Quantum Design Helium Recycling Case Study:  Institute for Biomagnetism and Biosignal Analysis, University of Münster

"Quantum Design was able to help us become more independent from our helium suppliers and avoid the high prices for liquid helium."

The Institute for Biomagnetism and Biosignal Analysis uses a CTF Magnetoencephalogram (MEG) to carry out neuroimaging and electrophysiology. Their system consumes 95 liters of liquid helium a week and requires three transfers every two weeks. The high cost of liquid helium in Germany and occasional difficulties in obtaining helium from suppliers prompted their desire to gain control of their helium supply by recycling the liquid helium they were already using.

An ATL160 and Back Pressure Controller were installed in a Direct Recovery configuration at the site. The Back Pressure Controller maintains the CTF MEG helium bath at a precise pressure, to ensure the helium recovery equipment does not affect their electrophysiology neuroimaging measurements.

The small size and mobility of the ATL160 works very well with the Institute's space restrictions. Users enjoy the automated, easy operation and high liquefaction rate.

Quantum Design Helium Recycling Case Study:  Florida Hospital for Children

"Easy interface with our MEG, real time monitoring of performance, and ease of helium transfers are our favorite features."

Florida Hospital for Children is using an Elekta MEG system in their Magnetoencephalography Lab. This system consumed 90 liters of liquid helium per week and required a weekly transfer. Rising costs and shortages in their helium deliveries prompted a search for better alternatives for keeping their instrumentation running.

A Quantum Design ATL Helium Recycling System employing an ATL160 and a Back Pressure Controller was chosen because the technology is already equipped to interface seamlessly with their Elekta MEG system.

Since incorporating the ATL technology, they have been very happy with the easy-to-use interface of the ATL160, the real time monitoring of its performance, and the ease of transferring helium from the ATL system to their MEG. They were especially surprised and satisfied with the auto flow adjustment feature which maintains a selected PSI during transfer.

"The main reasons we chose the ATL160 was a combination of low price and support for our MEG system."

The Anschutz Campus uses a 4D Neuroimaging MEG to conduct medical research and training. This system consumes an average of 70 liters of liquid helium per week with cryogen transfers three times every two weeks. Rising costs of liquid helium and the desire to avoid late or "short" deliveries prompted the department to find a more reliable helium solution.

A direct recovery helium recycling system was chosen based on the availability of a Quantum Design manufactured recovery kit and promised support for their 4D MEG system. A back pressure controller was installed to maintain their 4D Neuroimaging MEG's helium bath at a precise pressure.

The ATL recycling system has allowed the researchers to focus on their work rather than worrying about unreliable liquid helium deliveries, ice in their helium, or storage dewars with leaking valves. In addition to the practical motivations, users stated saving a finite resource was very important in their decision making.

Medical FAQs

How do I know which components I need to recycle helium from my cryostats?

Our sales associates are experts in determining the ideal recycling system for your instruments based on helium and transfer needs, space constraints, and the instruments to be connected. All of these details will be explained clearly in the Planning Stage of discussions. In cases where there might be facility requirements for installation, our trained staff can work directly with you and your facilities team to provide all necessary information for optimal deployment.

Does Quantum Design offer a recovery kit for my instrument?

Quantum Design offers recovery kits for the majority of MEGs on the market and offers generic recovery kits which can be adapted to most instruments. With our extensive experience recovering from many instruments, we can consult on how to best connect your instrument to a Quantum Design helium recycling system. Recovery kits for specific instruments will be installed by our technicians at time of installation.

Will helium recycling affect my measurements?

Helium recycling should have zero effect on your measurements. Great care has been taken in the design of the recovery kits to avoid affecting measurements. All MEG recovery kits incorporate a waveguide in the magnetically shielded room (MSR) penetration, and non-magnetic materials are used on the components installed inside the MSR. The pressure in the recovery piping is typically constant, within 30 millibars. Systems especially sensitive to pressure changes should have a Back Pressure Controller (BPC) installed which will automatically compensate for these slight pressure changes and maintain the instrument's pressure with fluctuations less than 3 millibars.

How difficult is it to operate and maintain a helium recycling system?

All Quantum Design helium recycling systems are designed to be operated by any user with little to no previous experience in cryogenics. Touchscreen interfaces and intuitive menus make the equipment easy to learn. At the time of installation, a Quantum Design Technician will instruct users on the operation of the equipment. Resources and documentation are available to users on the Pharos online database. Follow-up training can be scheduled for new users.
