Paul Mc Donald (1947-2020)

Announcements | December 21st, 2020

I am sad to report that Paul Mc Donald died of cancer, aged 73, on Saturday 1 st August 2020, at his home in Ramsey, Hants.
As Director of the Cryogenic Industrial Advisory Unit, Institute of Cryogenics, University of Southampton, he was an incredibly popular teacher of post-graduates, and simultaneously a wide ranging research engineer of cryogenics, able to provide reliable answers to many low temperature problems.
During his 50 years working period, 1970 to 2020, Paul made many major contributions to Cryogenics and Cryogenic Engineering.
These contributions have revolutionised cryogenics from 10 cm diameter laboratory cryostats of 1970 to the monster 30 to 50 metre diameter storage tanks and the shipping of bulk cryogenic liquids in 2020 for industry, medicine and Space.
Following his Masters' degree in Cryogenics from the University of Lancaster, Paul joined Oxford Instruments in 1970, designing and installing low temperature cryogenic equipment around the world. By 1980, he was in the team that designed and built the first 500 MHz NMR superconducting magnet system. This provided an immediate contribution towards the first prototype MRI system, cooled by liquid helium, and requiring a refill of liquid every 100 days. For this invention and its medical importance, Oxford Instruments gained a Queen's Award for Technological Achievement, which Paul and two colleagues received from the Queen at a Palace reception. At the same time, Paul was working on the development of the first Continuous Flow Cryostat, which relied on his invention of a sintered copper heat exchanger and consequently avoided the100 day refill problem experienced in a hospital environment.
Cryocoolers with 'dry' helium cooling were not available until much later.
In 1979, the University of Southampton decided to set up the Institute of Cryogenics as a separate teaching and research department. Almost immediately, the Institute was overwhelmed by the industrial problems being met and required many research projects to be set up. At the same time a variety of teaching and training courses were being requested.
In 1982, Paul was recruited from Oxford Instruments and appointed Research Director of the Cryogenic Industrial Advisory Unit within the Institute.
The first success of Paul soon after his arrival was the recognition of the reliable and rugged performance of calibrated silicon diode thermometers, over the whole range of cryogenic temperatures from ambient at 273K to liquid helium at 1 K. A local Southampton firm was then persuaded to build silicon diode thermometers in a capsule for general use in cryogenics. The associated simple and reliable temperature measurements led to the sale of many such thermometers around the world, including NASA space rockets up to the present day. Their accuracy also led to a great deal of cryogenic fluid dynamics findings on low temperature fluids and their extraordinary high heat transfer properties down to 1 K.
Paul's success with accurate thermometers led to the 1990 development of cold electronics for data collection and digital functions for all sorts of instruments operating directly at working temperatures down to liquid helium.
Progress with cold electronics required testing the operation of all manufactured electronic systems when dunked in liquid nitrogen and liquid helium baths. Only 5% were found to keep working and these were selected to enable the development of cold electronics to move forward. The findings were published in 1992 during a conference in Houston, Texas, USA, when the main application was for instruments on the very large model aircraft in the very large cryogenic wind tunnels at Southampton University Aeronautics Department, NASA Langley, Virginia, USA, and Cologne, Germany.
These findings on cold electronics are now providing the grounds work for Quantum Computing at liquid helium temperatures in 2021.
Successful development of cryogenic concrete and frost-proof concrete as building materials was a straightforward finding, with collaboration from other departments at Southampton University.
Conventional concrete contains a surplus of free water after the concrete paste has hardened to a high strength structural solid. Subsequent removal of this surplus water by vacuum pumping, enables the structural solid to avoid crumbling, below the ice point at 273 K: the frost proof concrete is now also much stronger.
Following his many contributions to cryogenic technology, Paul's multiple areas of research have included the study of different foam materials at temperature ranges from 273 K down to Liquid Nitrogen at 77 and LNG at 120K.
Computer controlled production of thermal conductivity and insulation data enabled rapid testing of many possible insulation materials, in particular to reduce the expensive boil-off of LNG gas from stationary storage and shipping tanks.
Paul's unique up-to-date data on foams will also be valuable in the global distribution of Coronavirus 19 vaccines when/if they require freezing down to 193 K in thousands of low loss containers.
Paul's low conductivity insulations data will also be used for the next generation of space rockets using LNG as rocket fuel, in place of liquid hydrogen, enabling much larger rocket loads flying into space, to the Moon and Mars and beyond, as soon as 2030.
In conclusion, this obituary shows just some of the contributions Paul has made to cryogenic technology over 50 years of research engineering, all of which are being used today, and will be carried into world-wide future applications.
He will be greatly missed by all research and teaching staff together with the hundreds of former students of the Institute of Cryogenics, and will be remembered in countless ways by cryogenic engineers around the world.
His contribution to the revolution in cryogenics will never be forgotten.

Review of Air Liquide last 2K Cryoplant projects and last turbomachine developments
Authors: J.-M. Bernhardt, C. Gondrand, Y. Fabre, P. Dauguet
Abstract:
Refrigeration power at 1.8K or 2K is needed for most of the large particle accelerators, in order
to get optimised operating conditions of superconducting RF cavities. Air Liquide has
developed (since the 80's) Cryogenic Centrifugal Compressors in order to decrease the
pressure on helium baths down to liquid/gas equilibrium pressure in the range 10-30 mbar abs.
for 1.8K-2K helium bath temperatures. These compressors have demonstrated their reliability
and efficiency, with references successfully operated for more than 10 to 30 years at CEA Tore
Supra (now WEST), JLAB CEBAF and CERN LHC. The projects needing 1.8K - 2 K
refrigeration have multiplied in the last 10 years thanks to huge investments of US, Chinese
and Korean governments in the field of accelerators, giving us opportunities to design,
manufacture, install and start-up new 2K Cryoplants and apply our last turbomachine
developments to these projects. The presentation will be a short review of some of the last Air
Liquide 2K Cryoplant projects and turbomachine developments.

Announcements | March 29th, 2020

The 28thICEC-ICMC2020 has been canceled and postponed to 2022. Hereafter you may read the official communication of the Organizing Commettee.

Dear colleagues,

we hope this message finds you well.
In recent weeks, the outbreak of the novel coronavirus (COVID-19) worldwide has raised great health concerns and heavily impacted our societies. We would like to take this opportunity to wish you and your family all safe and healthy. The organizing committees of the ICEC28-ICMC 2020 has been closely monitoring the developments of the COVID-19 in the past months. We have thoroughly investigated and discussed various factors impacting the conference with the ICEC & ICMC committee members, health officials, academics and industries. After careful consideration and comprehensive evaluation of currently available information, including the escalating health concerns, possible restrictions on international traveling, ongoing
uncertainties of the virus development, etc., we have made the difficult decision to cancel the ICEC28-ICMC 2020, originally scheduled on 31st August – 4th September
in Hangzhou, China (www.icec28-icmc2020.org).

We understand this might be disappointing for those who love the ICEC-ICMC for years and our young-generation colleagues as well. However, we must put your health, safety and security on our highest priorities. All the financial supports received from the international and domestic sponsors will be 100% returned as soon as possible. Fortunately, we would like to further update you that, as kindly approved by the ICEC-ICMC committees, the next conference ICEC28-ICMC 2022 will be still held in Hangzhou, China in 2022 in order to maintain the long-lasting tradition of alternating between Asia and Europe. The ICEC-ICMC conference to be organized by CERN, originally planned in 2022, is shifted to 2024. We sincerely hope that you will continue to support our cryogenic society by attending the ICEC28-ICMC 2022.

We will be very grateful if you could kindly share the above news to your colleagues. We extend our profound thanks to our colleagues around the world for your understanding, suggestions and support. We will do our best to welcome you and serve you a successful ICEC28-ICMC 2022 in Hangzhou, China. Facing to the unprecedented challenge together, we believe the normal world will and must come back soon.

Please stay safe and stay healthy.

Sincerely yours,
ICEC28-ICMC 2020

ECD2020 postponed

Announcements | March 20th, 2020

In view of the worldwide developments of the Corona-crisis we decided to postpone the European Cryogenics Days. At this moment,  the situation in Europa is rapidly deteriorating and it is unclear what the coming weeks will bring. Anticipating on earlier developments in China, we hope that by the end of May the worst is over, but most probably the situation of daily life will not yet have returned to “normal”. It is not decided yet whether the ECD will be postponed to later this year, or whether it is completely canceled and the next ECD will be the one in 2021.

On behalf of the local organizing committee and the Board of the CSE,
Marcel ter Brake and Srinivas Vanapalli

In case that not the full period of three weeks can be made available by a prospective participant, individual solutions can be arranged.

Detailed information about the application process and the program of the course may be found on the flyer or at the dedicated webpage.

You may use moreover the enclosed flyer to inform potentially interested persons.
Since 2008 the ECC collects  participants from all over Europe.

For interested young professionals often a sponsorship arrangement could be agreed with the respective employer to allow an additional participation.  

Applications should be sent until end of April. Later applications can be regarded only in case of remaining places or by waiting list. The course usually is overbooked, therefore early applications are suggested. For the same reason, fitting pre-requisitions and a specific cryogenic interest should be demonstrated.
