT cryocoolers are very suitable for applications requiring extremely low levels of induced vibration, acoustic noise, and electromagnetic interference.
Comparable in layout to the “split” configuration Stirling-cycle coolers, the pulse tube cryocooler is a sealed device, with the compressor and cold finger constructed as separate components and connected by a malleable metal transfer line. This configuration enhances the flexibility in system design and helps to isolate the sensitive detector even more from compressor-induced vibration or EMI.

Design Features

  • dual opposed pistons driven by linear motors minimise compressor vibration and acoustic noise
  • compact magnetic circuit optimised for motor efficiency and reduction of electromagnetic interference (EMI).
  • pulse tube cold head with no moving parts suitable to directly mount highly sensitive detectors.
  • moving magnet flexure bearing design eliminates possible causes of performance degradation.
  • no maintenance is required.

General info – LSF

The result of many years of fundamental and experimental research have been condensed into state of the art design of a very reliable miniature Stirling cooler, combining two technical breakthroughs, flexure bearings and moving magnets.

These two breakthroughs have resulted in an extremely reliable cryocooler, without sacrificing other important aspects such as affordability, compactness and weight. Flexure bearings allow for movement of the compressor pistons in axial direction, yet it features very high stiffness in the radial direction thus avoiding contact between piston and cylinder wall. This results in extremely long lifetimes, proven by lifetime tests. In these tests almost all coolers are still running well within specification after at least 20.000 operational hours.

The design of the correct flexure geometry is critical. Dedicated Finite Element Modeling techniques have been used to optimize the design and to ensure that the fatigue stress levels of the material are never exceeded. Mounting of the flexure is performed using a patented assembly procedure. The use of stationary coils and moving magnets has removed several common cryocooler failures. As the coils are placed outside the helium working gas, there is no contamination of the working gas due to potential outgassing and there is no need to use vulnerable hermetic feed throughs. On top of that, the use of moving magnets implies that there are no flying leads between the coil and the stationary world.

Thales Cryogenics LSF-range of coolers has proven to provide excellent performance under extreme conditions, combining a long life operation with affordability. This provides the perfect cooling solution for highly demanding applications such as constant surveillance, space and aircraft. As in the UP-LS series, the LSF coolers can be combined with several free displacer cold fingers, in both closed cold finger design and in dedicated IDCA design, offering the user the ability to choose the right finger in terms of cooling power and mechanical requirements.

The results of many years of fundamental and experimental research have been condensed into the state of the art design of a very reliable miniature Stirling cooler, combining two technical breakthroughs: flexure bearings and moving magnets. These two breakthroughs have resulted in an extremely reliable cryocooler, without sacrificing other important aspects such as affordability, compactness and weight.

In the LSF9508, both these breakthroughs have been applied in a compact-compressor cooler mated with an IDCA-type displacer that will fit in a standard 9 mm bore dewar, making it a suitable drop-in replacement for systems using a detector in a 9 mm dewar, but where the higher reliability of a flexure-bearing cooler is needed.
